From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. GL-EH 40 higher strength steel, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
Tempering the important GL-EH 40 higher strength steel welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve GL-EH 40 higher strength steel strength, plasticity and toughness.
The Shipbuilding steel plate can be divided into general strength GL-EH 40 higher strength steel structural steel and high strength structural steel according to its minimum yield point strength level.BBN supplies and exports 3 types of ship steel, Ordinary Strength Steel Plate, High-tensile Strength Steel Plate and GL-EH 40 higher strength steel Extra High-tensile Strength Steel Plate. All steel plate product can be manufactured according to Society LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS, etc.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
