Welding Strueture: 
Steel plates, steel pipes,pipe fittings and flanges are welded to each other into special shaped steel structures and prefabricated parts.
WPS (Welding Proceture Specfrcation),MPS(Manufacturing Procedure Specification),.ITP (Inspecion Testing Plan),
WPQR (Welding Procedure Qualification Report),Fabrication Drawing, Welding Map.MTC(Mill Testing Certificate),NDT Report(UT RT PT),Coating Inspecion Report.Dimension Report etc.


Fabrication according to the drawing, all the welding seam required NDT testing, the complex structure increases the dificulity of the internal and external ant-corrosion coating. Each piece is wrapped in 100% scratch-proof and packed in the pallet
