The strict quality control of p235gh pipe processing

P275NH normalizing can weld refined grain steel. Fine grain steel P235GH pipeis understood to be steel with ferrite grain size of 6 or finer after testing according to EURONORM103 standard. Executive standard: EN10028-3, number: 1.0487. P275NH is non-alloy quality steel for pressure equipment. P275NH steel plate has good plasticity, toughness, cold bending performance and welding performance.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating p235gh pipe production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like p235gh pipe, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for p235gh pipe and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our p235gh pipe service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's p235gh pipe customer service to establish a good, comprehensive, full service system.
