Coil steel rolling of steel pipe

Cold-rolled steel coil method. Coil steel rolling direction and the same direction, the steel port is not allowed to use the hammer method and calibration tube bending curvature. Roll formed steel tube upright in a free state on the platform, with the model check the pipe curvature

Welding of steel pipe

Longitudinal seam steel X-shaped groove double-sided welding. The same section of pipe welded longitudinal seam submerged arc welding using, generally within the first welding seam, seam appearance inside pass the inspection, the use of carbon arc gouging back gouging treated after passing the outer weld seam. Butt weld test piece before soldering welding procedure qualification. Assessed according to product standards and design before the technical requirements for using steel grades, thickness, welding, welding material grades and groove type, formulation technology program. Its process solutions include beveling, assembly, cleaning, preheating temperature, interpass temperature and post-heating temperature and time, welding parameters, welding position, welding layers and channel number, the line energy range, weld stress relief heat treatment specifications and inspection, testing projects and programs.

Tone round of steel pipe

Round steel pipe tune on the platform at the right circle, using homemade rice-shaped tone tone round frame round. After adjusting circular symmetry of the pipe port to be supported to prevent pipe welding deformation when moving or lifting.

Cangzhou Shenlong pipe manufacture is a premier worldwide source for carbon steel pipe, stainless steel tube, seamless pipes, welded pipes,galvanized tubes,casing pipes and steel fittings.
