After the quenching and tempering treatment of seamless pipes, the parts produced have good comprehensive mechanical properties and are widely used in various important structural parts, especially those connecting rods, bolts, gears and shafts that work under alternating loads. But the surface hardness is low and not wear-resistant. Tempering + surface quenching can be used to improve the surface hardness of parts. Its chemical composition contains carbon (C) content of 0.42~0.50%, Si content of 0.17~0.37%, Mn content of 0.50~0.80%, and Cr content<=0.25%. Recommended heat treatment temperature: normalizing 850°C, quenching 840°C, tempering 600°C. Common seamless steel pipes are generally made of high-quality carbon structural steel, which is not very hard and easy to cut. It is often used in molds to make templates, tips, guide posts, etc., but heat treatment is required. 1. After quenching and before tempering, the hardness of the steel is greater than HRC55, which is qualified. T...

At the end of October 2021, Tianjin Xinyue received the inquiry of high-frequency straight welded pipe from regular customers in Australia. The product specification is AS1163 C350 dn100-dn600, the wall thickness is 4.8/6.4/9.5mm, the length is 9 / 12M, a total of 11 specifications and 100 tons Product specifications are the most popular and most popular in the Australian market, but for our domestic factories, whether it is material, unconventional wall thickness and 9-meter single length requirements, they need to be customized separately, which means that there is a minimum order quantity requirement for any specification of the order, 50 tons / size.

In end of October, 2021，a regular Japanese client informed Xinyue Steel Group that a batch of new wells were about to be constructed, and hoped that Xinyue could support it as always. The requirement for the pipe is as same as last year. The size of the pipe is 89.1*4.5*4000mm. Both ends of the pipe need to be welded with a flange to connect the water pipe to the well. Since the ports of the water well are not particularly large, in order to avoid the angle deviation after the pipes are connected and scrape to the well wall, the tolerance control of the pipes and flanges becomes very strict, and the welding process also has higher requirements. After the customer confirmed the order, Xinyue carried out strict quality control from every production step. After the production of the tube, Xinyue first made a detailed measurement of the size. After confirming that the tolerance of the size was fully up to the standard, Xinyue measured the straightness of the tube and confirmed that there w...
