Electrofusion joints are used for gas projects and screw joints for hydro projects up to 10 bar pressure. The rest of the project uses polyethylene welding fittings according to the German standard DIN16963. It should be noted that the domestic sewage system does not comply with the above rules. read more about the pipe fittings, poly pipe fittings, pvc pipe fittings, types of pipe fittings, polyethylene pipe fittings catalogue, and brass compression fittings for poly pipe.


What are the different types of plumbing fittings?

Plumbing fittings are components that help us:

  • Change the direction of the pipe such as: knee and tee
  • Change the size of the tube such as the conversion and tee conversion
  • Attach various equipment to the pipe such as: Masseur nut
  • Close the pipe path such as: cap and cork

Plumbing fittings category:

  • Knee
  • Tee
  • Convert
  • Masore nut
  • Intersection
  • Cap
  • Bush
  • Walkable connection
  • Ult (Voldwalt, Sackolt, Treadwalt)
  • Knee long radius
  • Flange

Classification of fittings by pipe connection:

  • Weld or butt weld joints
  • Socket weld
  • Threaded gear
  • Flanged flange
  • Spigot spigot
  • Buttress Polypropylene Screw

Here are some of the connections:


In a knee joint plumbing system, more joints are used. The use of the knee makes it easy to change the direction of the tube. The knees are available in two types: 90 degrees and 45 degrees, although they can be cut at any angle. The knees are produced in two types of short radius and long radius.

90 degree knee

The 90 degree angle changes the direction of the pipe 90 degrees and there are two types of long radius and short radius.

Knee 45 degrees

The knee is rotated 45 degrees between the two tubes and changes its direction 45 degrees.

Knee long radius

At a long radius knee, the radius of the knee is 1.5 times the nominal diameter of the tube. A high radius knee is usually used in systems that have a lower pressure drop. Also, the knee of the long radius takes up more space than the knee of the short radius.

Knee short radius

The knee has a radial short radius equal to the nominal size of the tube. A short radius knee is used where less space is needed. This type of knee has a higher pressure drop due to a sudden change in the direction of the tube.

Knee Conversion

The replacement knee is used to change the direction and size of the tube at the same time. The conversion knee makes fewer connections to the plumbing system. In addition, changing the pipe direction while reducing its size reduces the turbulence and turbulence effects of the current and reduces the corrosion caused by the turbulence. These features prevent a sharp drop in pressure on the line.


Long-range knees are known as bends or bends, and are less compressive due to their gradual change in pipe and the larger radius. These knees have a radius of either 3D or 5D and are available where D is the diameter of the tube.


The knee is not a standard type of joint and is made of tubes. Usually these types of knees are made in large sizes because the cost of knees in large sizes is very high. The use of hand-knees is done in low pressure water conveyors. These types of knees can be manufactured from welding 2, 3, and 5 pipe sections, which we can see in the form of the types.

How do you connect plastic pipes to plumbing?

Polyethylene pipes or joints are connected by heat welding or mechanical joints. Polyethylene pipes can be connected to other pipes using pressure connections, flanges, etc. The user has many types of connections to choose from. Each of these connections has its own advantages and disadvantages in the particular connection conditions that the user faces. When connecting polyethylene pipes to each other with fittings, it is important to first determine the standard fittings and fittings, then use standard fittings to connect, and finally the method of connection by the contractors to be correct. The equipment used to perform the welding joint process must be specially designed to work with the desired pipe and welding instructions. In addition, equipment must be well maintained and capable of operating in accordance with the stated technical specifications

Can you use compression fittings on PEX pipe?

PEX (5-layer tube) is a heat-resistant polymer made of heavy duty polyethylene after cross-linking and structural modification. Networking is applicable in many ways. In all different technology-based approaches, the goal is to create and communicate between individual branches in a mass through radical reactions. The number and density of these bands determine the percentage of cross-linking. This percentage distinguishes the types of pixels from each other or even the pixels that are presented under one name. There are many ways to network. The three main methods are:

  • Peroxide method
  • Flow method
  • Radiation method

In world standards, the following three methods are obtained:

  • PEX-A
  • PEX-B
  • PEX-C

It should be noted that the PEX tube (5-layer tube) is a type of PEX-a which is used in the preparation of peroxide but in another way. It is a very new way to perform static, dynamic mixing and mixing of solids and liquids, pipe forming and even heat using highly sophisticated, reliable equipment consistently, consistently and consistently.

What is a tee in plumbing?

Tee is one of the most widely used types of PE connectors, which are divided into two categories:

  • triple
  • Convert Three

It should be noted that their convertible teas are divided into two groups of convertible teasers with convertible and navel teasers. Polyethylene tripods are produced in two ways:

  • Injection method: Integrated with plastic injection method
  • Coupling Method: Multipurpose using pipe welding

Triad is widely used in various industries, especially transmission lines and networks.

Advantages of using PE pipes

  • Type 1: Density, low heat resistance and good flexibility are the benefits of this type.
  • Type II: Medium and slightly harder than type I and resistant to high temperatures and have better expansion potential.
  • Type III: It is much heavier in weight and has a higher density and has the highest physical properties in terms of resistance – expansion capacity – degree of hardness – roughness coefficient and is therefore widely used in water supply.

Tip 1: Coupling PE pipes in different gear – flange – brace – orientation and male and piston joints are performed by thermal and welding.

Tip 2: Gear connection is applicable to all heavy plastic tubes and four inches down.

Best brands of pipe fittings in the world

Today, with the large number of buildings in the country, the use of plumbing has naturally increased. Traditional plumbing certainly does not meet the needs of this era. For this reason, modern buildings use plumbing and modern pipes such as galvanized pipes and cast iron pipes. The type of pipe used can determine which pipe is the best model for your work. Try to choose the the best pipes brands you use. The best pipes brands of the highest quality made by the finest and finest raw materials made by the latest machinery in the world and in accordance with the latest domestic and foreign standards.

Now we want to explain to you construction pipes and installation pipes. Different types of pipes are commonly used in building installations, which can be divided into different types depending on their sex, application and how they are divided. Each of the building pipes should be used locally because building plumbing is an important part of construction so it is of the utmost importance. Building plumbing has several components, including:

  • Hot and cold water piping
  • Boiler and package plumbing
  • Plumbing Drainage
  • gas piping

The list above is part of a variety of construction pipes. Note that the above are plumbing sections of the building and each of these tubes has different types and each pipe is suitable for the same plumbing part of the building. Each pipe used in one part of the facility has its own advantages and disadvantages.

Which countries have cheap products for piping systems?

PVC pipe and fittings industry, which has been in Iran for over 50 years, is proud to produce and supply Iran’s first polymer tubes. Although the first PVC pipes made in Iran were for the water supply sector, special conditions after the civil war and the absence of a coherent labor union led to the emergence of other younger polymer pipes in the water supply sector. In this battle, PVC pipes not only lost much of their market but also lost many of their inherent identities.

Cheap raw materials for producing plumbing tee

It should be said that the process of producing polyethylene pipes is carried out by an extrusion method in which the raw materials are inserted into the extruder by the granule and fused with heat. The melted material is pushed forward by the screw (spiral rod) and then molded into the extruder. The cooked material goes through the calibration after removing the mold and forms in a vacuum tank with appropriate pressure. After calibration, the surface of the tube is cooled by layers of cold water.

Melting of high temperature polyethylene gradually decreases after placing the mold in a vacuum tank and then in cooling tanks using cold water. The polyethylene pipe produced by the landing gear is gradually drawn from the vacuum and cooling tanks and recorded by the marking machine, technical specifications, production date, standard mark and corporate mark and then by the metric cutting machine. Different and definitive cut. All production processes are controlled and controlled by fully automatic machines to ensure that the quality of the finished product is acceptable to the company name and standards.

The process of producing high polyethylene pipes was very short and the machinery and equipment of the production line during the production of polyethylene pipes were not discussed. Single wall polyethylene is produced in this way and differs only in dimensions and model of the device and is produced in extrusion throughout the PE pipe. 110mm polyethylene pipes are produced as coils and this does not change the overall production process, only at the end of the coil production line that carries the PE coil.

Lead-Free Brass Compression Fittings On Sale

Brass valves are one of the valves used in construction facilities. Brass is a copper alloy that makes brass equipment much more durable and durable than plastic. Unlike plastic valves and P.V.C, brass valves are corrosion resistant and have a longer shelf life. Brass valves can also withstand higher temperatures and these features are the brass valve intended for the piping system.

Why Use Brass Valves?

Due to the important role of valves in domestic water piping, the type of alloy used in these valves is of double importance. According to national facility standards, all components in the valve assembly must be such that they have no effect on the taste, color or odor of the water. Brass valves come in two categories, lead and lead. The lead type of these dangerous and pathogenic valves is commonly found in counterfeit goods on the market.

Benefits of Brass Valves

The benefits of brass valves are:

  • Reasonable price compared to metal valves
  • Easy welding
  • High durability against moisture and water vapor
