Газавая труба ПНД, устойлівая да высокіх тэмператур

Увядзенне Газавая труба HDPE

Polyethylene Gas Pipe (PE gas pipe, short for PE gas pipe) is a pipeline system made of high density polyethylene (ПНД) або поліэтылен сярэдняй шчыльнасці (MDPE) as raw materials through extrusion molding process, specially designed for the transportation of natural gas, liquefied petroleum gas (LPG) and other gas media. У параўнанні з традыцыйнымі металічнымі трубамі, PE gas pipe has become the preferred material in the field of global gas transportation due to its characteristics of light weight, ўстойлівасць да карозіі, strong impact resistance and long life.

Падрабязная інфармацыя аб Газавая труба HDPE

Ўстойлівасць да карозіі: 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.

Доўгі тэрмін службы: the design life can reach more than 50 гадоў, far more than the metal pipeline (usually 20-30 гадоў).

Convenient construction: лёгкі вага (толькі 1/8 сталёвай трубы), support trenchless construction (such as directional drilling), greatly reduce installation costs.

Добрая герметызацыя: 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, і 100% перапрацоўваецца.

Тэхнічныя характарыстыкі Газавая труба HDPE

1.Material grading

PE80: Medium density polyethylene, suitable for medium and low pressure gas transmission (≤0.4MPa).

PE100: Поліэтылен высокай шчыльнасці, with higher strength and pressure resistance (up to 1.0MPa), suitable for high pressure long distance transportation.

2. Pipe size

Заўвага: SDR (Стандартнае суадносіны памераў) is the ratio of the outer diameter of the pipe to the wall thickness, and the smaller the value, the stronger the pressure resistance.

3. Standard length

Straight pipe: 6m, 12m (non-standard length can be customized).

Coil pipe: 50m-200m (suitable for small diameter pipe, easy to transport and construction).

4. Color identification

Black pipe body + yellow stripe: international common gas pipeline identification.

Other colors can be customized according to customer requirements (subject to local regulations).

5. International standard certification:

ISO 4437: International standard for buried polyethylene piping systems for gas applications.

У 1555: European standard for polyethylene piping for gas transmission.

ASTM D2513: American Society for Materials and Testing Standard for Gas Piping.

GB 15558.1-2015: China’s National Standard for polyethylene pipes for Gas use.
