Polyethylene Pipe Black Pe Pipe Thermal Fusion Connection

Where to buy a ring tensile testing machine for pe pipe

The material of the investigated pipe is high-density polyethylene (HDPE), which is commonly The ring hoop tensile tests are conducted on specimens cut out from the pipe with thickness in order to test the RHTT specimen in the transverse direction. tensile testing machine is used to carry out all tensile tests of RHTT.

Feature

■ Good sanitary performance: no heavy metal salt stabilizer is added during the processing of PE pipe, the material is no scale layer, no breeding bacteria, and it can solve the secondary pollution of urban drinking water.

■ Excellent corrosion resistance: Except for a few strong oxidants, it can withstand the corrosion of various chemical media; no electrochemical corrosion.

■ Long service life: Under rated temperature and pressure conditions, PE pipes can be used safely for more than 50 years.

■ Good impact resistance: PE pipe has good toughness, high impact strength, and heavy objects directly pressing through the pipeline will not cause the pipeline to break.

■ Reliable connection performance: The strength of the PE pipe's hot-melt or electric fusion interface is higher than that of the pipe body, and the joints will not be broken due to soil movement or live load.

■ Good construction performance: light weight pipeline, simple welding process, convenient construction, and low comprehensive engineering cost.

Connection of pipes:

■ Electric thermal fusion: Adopt special electric thermal welding machine to connect straight pipe and straight pipe, straight pipe and pipe fittings. Generally used for tubes below 160mm.

■ Hot-melt butt connection: It is connected by a special butt welder pipe, which is generally used for pipes above 160mm.

■ Steel-plastic connection: It can be connected by flanges, threaded fasteners, etc.

■ In order to facilitate construction and ensure construction quality, corresponding tools should also be prepared.

How to calculate pe pipe size

The PE pipe size bai depends on the outer diameter. The symbols are DN, dn, de, Φ before DN means the nominal straight diameter, for example, the inner diameter is indicated on the pipe zhi, and the PE pipe is initially set to dao, and DN also means the inner diameter. The model of PE pipe with an outer diameter of 110 was later due to the introduction of new standards in China, and now DE and DN have been uniformly expressed as the outer diameter of the PE pipe, so now DN and DE both refer to the meaning of the outer diameter of the PE pipe. PE pipes are divided into PE80 and PEPE100 according to raw materials, PN represents the nominal pressure of the water pipe, and SDR represents the ratio of outer diameter to wall thickness. For example, Φ110*18.5 (110 means outer diameter, 18.5 means wall thickness) or DN100PN10 (100 means outer diameter, PN10 means ten-meter pressure) DN100=Φ110.

How do you connect pe or pex pipe to copper pipe?

The fastest and easiest way to connect PEX directly to copper pipe is by using SharkBite connections. These connections require no tools and no soldering. If you aren't using SharkBite connections you will need a copper pipe adapter also known as a female sweat adapter.

1. The PE pipe of the tap water pipe system in cities and towns is sanitary,  and non-fouling. It is more suitable for urban and rural water supply main pipes and buried pipes. It is safe, hygienic, economical, convenient in construction and long in service life.

2. Urban gas transmission pipelines Because PE pipes have good creep resistance and economy, they have gradually replaced ductile iron pipes for urban gas transmission.

3. The replaceable cement pipe, cast iron pipe and steel pipe are used for the old network reconstruction project. It does not require large-area excavation, and is convenient for construction and low in cost. It can be widely used in the old city pipe network reconstruction.

4. Industrial raw material conveying pipes Chemical, chemical fiber, food, forestry, pharmaceutical, light industry, papermaking, metallurgy and other industrial raw material conveying pipes.

5. Garden greening water supply pipe network Garden greening requires a large number of water pipelines. The flexibility and low cost of PE pipes make it the best choice.

6. Sewage discharge pipe PE pipe has unique corrosion resistance and can be used for industrial wastewater and sewage discharge with low cost and maintenance costs.

7. Mineral sand and mud conveying PE pipelines are highly resistant to stress, abrasion and corrosion, and can be widely used for conveying ores, coal ash and river dredging mud.

8. The PE pipe of agricultural irrigation pipe has smooth inner wall, large flow, can be constructed across roads, has good impact resistance, and is an ideal pipe for agricultural irrigation.

9. Marine pipe PE pipe is light in weight and easy to connect, and can be widely used in water supply and drainage of large ships.

10. The PE pipe for seawater desalination has a long service life and high cost performance, and is widely used in seawater desalination projects.

11. Rural biogas pipelines are being used in large-scale rural biogas projects due to their good economics.

12. Other applications PE pipes can also be widely used in other fields, such as power, communication jackets, farmland irrigation, landfills, geothermal air conditioning, deep-sea aquaculture, buried fire-fighting pipes, and so on.
