How to control the api 5l x70 steel quality

Standard:API 5L PSL1|PSL2.
Scope:API 5L is generally refers to the standards of pipeline steel, include pipeline pipe and pipeline steel plate.
API 5L line pipe steel grade levels:GR. B, X42, X46 and X52, X56, X60, X70 and X80.
Details

ASTM A106 pipe is the standard specification for seamless carbon api 5l X70 steel steel pipe for high-temperature service. Applications are transport gasses or fluids in refineries and boiler plant bearing high temperatures and pressures. Pipe produced according to api 5l X70 steel ASTM A106 shall be suitable for bending, flanging, welding and other forming operations.

Chromium element (Cr element) can improve the strength and hardness of api 5l X70 steel, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel api 5l X70 steel surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
