The X80M pipeline steel customized by the company for customers will be supplied to a construction machinery manufacturing enterprise for making core components of rotary drilling rigs. Based on the original production process of high-end A572 Gr 50 high strength steel pipeline steel, the company formulated and optimized the process plan and production operation plan, strictly controlled the content of harmful elements in the production, optimized the rolling parameters and cooling mode, and ensured that all performance indexes of customized X80M A572 Gr 50 high strength steel pipeline steel met the requirements of customers.
As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.
In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe A572 Gr 50 high strength steel for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A572 Gr 50 high strength steel steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A572 Gr 50 high strength steel method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
Our SA516Gr70 pressure vessel plate has good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. The product has good dimensional tolerance and surface quality. China made A572 Gr 50 high strength steel steel plates are now widely used in major chemical sites.
