200 psi (pounds per square inch, about 1.38 MPa) polyethylene pipe is a high-pressure plastic pipe, mainly used for conveying liquid or gas media, suitable for municipal water supply, gas transmission, industrial fluid transmission and other fields. Polyethylene pipes of this pressure grade are usually made of high-density polyethylene (HDPE) or medium-density polyethylene (MDPE) materials, with excellent pressure resistance, corrosion resistance and long life.
200 psi polyethylene pipe complies with international standards (such as ISO 4427, ASTM D3035, etc.), can withstand high internal pressure while maintaining flexibility and impact resistance, and is particularly suitable for pipeline projects under buried laying and complex terrain conditions.
1. Excellent pressure resistance
The rated pressure of 200 psi (1.38 MPa) makes it suitable for medium and high pressure fluid delivery systems.
Use high-strength polyethylene materials such as PE100 or PE4710 to ensure long-term pressure stability.
2. Excellent chemical corrosion resistance
It has strong resistance to chemicals such as acids, alkalis, and salts, and is suitable for industries such as chemical and sewage treatment.
It will not be damaged by electrochemical corrosion, and its service life can reach more than 50 years.
3. Good flexibility and impact resistance
Compared with metal pipes, polyethylene pipes have higher flexibility and can adapt to environmental changes such as foundation settlement and earthquakes.
It still maintains good toughness in low temperature environments and is not easy to crack.
4. Low fluid resistance and efficient delivery
The inner wall is smooth and the friction coefficient is low, which reduces pressure loss and improves delivery efficiency.
It is not easy to scale after long-term use and has low maintenance costs.
5. Environmental protection and safety
Non-toxic, non-polluting, and in compliance with drinking water standards (such as NSF/ANSI 61 certification).
The joints are butt fusion or electrofusion to ensure zero leakage and avoid medium contamination.
1. Municipal water supply system
Applicable to urban main water supply network and secondary water supply system to ensure stable and safe drinking water delivery.
2. Gas transmission pipeline
Complies with gas pipeline standards (such as EN 1555), used for medium and low pressure natural gas pipelines, with excellent anti-leakage performance.
3. Industrial fluid transportation
Used for conveying corrosive liquids or gaseous media in chemical, petroleum, mining and other industries.
4. Agricultural irrigation system
Applicable to high-pressure drip irrigation and sprinkler irrigation systems to improve water resource utilization.
5. Mine and tailings transportation
Wear-resistant and corrosion-resistant, suitable for high-pressure transportation environments such as slurry and mud.
To ensure the tightness and strength of the pipeline system, 200 psi polyethylene pipe usually adopts the following connection methods:
Butt fusion
Use a Butt fusion machine to heat the pipe end, melt it and press it together to form a high-strength permanent connection.
Applicable to large-diameter pipes (DN≥90mm).
Electrofusion
Adopt Electrofusion Fitting (electrofusion fittings), built-in electric heating wire, and fuse the pipe and fittings after power is turned on.
Applicable to small-diameter pipes or complex construction environments.
Mechanical connection (flange or clamp)
Used in occasions where detachable connections are required, such as valves, pump stations and other equipment interfaces.
200 psi polyethylene pipe has become an important part of modern pressure pipeline systems due to its advantages of high strength, corrosion resistance, long life and environmental safety. With the advancement of technology, it will play a greater role in municipal, industrial, agricultural and other fields, providing more efficient and reliable pipeline solutions for global infrastructure construction.
