| APPLICATION | Widely used in large quantities for a variety of heating, refrigeration, oil, steam other pipelines. A large number for a variety of heating, refrigeration, oil, steam other pipelines |
| STANDARD | API 5L, API 5CT, SY/T5037, SY/T5040, GB/T9711.1, ASTM A53,EN 10219,EN10217,JIS G3444 |
| SUBSTRATE | 2pe/3pe/FBE/IPN8710/epoxy coal tar/HDPE coating anti-corrosion spiral steel pipe |
| oUT DIAMETER | 159MM~3200MM |
| WALL THICKNESS | 3MM~30MM |
| LENGTH | 5.8M~-25M ACCORDING TO CUSTOMER'S REQUIREMENTS |
| FIRST LAYER | Fusion bonded epoxy, which thickness is larger than 100μm. ( Thickness of FBE coated ＞100μm ） |
| SECOND LAYER | Adhesive layer. It is binding epoxy PE layers. ( Thickness of second layer: 170~250μm) |
| THIRD LAYER | PE layers. Thickness is 2.5 mm to 3.7 mm. It is polyethylene which has advantages to anti-water, electrical resistance, anti mechanical damage. It is a very important layer. |
| corrosion resistance | The elements of PE structure stability is high. So we can use it to prevent corrosion natural gas, liquefied petroleum gas, artificial gas, other chemical subjects. it needno secondary anti-corrosion equipment. The chemical of soil does produce any effects on the steel pipe using 3LPE coating. |
outstanding wear resistance | Tests show that PE pipe’s wear resistance is 4 times than bare steel pipe. Especially transporting mud, compared with varnished steel pipe, PE coated pipe has better performance of wear resistance. 3PE has a smooth surface, its manning coefficient is 0.009. |
| durable life time | 3PE coated steel pipe can prolong above 50 years. It is because 3PE coating has good stability anti-aging performances under normal work temperature pressure conditions. |
| corrosion resistance | The elements of PE structure stability is high. So we can use it to prevent corrosion natural gas, liquefied petroleum gas, artificial gas, other chemical subjects. it needs no secondary anti-corrosion equipment. The chemical of soil does produce any effects on the steel pipe using 3LPE coating. |
| flexibility | 3PE coating is a kind of soft flexible material, it breaks after prolong 5 times longer. It is easy to bend without damage. 3PE coating steel pipe can bypass steel pipe redue the fees of installation. |
excellent resistance of impact & earthquake | One of the important features of 3LPE coating is that 3pe is fragile under low temperat-ures. The temperature at the range of -60℃~60℃ is safe. So it can adapt to going down of pipeline work in winter. 3PE pipeline won’t easily to break due to its good impact performances. |
This cheap anti-corrosion process is generally accepted all over the world. 3PE can strengthen the pipeline’s mechanical properties, high electrical resistance, waterproof, wearable, anti-aging. It could protect the pipe the heat loss which only accounts for 1/4 of pipe.
