API 5L-D three layers of polyethylene (3PE) anti-corrosion steel pipe for oil and natural-gas industry.

Coating standard: DIN30670

Size:outside diameter from 159mm to 1220mm.

Applied range: 3PE steel pipe can be widely used in gas, oil, chemical, mine, power, thermodynamics and water industries for transportation; meanwhile, can be used for bridge pipeline, outside surface coated with 3PE and inside surface could be coated with epoxy resin powder then decrease transportation resistance.

3LPE Coating Pipe

3LPE coating pipe with good corrosion resistance, moisture permeability resistance and mechanical properties, is widely used in the oil pipeline industry. But this kind of anti-corrosive coating steel pipe is easy to happen edge warping problems due to corrosion. So, this problem should be paid much attention on.

3PE steel pipe can be widely used in gas, oil, chemical, mine, power, thermodynamics and water industries for transportation; meanwhile, can be used for bridge pipeline, outside surface coated with 3PE and inside surface could be coated with epoxy resin powder then decrease transportation resistance.

East Steel Pipe is the world’s leading provider of 3LPE pipe, also known as 3lpe coating pipe. The coated pipes are composed of three functional components: a high performance fusion bonded epoxy (FBE), followed by a copolymer adhesive and an outer layer of polyethylene which provides tough and durable protection.

Oil Steel Pipe

Oil steel pipe is mainly used to connect the drill collar and bit and drilling. Oil steel pipe is mainly used in the drilling process and after the completion of borehole wall support, to ensure that the drilling process and after completion of the normal operation of the oil wells.
