Seamless Steel Pipe

 According to our sales experience, we repeatedly faces new customers’ feedback that SMLS pipe processing qualified rate is low, waste tools and other problems. Bright tube (cold tube) is difficult to cut, cost cutting tool machine, annealed tube is sticking knife during processing, of poor finish degree and surface quality is not good. Today we will briefly introduce which kind of SMLS pipe is most suitable for your usage. Bright pipe (cold forming) Only processing of the inner hole and have high requirement to the material surface, considering the cost, we suggest the customer to use the bright pipe, because the it has good brittleness, easy to processing, mainly for low carbon steel. However, compared with the annealing pipe, the bright pipe has higher hardness and brittleness, easy to damage the lathe tool. The annealing pipe Annealing is mainly to remove the residual stress on the surface of seamless steel pipe, reducing the mechanical properties and improving the ductility. H...

 In May 2020, the pipe fittings and pipes ordered by South American customers were successfully shipped, including large-diameter elbows, large and reduction and flanges, pipes and other products. Among them, the diameter of the elbow is 52 inches, 5D, and the volume is large. The flanges are 72 inches and 52 inches. The size is also very special.

 Seamless steel pipe (SMLS pipe) cracks reasons: 1. Raw material factors Inferior tube blanks will have internal and external warping, scars, cracks, etc.; 2. Temperature factor The first important process in the production of seamless steel pipes is heating. Poor heating (unevenness, insufficient temperature, etc.) will cause inner warping, etc.; 3. Equipment factors From the beginning of the furnace, every equipment component will affect the final quality of the pipe. For example, the scratching of equipment parts will cause the outer skin and pits; the failure of entering the piercing machine will cause the head of the tube blank to be exposed to water and it will be difficult to bite or the inner skin of the head will be warped; 4. Process issues The process issues are also quite complex, including adjustment issues, equipment failure issues, and pipe quality issues caused by the wear of process components (plugs, guide plates, rolls, etc.). 5. It may also be a problem of trans...

On May 10th, all cargo of 1200MT DN400 18meter ERW pipes has been successfully shipped from Tianjin port to Australia. This cargo is the 1st stage of local water pipeline project, has included PSL2 X42 ERW steel pipes and relevant high steel grade flanges & bends & bolts & nuts over 100 items. Client nominated third party inspection to monitor the whole production process from raw material arrival, including 100% hydrostatic testing & UT testing process. Due to our domestic demands recovered from the pandemic, we met the peak season of feed material production. Material only arrived to mill before our labor holiday. During the Labor holiday, our production team & inspection team still worked overtime to catch up the earliest bulk shipment as client’s request. Finally all the production & finished products well passed the third party inspection, and client received the perfect QA report. Client also expressed high recognition and appreciation for Xinyue's pro...
