Paipu Gas Polyethylene (Paipu kinoea PE, short for PE gas pipe) is a pipeline system made of high density polyethylene (HDPE) or medium density polyethylene (MDPE) as raw materials through extrusion molding process, specially designed for the transportation of natural gas, kinoea ʻaila liquefied (LPG) and other gas media.
Paipu Gas Polyethylene (Paipu kinoea PE, short for PE gas pipe) is a pipeline system made of high density polyethylene (HDPE) or medium density polyethylene (MDPE) as raw materials through extrusion molding process, specially designed for the transportation of natural gas, kinoea ʻaila liquefied (LPG) and other gas media. Hoʻohālikelike ʻia me nā paipu metala kahiko, PE gas pipe has become the preferred material in the field of global gas transportation due to its characteristics of light weight, pale ʻino, strong impact resistance and long life.
Details of Black Polyethylene Gas Pipe
ʻO ke kūpaʻa ʻino:PE material has natural resistance to chemical corrosion, electrochemical corrosion and soil microbial erosion, without additional anti-corrosion treatment.
Flexibility and shock resistance:The pipeline has high flexibility, which can adapt to external deformation such as terrain settlement or earthquake, and reduce the risk of leakage.
Long life lawelawe:the design life can reach more than 50 makahiki, far more than the metal pipeline (usually 20-30 makahiki).
Hana maʻalahi: kaumaha māmā (wale nō 1/8 o ka paipu kila), support trenchless construction (such as directional drilling), greatly reduce installation costs.
Good sealing: using hot melt connection technology, the interface strength is consistent with the pipe body, and the potential gas leakage is eliminated.
Environmental safety:non-toxic and tasteless, in line with drinking water contact standards, a 100% hiki ke hana hou.
PE80: ʻO ka polyethylene haʻahaʻa haʻahaʻa, suitable for medium and low pressure gas transmission (≤0.4MPa).
PE100: Polyethylene kiʻekiʻe, with higher strength and pressure resistance (up to 1.0MPa), suitable for high pressure long distance transportation.

Applications of Black Polyethylene Gas Pipe
1. Urban gas network
Municipal gas main lines and residential pipelines.
Gas supply system for industrial and commercial users.
2. Industrial gas transmission
Industrial gas distribution for chemical plants, nā kahua mana, etc.
LNG/LPG storage and distribution station connection pipeline.
3 Rural and remote areas
Distributed gas supply system.
Bio-gas engineering gas pipeline.
4. Kaiapuni kūikawā
Earthquake prone areas: Use flexibility to reduce the risk of fracture.
Highly corrosive soil: Longer service life instead of metal pipes.
Water crossing: low buoyancy, excellent water pressure resistance.

FAQ of Black Polyethylene Gas Pipe
Q1: How long is the service life of PE gas pipe?
A: Under standard working pressure and environmental conditions, the design life of PE gas pipe is 50 makahiki. The actual life is affected by the installation quality, soil environment and maintenance.
Q2: Can PE pipe withstand high temperature?
A: PE gas pipe long-term operating temperature limit is +40℃, short-term (such as maintenance welding) can withstand +60℃. It is recommended to use heat-resistant materials or add insulation layer in high temperature environment.
Q3: How to connect PE gas pipe?
A: Electrofusion and Butt Fusion are mainly used, which need to be operated by professional technicians to ensure tightness.
Q4: Is the PEkinoea pipe environmentally friendly?
A: PE material is non-toxic and harmless, the production process is pollution-free, and can be 100% recycled, in line with EU RoHS and REACH environmental protection standards.
Q5: How to carry out pipe maintenance?
A: No special maintenance is required. It is recommended to carry out air tightness testing every 5 makahiki. Potential problems can be located through closed circuit television (CCTV) or acoustic detection technology.
