Good SA633 Gr C carbon steel plate sheet quality can lengthen its service life

Q345B material is a low-carbon alloy steel (c <0.20%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa. It has good comprehensive mechanical properties and technological performance. In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness.

The company specializes in the research and development, production and sales of SA633 Gr C carbon steel plate sheet seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has SA633 Gr C carbon steel plate sheet five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,SA633 Gr C carbon steel plate sheet rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of SA633 Gr C carbon steel plate sheet welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.

API 5L X65 steel plate/pipes, under API 5L standard, we can regard X65 steel plate/pipes as large diameter pipes. SA633 Gr C carbon steel plate sheet, X65 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X65 steel pipes/plate is a higher strength, tough, weldable steel for applications in the oil and gas industry.X65 Flange Steel meets fully the mechanical property requirements of the API 5LX X65 line pipe specifications whilst maintaining a high degree of toughness and weldability.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
