HDPE Fitting
SDR6 & SDR9 HDPE Fitting
HDPE high-pressure pipe fittings are made from high-strength grades of HDPE, typically PE100 or PE100-RC, designed for use in systems with higher working pressures — often ranging from PN16 up to PN25 (and in some specialized cases, even higher).

- Minimum order quantity: trial order or mixed loading of 1*20 feet container.
Detailed description of SDR6 & SDR9 HDPE Fitting:
HDPE high pressure grade pipe fittings include equal diameter straight, reducing straight, flange, tee, elbow, joint, etc., mainly hot melt butt joint, electric fusion connection and flange connection, etc.
HDPE high-pressure grade pipe fittings are often made of thick-walled pipe blanks and rods. They can be made into various shapes of pipe fittings, such as elbows, tees, crosses, reducers, pipe caps, etc., through CNC machining and other methods. They can solve the problem of difficult processing in injection molding and meet the design and installation requirements of complex pipeline systems.
In order to withstand high pressure, HDPE high-pressure grade pipe fittings are usually designed with thick-walled structures. During manufacturing, special extrusion or injection molding equipment is used to process HDPE raw materials into thick-walled pipe blanks or pipe fittings. Then, through precision processes such as CNC machining, the blanks are further processed and formed to ensure the dimensional accuracy and wall thickness uniformity of the pipe fittings to meet the strength requirements of different pressure levels.
Features and advantages of SDR6 & SDR9 HDPE Fitting:
High pressure resistance: This is the main feature of SDR6 & SDR9 HDPE Fitting, which can withstand pressures of PN10 (1.0MPa)
and above, up to PN32 or even higher. Its pressure resistance depends not only on the strength of the material
itself, but also on the reasonable structural design and high-quality manufacturing process, which enables it to
operate safely and stably under high pressure environments.
Good sealing: Whether it is hot-melt butt, electric fusion connection or flange connection, SDR6 & SDR9 HDPE Fitting
can achieve good sealing effects. In particular, hot-melt and electric fusion connections can form an integrated
sealing joint to effectively prevent medium leakage, which is crucial for pipeline systems that transport flammable,
explosive or toxic and harmful media at high pressure.
Corrosion resistance and wear resistance: HDPE material itself has excellent corrosion resistance, has erosion resistance to most chemical substances, and can
resist corrosion from substances such as acids, alkalis and salts in the transport medium. At the same time, in the
transportation of some media containing solid particles, such as mine tailings discharge, HDPE high pressure grade
pipe fittings also show good wear resistance, which can extend the service life of the fittings.
Flexibility and impact resistance: SDR6 & SDR9 HDPE Fitting have a certain flexibility and can adapt to a certain degree of pipeline
deformation and ground settlement. At the same time, it also has good impact resistance. When subjected to external
force impact, it is not easy to break or damage, which improves the safety and reliability of the pipeline
system.

HDPE high-pressure grade pipe fittings are mainly used in the following scenarios:
Municipal engineering: widely used in the construction of urban water supply, drainage, gas, heat and other pipeline systems.
Industrial field: used to transport various corrosive or non-corrosive fluid media in chemical, petroleum, pharmaceutical and
other industrial enterprises.
Agricultural irrigation: in agricultural irrigation systems, it is often used to
connect irrigation pipes to transport water to irrigation areas such as farmland and orchards. Its wear-resistant
and corrosion-resistant characteristics can adapt to various water quality and soil conditions in the farmland
environment, and provide sufficient moisture for crops in a long-term and stable manner.
Power communication: also used in the laying of power cable protection pipes and communication pipes. HDPE high-pressure grade pipe
fittings can connect the protection pipes into a continuous pipeline system, provide reliable protection for cables
and communication lines, prevent damage to the lines by external factors, and facilitate construction and
maintenance.
