the characteristics of HDPE pipe
1. Inflaming retarding and static electricity resistance
The antistatic composition and flame retardant composition is uniform distribution in the HDPE pipe body, so the performance will not been affected by long using time.
2. Light weight, convenient installation
HDPE pipe unit weight is only about 1/8 of the steel pipe, 1/3 glass steel pipe, so can greatly reduce the labor intensity of workers, improve work efficiency.
3.Good toughness
Unique material superiority makes HDPE pipe has good toughness, so HDPE pipe can be bent also HDPE pipe can not block the gas.
4. High pressure resistance
Due to HDPE pipe has high density polyethylene so it can bear high pressure.
5. Anti-aging, good rapid crack resistance performance
HDPE pipe aging performance is good, not easy to be embrittled under low temperature, rapid cracking resistant performance is good, can effectively absorb the impact energy, can effectively avoid the fracture accident.
6. Good wear resistance
HDPE pipe wear resistance is 4 times than steel pipe so HDPE pipe has long using life-span and economic superiority.
7. Easy to connect and reliable connection
Can use the hot melt connection, pipe clamp connection or flange connection, so construction is convenient.
PE gas pipe applied fields
This product is mainly used in natural gas, liquefied petroleum gas, artificially gas
transmission and distribution, also can be used in chemical industry, medicine and
papermaking industry.
1,Corrosion resistance: polyethylene (PE) is a kind of inert materials, except a few
strong oxidizer , it resists to various chemical medium erosion, no electrochemical
corrosion, don't need anti-corrosion layer.
2,Nonleakage: PE gas pipeline mainly uses the hot melt connection or fused
connection, make the pipeline system integration. Its interface tensile strength and
blasting strength are higher than the pipe ontology. Therefore, compared with the
rubber seal class joint or other mechanical joints, it does not exist the risk caused by
leakage distortion joint.
3,High toughness: PE gas pipe is a kind of high toughness pipes, fracture extension
rate of PE pipe, commonly more than 500%. .As to the uneven settlement of the
base, its adaptive ability is very strong, has a good aseismic performance. (In 1995, Kobe earthquake happened in Japan, the
PE gas pipeline and PE water supply line
is the only surviving piping system. Because of this,after the earthquake ,Japan
began to promote to use polyethylene pipe in gas field.)
4,Excellent reelability: the reelability of polyethylene make PE gas pipe can be rolled, used in the construction does not need slot, PE gas pipeline easy to be changed
in accordance with the requirements of construct methods.
5,Good resistance to scratches and resistance to crack: any pipe scratches can't be avoided in construction, scratches triggering caused materials stress concentration,
and PE gas pipe has excellent resistance to quickly crack propagation (RCP) and
slow crack growth (SCG), and more excellent resistance scratches ability.
6,Long service life: in the rated temperature and pressure conditions, PE gas pipeline can safe to use more than 50 years.
7,Light weight, lower maintenance cost: can use the excavation way, convenient,
improve the efficiency of construction project.
