In piping, a nipple is a connection made up of a short tube, usually at each end of a male tube, to connect the other two connections.
History of PE production
Polyethylene was first coincidentally synthesized by German chemist Hans Von Pechmann. He died in 1898
Heating diazomethane synthesized a white wax compound, later called polyethylene. The first industrial synthesis of polyethylene was accidentally discovered by the famous chemists in 1933 by Ezek Nast and Reynoldergison. The two scientists obtained wax-like substances by heating the mixture of ethylene and benzaldehyde at high pressure.
The reaction was due to the presence of oxygenated impurities in the apparatus used as the polymerization initiator. In 1935 Michael Prin, another scientist, developed this method and synthesized polyethylene under high pressure, which became the basis for industrial production of LDPE in 1939.
One of the most important advantages of polyethylene pipes compared to other types of pipes is its easy connectivity. Pipe Fittings are used in such cases as changing the angle of the pipeline route, changing the diameter, connecting the pipe parts and so on. In various applications, polyethylene pipes include screw fittings, belts, gear fittings, high pressure polyethylene fittings for butt welding, polyethylene sewage welding fittings, electro fusion and handheld fittings.
Polyethylene pipelines are connected to different projects and applications by various PEs (electro fusion, welding and twisting) depending on their needs in different projects. For example, gas projects use electro fusion connections, and water supply projects use screw connections to atmospheric pressure. The rest of the project uses polyethylene welding fittings according to German DIN16963 standard.
types of pipe fittings or plumber fittings :
1. Polyethylene screw or polyethylene thread or polyethylene mechanical thread for polyethylene pipes, usually consist of five parts as follows: housing, casing, spacer, bushing, and ering.
Since the outer diameter of polyethylene pipes with a certain tolerance must be suitable for the diameter of the inner threads, and since in the hard polyethylene pipes, the wall thickness of the pipes of different factories is not necessarily the same, so if it is intended for connection Pipes Use Screw Connection This type of connection must be manufactured by the pipe manufacturer to allow for connection.
Polyethylene screw joints are used in plumbing systems to directly connect pipes or parts of pipes to suit different sizes (conversion), knee, tee, etc. or for other things such as adjusting or measuring fluid flow.
2. Polyethylene belt or polyethylene split belt or polyethylene connector consist of two pieces of metal or polyethylene semicircle that are mounted on a tube by two or more bolts mounted on the holes on either side. They are tied together.
3. Polyethylene gear joints are used in metallic piping and steel including steel and galvanized.

Application of PE pipe:
Polyethylene is widely used in the production of all kinds of plastic used in the kitchen and food industries. LDPE is used in the manufacture of lightweight plastic containers as well as plastic bags. HDPE is used in the production of milk containers and liquids and in all types of kitchen plastic. MDPEs are commonly used in the manufacture of pipes and fittings.
LLDPE is widely used in the manufacture of flexible plastic materials such as bending tubes because of its high flexibility. Recently, there has been a great deal of research in the production of long chain polyethylene with short branches. These PEs are essentially HDPE with a number of side branches. These polyethylenes have a combination of HDPE strength and LDPE flexibility.
what is nipple fitting used for?
Nipples are used to prevent plumbing from connecting to a water heater or other plumbing. They are used to insert hoses or end tubes.
Application of screw (mechanical) joints
Screw fittings are used for all soft polyethylene pipes with an outer diameter of 1 to 2 mm.This type of connection is widely used in agricultural and water distribution networks.
Application of polyethylene belt
Used for splitting polyethylene and polypropylene pipelines.
Application of polyethylene gear joints:
These joints, which are easily used as a variety of metal and galvanized joints, do not have any adverse effects on drinking water and, due to surface smoothness, minimize the effect of pressure drop and algae growth on water.Very comfortable to use – Cheap and lightweight products are the hallmarks of this type of fitting
gas nipple fittings used in the pipeline route for the transmission of gas (gas or piping). The fittings are mainly of steel and have standard types of joints and joints. Among the types of fittings, the gas knee is the most widely used. In order to connect them to pipes, electric welding is used and they have different thicknesses and materials.
Where is cheapest pipe and fittings found?
Polyethylene promenades are made of pe80, pe63, pe40 and pe100 materials. The final price of these pipes varies depending on the purity of the raw material for pipe production. Material purity means the amount of raw material mixed with the waste material. The scrap materials are made from grinding consumed polyethylene pipes. Polyethylene pipes made of scrap materials such as granules or compds have their own applications. For example, “sheaths are used for power cables or fiber optic.” But for high pressure sensitive applications or for projects where welding of PE is required, high quality pipes should be used. Most PE producers use their own waste line in their production pipes.
Polyethylene materials used in the production of polyethylene pipes, the price of these materials in the stock market is constantly fluctuating and there is no relative stability in the price of polyethylene pipes. Many other factors, such as exchange rates, freight costs, electricity costs and personnel costs, and many more, may have an impact on the final price of PE and the price list. So manufacturers and sellers give their prices to customers on a daily basis, with a one-day validity period, and bidding is a very high risk.
Also, the price of PE depends on the diameter and pressure of the pipe. Polyethylene pipes start from 20mm in diameter and eventually lead to 2400mm in massive designs. Polyethylene pipes are marketed under various pressures and buyers make purchases according to their needs. These advantages have led to the replacement of water-resistant polyethylene pipes with metal and concrete pipes. The main use of PE pipes is for water transfer outside the city or within the city for major divisions.
What are the properties of nipple fitting?
Polyethylene pipes can be the best choice for fluid transmission systems in various industrial projects, power plants, sewage transmission lines, drip irrigation and sprinkler systems, gas transmission lines, water transmission lines and water supply networks.
Easy connectivity, high strength, non-leakage and high flexibility, high resistance to temperature changes, excellent earthquake and drift resistance, corrosion resistance, rot and wear, impact resistance, high resistance UV, rodent resistance, termites and microorganisms, low weight, low maintenance costs, cost savings due to bond strength due to weld strength of polyethylene pipe, saving on fluid transfer costs due to No leakage in PE connections, product matching with tail The different benefits, production of pipes based on expected working pressure, and production of pipes based on the required service life are some of the benefits of polyethylene pipes, which are the same products of the company.
The pipe socket method is similar to the screw connections for small pipes. But leakage prevention is guaranteed. This is an important factor in the transportation of materials.
Buy bulk fittings and pipes with low price
The price of PE depends on the diameter and pressure of the pipe. Polyethylene pipes start from 20mm in diameter and eventually lead to 2400mm in massive designs. Polyethylene pipes are marketed under various pressures and buyers make purchases according to their needs. These advantages have led to the replacement of water-resistant polyethylene pipes with metal and concrete pipes. The main use of PE pipes is for water transfer outside the city or within the city for major divisions.
The price of the PE pipe and its weight is directly related to the pipe working pressure, the higher the pressure, the higher the pipe weight and price. Polyethylene pipes are marketed from 2.5 times to 20 times. Consideration should be given to purchasing polyethylene pipes and polyethylene fittings for consumables, factory equipment, factory credibility and reputation.
Find The Best Nipple Fitting Suppliers and Manufacturers
The injection molding plant puts the injection devices side by side and feeds the raw material pipes to the devices through silos. High pressure injection injectors (up to 250 bar), PE wrenches and electro fusion joints are all manufactured by injection machines.
The polyethylene fittings factory must have a quality control laboratory. The quality control laboratory must have 17025 certification and other required standards and use appropriate equipment and up-to-date laboratory engineers and technicians.
The fitting plant is not just about producing and testing the product, and one of the most important parts is packing and transporting PE to the customer site and project site. The joints shall be packaged in such a way that they do not interfere with each other and shall be handled with care so that the outer body and edges of the joints are not damaged and the carton should be packed where possible. Small injectable joints and screw joints are packaged in cartons due to their small size, which is convenient and safe, but conventional and large pressure and high pressure joints cannot be considered conventional packing. They wrap around large polyethylene joints and connecting heads with bubble liner and glue on regular plastic and wooden pallets and straps as fast as possible to hold them firmly in place.
Important: Purchase your fittings from a manufacturer and manufacturer to produce polyethylene pipes and fittings and not be the only manufacturer.

The factory for producing polyethylene fittings can vary depending on the type of fittings it produces. But no matter what type of connections are produced, the plant must be clean, tidy and fully optimized, with safety considerations in place to ensure the safety of device operators. The polyethylene fittings plant should have a storage area where the raw material is stored safely and regularly.
The fitting plant is better qualified to have obtained the ISO18001 Occupational Health and Environmental Certificate ISO 14001 from a recent ISO certification from a reputable institution, and the HSE must comply with the factory environment.
Production lines for PEs If there is a type of PE material to be imported as raw materials, there should be silos for storing raw materials to feed the equipment alongside the production lines and machines.
Fittings have a high percentage of polyethylene waste production, especially injectors, as well as machined fittings such as polyethylene flanges, which are shaved from a molded sheet. Waste should not be endorsed by the finished product and 100% confidence in the finished product.
The difference between pipe nipple and pipe coupling
The nipple of the pipe is of straight pipe length with male thread at both ends.
It is the connector or a coupling that exists at both ends. Nipples are used to prevent plumbing from connecting to a water heater or other plumbing.
