Seamless steel alloy steel pipe

　　Alloy steel seamless pipe is a kind of seamless steel pipe, its performance much higher than the general seamless steel pipe, because it containing higher Cr with high temperature and low temperature resistance, corrosion resistance, so the alloy pipe widely used in petroleum, chemical, electric power, boiler and other industries

　　Alloy tube material

　　12Cr1MoV, P22 (10CrMo910) T91, P91, P9, T9, WB36, Cr5Mo (P5, STFA25, T5,) 15CrMo (P11, P12, STFA22), 13CrMo44, Cr5Mo, 15CrMo, 25CrMo, 30CrMo, 40CrMo.

Difference between water supply and drainage pipelines and industrial pipelines

    1, Water supply and drainage     Building water supply systems can be divided into living, production, and fire-fighting water supply systems depending on their applications. These three water supply systems are not necessarily set up separately, and are often a combination of both or three. The building drainage system collects the water used by people inside the building in daily life and industrial production, and discharges it outdoors in time.     According to the nature of the sewage discharged from the system, the internal drainage of the building can be divided into domestic sewage, domestic wastewater, industrial wastewater, and roofing. Rainwater, domestic sewage (waste) water, industrial waste water, and rainwater are each set to discharge pipelines, which are called diversion systems; the combination of more than two types in one pipeline is called combined flow system; what kind of form should be used according to water quality conditio...

Xinyue supports pressure piping projects for regular customers

Project location：Middle East Product：Spools (Short pipes&fittings welded with double flanges) Specifications：OD 114-813MM, WT 6-17MM, L 800-4200MM Standard and material：Pipes in ASTM A53 GRB; Fittings in B16.9 ASTM A234 WPB; Flanges in EN1092-1 ASTM A105; Welded in standard API 1104 Hydro test in EN13480-5 Usage：Pressure Liquid Pipeline project Inquiry time：2022.03.02 Order time：2022.07.20 Shipping time：2022.09.22 Estimated arrival time：2022.10.28 This order is still from a regular client. The client has been purchasing SMLS&LSAW&SSAW steel pipes from Xinyue for 4 years. After reading the project list and spool project supply record of Xinyue, the customer knew that Xinyue had its own welding and coating processing line this year, so he immediately sent an inquiry to Xinyue after having an spool inquiry. As expected, Xinyue gave the customer the best price and shipping schedule solution, and made 13 sets of drawings for customers and terminals to refer to. With the help of ...

Methods for non-destructive testing of seamless steel tubes

 Non-destructive testing refers to the inspection methods used to inspect the internal or surface defects of the material, or to determine some physical quantities, properties, and organizational states of the material without destroying the original state and chemical properties of the material to be tested. There are four commonly used non-destructive testing methods for seamless tubes: 1. X-ray inspection Suitable for detecting internal defects in metals, non-metals or other materials. The energy of the light quantum of X-ray is much greater than that of visible light, it can penetrate objects that visible light cannot penetrate, and while penetrating objects, it will have complex physical and chemical interactions with matter, which can ionize atoms and cause certain substances to emit light. Fluorescence can also cause photochemical reactions in certain substances. If there is a defect in the local area of the workpiece, it will change the attenuation of the object to the ray ...
