elbow pe fitting | Explain Manufacturing process of different pipe fittings

elbow pe fitting : Polyethylene pipelines are connected by different polyethylene connections (electro fusion, welding and twisting) according to their needs in different projects and applications. For example, gas projects use electro fusion connections, and water supply projects use screw connections up to ten atmospheric pressure. The rest of the projects use standard PE welding joints. Knee joints are one of the types of ethylene joints that are widely used in transmission lines and networks. The knees are produced in both injection and mating.

pipe fittings chart : One of the most important uses of polyethylene pipes is their use in water and sewage networks. Large and small water supply systems in different areas currently use a variety of PE pipes and fittings.

Water pipes of any length and size need one of a variety of diameter and size polyethylene pipes. The important thing about the water supply network is how to connect the PEs along the pipeline. It is natural to use special connections to connect two PE pipes or to make changes to the piping. In some cases, the volume of water passing through the pipe may be reduced or increased; in some cases, the pipeline may be split into several branches and part of the water flow directed in other directions. In all these cases, the installation of proper connections is necessary.

  • The most important fittings for water supply PE

The connections used for water supply networks are divided into two categories: primary and secondary. The main connections installed on these lines are:

  • High pressure screw PE connections
  • High pressure welding PE
  • Polyethylene Pipe Fittings
  • Polyethylene wastewater fittings
  • Electrofusion joints

In some cases, polyethylene pipes smaller than the main pipe are used as two-sided polyethylene pipe connectors. There are several important factors to consider when using different types of connections in the water supply network. The working pressure and the alignment of the pipe dimensions with the joints at the crankcase is a very important factor that needs to be carefully examined.

types of pipe fittings :PE is one of the types of PE that is used to divert fluid into the PE pipes. PEs are manufactured in 45 and 90 degrees. There are three types of joints available in all types of PE:

Polyethylene knee welding (45 ° and 90 °) Welding in the form of welding lip or BW which is the simplest type of connection in the category of PE. Polyethylene (45 and 90 °) kneading electrofusion, which are bonded to each other in the form of heating elements or wires of this type, in which the flow of electricity is involved in the fusion of polyethylene materials, and are of prime strength and sealing. They are more commonly used in cases of gas transmission and are limited in use in water transmission, due to the high cost of these fittings compared to types of welding or lubrication.

The knee or polyethylene thread that is sealed and tightened by the threads defined in and out of this type of knee and by the inner ear. Polyethylene knees are manufactured in the aforementioned types, in the two cases referred to as the electro-fusion knee and the working or twisting knee sixteen atmospheres and ten atmospheres respectively, in one form at 45 degrees and 90 degrees depending on the type of use. are being used .

Where to buy elbow pe fittings in bulk?

Polyethylene knees are manufactured in a variety of sizes and sizes to suit the needs of each project and in the atmospheres in question, which are manufactured and delivered in the following sizes and types respectively.

  • Polyethylene knee: These types of polyethylene knees are produced in sizes from 20 mm to 125 mm ie 5 inches and at working pressure up to10 atmospheres.
  • Polyethylene kneading welds are manufactured in types of 45  and 90 degrees and have no specific size range and range from 20 mm to 2000 mm in a variety of atmospheres between 4 -32  atmospheres.
  • Polyethylene Knee Electrofusion: These types of joints range from 20 mm to 250 mm as usual and work pressure of 12 and 16 atmospheres.

Price of knee PE

The price of polyethylene knees in each of these types is different depending on the type of application and the dimensions and the pressure it produces.

pipe bends and elbows :Knee ELBOW :  When they want to change the direction and direction of these sections, they use knees that are available in a variety of types, including knee 90 , knee 45 , knee 90 , knee 45 . As one can see from their names when the angle is 90 or 45 degrees, that is, the shift is 90 and 45 degrees, and in both cases the knee gears are inward. The difference between the normal knee and the oblique knee is in the ribs. That is, one side of the gear is outward.

90 degree elbow pipe : 90 Degree PE knee with Maitree method is a standard made of PE products. These joints are manufactured according to the dimensions specified in the standard and the specifications do not indicate the weight of the PE joints and are the only criterion for controlling the dimensions of the joints.

The weight of the PE connections is not similar to the standards specified in the standards and may vary slightly depending on the manufacturing conditions of each component. The 90 degree knee is manufactured according to this standard. This joint (90 degree polyethylene knee) is custom made by customer request and is part of welding joints.

Miter fittings, or welding fittings, are cut from the same pipe as the precision parts of the parts, and are welded together by angle welding machines and specialized fittings. This type of fittings is the best type of PE fittings and if the welding operation is performed according to standard and precision, the welding point and resistive joint will be more than the pipe itself and will be very reliable.

What is an elbow PE fitting?

What is an elbow PE fitting?ELBOW steel welding knee is one of the most widely used joints in industries and installations. The structure of this type of connector is of no complexity and is merely used to change the direction of the pipe. This product is classified into three main categories according to the type of angle in the structure:

Knee 45 degrees

Knee 90 degrees

Knee 180 degrees

We use either of these knees in the case of angles depending on the angle of the pipeline. If you need to change direction in one direction, you can use a 45 degree knee and if there is a change of direction with a radius change, a 90 degree knee is the best choice.

Different uses of elbow PE fittings

ELBOW steel welding knee is one of the most widely used joints in industries and installations. The structure of this type of connector is of no complexity and is merely used to change the direction of the pipe. This product is classified into three main categories according to the type of angle in the structure:

Knee 45 degrees

Knee 90  degrees

Knee180 degrees

We use either of these knees in the case of angles depending on the angle of the pipeline. If you need to change direction in one direction, you can use a 2 degree knee and if there is a change of direction with a radius change, a 2 degree knee is the best choice.

If we want the path to go parallel to the path to the back, then we use a 180 degree U-shaped knee. In this case the pipe path is changed to 180 degrees and returned to the right of way.

The raw material used in this product is carbon steel and stainless steel. Carbon steel is actually a stainless steel with a 5-10 % chromium added to its structure to prevent corrosion. Stainless steel is actually a type of stainless steel that has a chromium content of about 12 % and has a much higher resistance to corrosion due to its higher chromium level. Other categories in the types of gas welding joints are the knee division into two groups of low and high radius knees. Get the Steel Welding Knee Price from the Iron Center website.

What are the different types of fittings?

different types of human elbows : Production and application of seam welded knee joints: Different types of steel knee joints with different angles can be manufactured in both knee joint and mannequins. In all types of welded knees, two edges of stainless steel sheet are melted by a high current electrode or ampere and the edges are welded together. In the case of the Manisman Welding Knee, a seamless primary alloy is provided to produce this type of knee by inserting a hole through the middle of the stainless steel cylinder. Two types of hot and cold rolling are used to produce all kinds of steel welding knees.

  • Welding kneading process by hot rolling method

In the production of hot-rolled steel welding knees, a machine called the Mandrel is used. This method is more expensive than the cold rolling method and has a lower speed in the manufacturing process, but instead the product quality is higher than the cold rolling method. In this method, the pipes are first cut to the appropriate size and then inserted into the mold. The mandrel machine is used to pass the pipes through the mold. The cane-shaped molds are embedded in the furnace and form the inserted tubes to the proper shape.

  • Cold Rolled Steel Welding Knee Manufacturing Process

In the cold rolling or forging method, punch and matrix are used to produce the welding knee. In this method, cut tubes are inserted into special molds to form by punch and hydraulic press. This method has a lot of problems, such as creating a heterogeneous surface at the knee and reducing the size of the pipe during molding compared to standard size. Another disadvantage of the cold method is the possibility of knee cracking after use, which is due to the poor quality of its production method.

What is a sweep elbow?

elbow exhaust pipe :In hot and cold water piping used to connect the pipes to each other, divert the pipe, split or convert the pipe diameter, they use parts called joints or joints. Joints or joints are made in two types of screw or (gear) and welding that are exclusively used in cold, hot and hot water piping, and with a white gear screw because the use of non-galvanized gear joints is difficult. It causes the pipes to become corroded and thus decay. The most commonly used components in the facility are classified as follows:

  • Convertible knee:

This joint is mounted on two ends from the inside and is used to connect parts of different diameters.

  • Knee Tube:

This joint is used for shifting to 90 degrees by 45 degrees, which includes the vertical knee 90 degree – knee 45 degree – the spiral knee and the 90 degree knee or the oblique – the spiral knee 45 degree and the conversion knee.

  • Vertical knee 90 degrees:

It is a joint that is used to change the direction of 90 degrees in plumbing. This joint has two ribs inside.

  • 45 Degree Knee:

Like a 90 degree vertical knee, it is used to change the direction of the pipe with a 45 degree deviation. In sewer piping, where vertical shifting and 90 degree deviation from the vertical knee increase the likelihood of clogging in the pipe, or the use of two 45 degree knee joints and a single brain number increases the radius of curvature. This joint has two ribs inside.

  • 90 Degree Spiral Knee:

This joint, known as the left knee, is similar to a 90-degree vertical knee, but is geared inward and outward, respectively, and is used for the same diameter parts, one piece at the junction and the other at the inside of the gear.

Note: The knee-to-knee coil application is 45  degrees like the left knee, with the difference being 45 degrees.

Can a vent pipe have an elbow?

The 90 degree knee provided by the company is manufactured to German DIN16963 standard. This joint (90 degree polyethylene knee) is custom made by customer request and is part of welding joints. Miter fittings, or welding fittings, are cut from the same pipe as the precision parts of the parts, and are welded together by angle welding machines and specialized fittings.

This type of fittings is the best type of PE fittings and if the welding operation is performed according to standard and precision, the welding point and resistive joint will be more than the pipe itself and will be very reliable. This type of PE fittings is the best type of PE fittings and is of the highest quality in welding locations and is recommended for industrial and high pressure applications. Knee joints are important in sewage piping systems.

How many types of elbow are there?

 

The 90 ° knee made from the tube itself is known for its curved structure and structural resemblance to the knee called knee joints. Sewer polyethylene knees are especially used for changing piping directions and for sealing and leaking pipes. These types of connections are most commonly used under siphons and are available in coiled-coil, bar-coil, and barbed-plate types.

The 90 degree welding knee is one of the most commonly used joints in transmission lines. Depending on the grade and pressure applied to the pipe and the number of components of the knee, various types of this connection are produced.

The 90 degree knee joint is used in pressure water supply systems, water distribution networks, home installations, sewage systems, as well as rain and drip irrigation systems. This knee is known for its number of components. The greater the number of components, the less severe the angle change, which results in less perturbation in the flow of fluid as it crosses the pipeline.
