API 5L PSL2 Gr.B pipeline steel has good welding performance  Good weldability of API 5L PSL2 Gr.B pipeline steel   is very important to ensure the integrity of pipeline and field welding quality.One of the most remarkable features of the development of API 5L PSL2 Gr.B pipeline steel  in modern times is the continuous reduction of carbon content in steel. Adding trace titanium can restrain the toughness drop in the affected area and improve the API 5L PSL2 Gr.B pipeline steel welding performance.  The difficulty and emphasis is on high resilience. With the continuous development of oil and natural gas transportation, the requirements for the performance of oil API 5L PSL2 Gr.B pipeline steel are constantly improved, especially for the toughness. The improvement of these properties requires the content of impurity elements C, S, P, O, N and H in API 5L PSL2 Gr.B pipeline steel...

The Straightening of Corten B channel steel To straighten out the bend and shape of Corten B channel steel in rolling, cold, transport, etc., to make the shape correct and straight by straightening so that meet the Corten B channel steel  quality requirements. There are some reasons to impact the straighten of Corten B channel steel. Effect of straightening equipment on quality of  Corten B channel steel . Corten B channel steel straightening generally use 7-roll to 11-roll roller straightening machine. Small Corten B channel steel  using more rolls straightening machine; The roller straightening quality is good, and the roller straightening for large Corten B channel steel is complicated, so it is often used in seven-roll straightener. Effect of straightening technology on quality of Corten B channel steel . Because the Corten B channel steel is an asymmetrical rolled piece, the temperature is low in the thinner part of the...
