(X T-pipe steel grade, the 245R T-pipe, 304 T-pipe) 
 Hebei ten billion mainly the production of gas, petroleum, petrochemical, boiler, chemical industry, high pressure high temperature, pressure piping tube with T-weld volume, the volume all through the X-ray 100% flaw qualified to GB 9711 standard, to withstand the fluid pressure of steel pipes hydraulic pressure test should be carried out to test the pressure capacity and quality, and leak under pressure, wet or expansion of qualified, some steel pipe but also according to the requirements of the standard or the demand side, curling test, flaring test, the pressure flat test. 
 T-pipe is hot rolled coil to coil deformation sleek cylindrical welded together using a welding process after forming machines. Longitudinal is a common pipe, the gas pipeline with a diameter greater than 426mm (or 508mm) pipe generally known as a T-pipe, LSAW pipe and straight seam welding in accordance with the welded into a tube, can be divided into tube two kinds. High-frequency current skin effect and proximity effect or flux layer burning arc welding, the tube edge of the heating and melting and fusion, the final cooling effect of the extrusion pressure molding. T-shaped pipe welding technology processing, welding in accordance with certain technical parameters and methods, and strictly control the quality and temperature, to ensure that the T-shaped pipe after the welding has good use of the value and role in welding. 
 Addition should meet the requirements, container manufacturing, inspection and acceptance of the T-shaped pipe, but also meet the design requirements to ensure compliance with certain quality standards in accordance with the requirements of specifications and welding in the figure. T-pipe container manufacturing units should have a quality system requirements in line with the relevant laws and regulations of national pressure vessel safety supervision institutions or the quality assurance system and production equipment in line with national criteria for acceptance, the use of advanced manufacturing process is made, with excellent quality and performance guarantee good performance and value in the use and production of T-shaped pipe. T-welding of the pipe container should hold the appropriate category of the "Boiler and Pressure Vessel Welder Certificate of Competency" officers. Boiler and Pressure Vessel NDT personnel qualification certificate "of the non-destructive testing of the T-pipe container should hold the appropriate method" officers. 
 Of welded joints of the pressure part of the T-pipe container divided into A, B, C, D, four types of T-shaped pipe in use, and welding technology to have some control factors, in strict accordance with the appropriate factors and methods of control to ensure that T pipe good role and value in use.
