As the thickness and hardness of API5L L480 PSL1 pipeline steel increase, the tendency to crack at the cutting edge increases. In order to prevent the API5L L480 PSL1 pipeline steel from cutting cracks, preheating should be carried out before API5L L480 PSL1 pipeline steel cutting. Special attention should be paid to preheating to make the entire API5L L480 PSL1 pipeline steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole API5L L480 PSL1 pipeline steel cannot be preheated, the partial preheating method can be used instead.
Q355NH material has a protective rust layer that resists atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers, etc. It can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
We can process the steel materials according to your drawing. Or if you can not make drawing, please send us API5L L480 PSL1 pipeline steel specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.
