]]> These are seamless pipes. Material is API 5L Grade B. Size is 8″ Sch40. Length is 12m.  2PE coating, thickness is 2.7mm. PE standard is DIN30670.  This is the first time that Solomon client buys PE seamless pipes from China. They feel good after visited steel pipe and PE lining factories.  The pipes and PE coating are very pretty and beyond their imagination.

Surface—3PE Pipe

3PE Coating is prevalent in pipe system for oil, gas water and other fluids. It includs 3 layer coatings.

  • First is FBE Coating. It is a fusion bonded epoxy, the thickenss should be larger than 100μm. (FBE＞100μm）
  • The second layer is adhesive. The function is binding the first the third layer. The thickness is between 170 to 250μm. (AD: 170~250μm)
  • The third layer is PE. PE is polyethylene.

This coating can help strengthen the mechanical properties of pipeline. So 3PE Pipes have good resistance to water, electrical, mechanical damage, aging and wear.
