How to cut 3PE anticorrosion steel pipe ?

In the installation of 3PE anti-corrosion steel pipe In the early stage does not have the length of the plan, such as 3pe anti-corrosion pipe routine is 12 meters. But sometimes in some parts of the project need is 3 meters, this time need to 3pe anti-corrosion steel pipe cutting. What is the  3pe anticorrosion pipe? 3PE anticorrosive pipe parent metal include seamless steel pipe, spiral steel pipe and straight seam steel pipe.Three layers structure of polyethylene (PE) anticorrosive coatings with good corrosion resistance, resistance to moisture permeability and mechanical properties, is widely used in the oil pipeline industry. So […]

API 5L ERW pipe ultrasonic flaw detection principle

Ultrasonic flaw detection principle of API API 5l ERW pipe Ultrasonic flaw detection is the necessary process of API 5l ERW welded pipe production. API-5L Standard and the API-5CT Standard stipulates: All for the oil casing and the conveying pipe electric welded pipe, its tube body, the tube end, the weld seam all must carry on the nondestructive testing. The existing welded pipe units in China are basically equipped with ultrasonic flaw detection. ERW Welded Steel Pipe by API 5L Standard Welding manner: ERW, LSAW Welding seam status: heat treatment End processing: plain end, bevel end, plastic end cap. ERW […]
