High pressure pipe is a kind of carbon steel pipe, which is specially applied in boiler in power plant, etc. The production process as follows:
Raw material Test→ Uncoiling → Strip leveling →End Cutting → End Shearing and Welding → Accumlator → Forming →Telepathy Welding →Seam Heat Treatment →                              Air/Water Cooling → Body/Seam UT →Sizing Straightening → Cutting → Visual and Dimension Inspection →Hydraulic Test→ End Beveling →Flatten Test→ Seam/End UT →Length-Measuring and Weighing →Coating-Marking → Storage

Manufacuring standard
Outer Diameter: 21.3mm-----630mm
Wall Thickness: 1.5mm----14mm
Length: 5m-----18 m

Application
High pressure pipe is a kind of carbon steel pipe, which is specially applied in boiler in power plant, etc.  The material of this kind of pipe can endure high-pressure environment. And they also meet the requirement special chemical environment so that work smoothly.
