Pipeline steel plays an important role in pipeline transportation. How many types of q355nh weather resistant steel, pipeline steel are there? At present, pipeline steel can be divided into the following four categories according to microstructure. First, pearlitic pipeline steel. The basic components of pearlitic pipeline steel are carbon and manganese, generally speaking, the content is 0.10% - 0.20%, and the manganese content is 1.30% - 1.70%. It is generally produced by hot rolling or normalizing heat treatment process. Second, acicular ferrite pipeline steel. Third, martensitic pipeline steel. Fourth, tempered sorbite pipeline steel.
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 q355nh weather resistant steel 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.
