Important Standards About PE Pipe Fittings

Polyethylene pipe fittings include all kinds of flanges, injections, thermal fusion, electro fusion, mechanical and so on. These joints are manufactured in various ways, such as injection molding or using thick polyethylene sheet by cutting and turning. Each of these methods has advantages and disadvantages for producing PEs, such as injection molding because of the large size and variety of materials, different materials and pressures, not all of these sizes are available, but in the machining method based on what is on the fitting map, They are machined and will fit perfectly with the map.if you have question about british standard pe pipe fittings you can check out online sites to find an answer to your question.

PE Pipe and Fittings Manufacturers in Asia there are plenty of pe pipe fitting manufacturers in asia which are suppling great pe pipe and fittings.there are great information about those manufacturers an also about iso 4427 certification on the internet.

Types of PE Pipe Fittings

There are different types and styles of connections available that the user can choose from. Each has its own advantages and limitations for any situation that the user may encounter. Contacting various manufacturers for guidance on appropriate applications and styles to join is recommended as described in this document.

Connection by fusion method

The most expensive method of connecting to a tube is H.D.PE. To make a fusion weld, the tube needs to be moved. When connecting to manholes, fusion welding is often difficult. Standard welding methods do not change, but special considerations should be made for wrench, pipe, fusion machine, and general conditions, which are handled by specific codes.

Welding of PE

The most suitable bonding method is polyethylene welding bonding method, if the welding quality is very high, it will have a very high uniformity and interconnection. In this way, connection generation is done at any angle that is effective to facilitate the execution of projects.

Flanged connection

PE flange adapters are used when connecting to metal or some other piping material, or if part of the pipe requires separation. The adapter flange and its shorter version, the “Stub End”, are designed to be one end as large as the PE pipe to connect to. The other end is made with a flange end that provides a structure that eliminates the need for tightening. In most industrial applications, flanges are used to connect holes to solid wall pipes. The flange provides strong, non-leaky connections and can handle the most frequently occurring contractions and expansions. Flanges are also a great way to connect variable materials in the piping process.

Electrofusion Couplings

 Offer a fast, corrosion-resistant joint when using high-efficiency polyethylene holes. Using a single wall pipe does not require pipe or manhole movement. This coupling method of thermal fusion coupling is somewhat different from conventional fusion coupling. The main difference between a conventional thermal fusion and an electroplating is the way in which heat is used.

In the conventional thermal fusion connection, a heating device is used to heat the pipe and surface joints. The electroporation pair is heated internally, or by a conductor in connection with the conductive polymer. Heat is applied to the conductive material in the joints as an electrical current. PE pipe in electro fusion process requires the use of electrofusion coupling.

Polyethylenes are a family of thermoplastic polymers (thermoplastics) that make up the largest share of plastic consumption in the world.

One of the biggest uses in the production of pipes is because of their high importance in this article, polyethylene pipes are discussed. For more information on the properties and applications of polyethylene types, please refer to the article on polyethylene grades.

Polyethylene pipe has the advantages such as ease of loading, easy transportation due to its relatively low weight, quick and easy installation, impact resistance, abrasion resistance, excellent chemical resistance and response, excellent fluid flow inside the tube Comfortable connectivity, high flexibility and versatile connectors.

That’s why the use of these pipes is increasing day by day. One of the most important factors in replacing steel pipes with polyethylene pipes is their permeability to chemicals. Better against organic and inorganic chemicals than metals that affect their performance

Polyethylene Pipe & Fittings Systems in different prices

different kinds of polyethylene pipe and  fittings system have different prices.for example hdpe water pipe has a great variety and each kind has different price.

Various factors affect the quality of PE pipes, the most important of which are:

– Raw material agent: Resin type – Additive (amount and uniformity of addition) – Reinforcer (such as glass fiber reinforced polyethylene)

– Production process: This part of the production depends a lot on the machinery and skill of the technical personnel

– Environmental factor: Application of polyethylene pipe (water pipe or sewage and even for what kind of industrial water consumption or …)

– UV radiation: specific applications (radioactive waves – magnetic waves) – Microbiological effects

– Stress factor: Temperature (defined in the standard PE life assumption is 20 ° C for 50 years. Where the temperature is not 20 ° PE life will vary depending on the temperature. Ethylene is on the surface of the fluid with the environment is the same but if below ground, the fluid temperature is lower than the environment)

– Temperature fluctuations: (We have temperature fluctuations in sewer pipes but we do not have water pipes which cause this temperature fluctuation to wear out)

– Static load: or dead load (the tube beneath the soil is pressurized to the weight of the soil if the pipe is under fluid pressure, the two pressures will partially counteract the effect otherwise the pipe will be damaged. )

– Bardynamic: or traffic load (if the pipe crosses the path the machine is traveling in, the pressure will be higher, it will be difficult to bear this pressure for sewage pipes that do not have fluid pressure)

– Slit and scratch

– Welds: (Most joints are butt welds. If the temperature is exceeded it will affect the pipe life and the system will have problems at the welding location.

Types of PE pipe

Polyethylene pipes can be classified into several general categories:

• Single wall polyethylene pipe

• Double walled polyethylene pipe

• Irrigation pipes



Single wall polyethylene pipe

Polyethylene single tube, including polymer tubes, which can be used at pressures between 2 and 40 bar, with different diameters.

The unique properties of polyethylene pipes compared to other types of pipes have led to the rapid growth of this product in transmission and distribution networks.

(Single wall pipes are used according to Isiri 14427 -1,2 for water supply and IGS-M-PL-014-1 (3) for gas supply.)

Over the past fifty years, the industry, with its advances in the production of polyethylene pipes and fittings, has introduced itself as a viable alternative to steel pipes, PVC, GRP and cast iron. In most cases, replace these pipes as your own.

This generation of pipes is classified into PE 40,32, 80, 100 in the category of polyethylene pipes. The characteristic number listed in these polyethylene grades is called the MRS material, which is the minimum internal pressure resistance required after 5 years of operation at a fluid temperature of 2 ° C.

Increasing the number indicates a further improvement in the quality of manufactured products. The minimum internal pressure is reported to be about 8 MPa for PE 80 and about 10 MPa for PE100.

Accordingly, in many countries there have been many efforts to replace PE100 with PE80.ulyou can also learn about hdpe threaded fittings on the online shopes.

Important standards about pipes and fittings in the world

but there are important standards about pipes and fittings.and it is important for companies to keep up to those standards.each pipe an fittings likespe electrofusion fittings should have some features.

Their most important features are:

  • Polyethylene shows very high impact resistance even at low temperatures. Proper handling of PE with high shrinkage to break is an important advantage in many applications, for example in areas where there is a high risk of earthquakes.
  • Due to the non-polar nature of PE as a high molecular weight hydrocarbon, PE has a high resistance to chemical attack. PE has good resistance to acids, alkali. PE is resistant to oxidizing acids, ketones, aromatic hydrocarbons and chlorinated hydrocarbons.
  • If polyethylene is exposed to direct sunlight for a long period of time, like many natural and plastic materials, it will be damaged by the UV wave of sunlight and degraded by oxygen in the air under the oxidation process. This is why most polyethylene pipes are resistant to UV light by adding carbon block.
  •  Polyethylene pipes can be used in the temperature range from -50 ° C to +60 ° C. At higher temperatures, the tensile strength and hardness of the material are reduced.

PEs have a linear thermal expansion coefficient of 0.15 to 0.20 mm / m 2 which is 1.5 times higher than PVC as long as this is taken into account when planning installation.

The thermal conductivity is 0.38 W / m K. Because the insulation properties are obtained, the PE pipe system is significantly cheaper than a metal-like copper system.

  •  Polyethylene belongs to flammable plastics. The oxygen index reaches 17%. (Materials with 21% oxygen in the air are considered burns).
  • Due to the low water absorption of polyethylene, its electrical properties are hardly affected by continuous water contact. However, these properties can be drastically reduced due to contamination, effects of oxidation media or ambient air. Its specific volumetric resistance is> 1017 Ωcm; dielectric power is 220 kV / mm.
