S690QL1 steel tubing, The wear-resistant steel plate adopts the open arc self-protection automatic surfacing process, and the composite-layer is a high-alloy wear-resistant layer with high hardness and high wear resistance on the surface of the ordinary steel plate or stainless steel plate. The wear-resistant steel plate has bimetal performance. That is, the high wear resistance of the working layer and the high plastic toughness of the base layer provide convenient mechanical connection and welding rod connection conditions for industrial applications, and can realize processing such as reeling, welding, plasma cutting, and mechanical connection.

We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the S690QL1 steel tubing steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.
