Stainless Steel Pipe
Feature: Stainless pipe manufacturer uses continuous formation process for OD<219mm thin-wall pipe application, and UOE process for OD>219mm thick-wall pipe application. The continuous formation process uses single or multi-torch (PAW+TIG) welding process. UOE is suitable for big diameter thick-wall pipe, length=6m approximately. Welding process: PAW, PAW+TIG, SAW, and various combinations for different thickness pipe applications Stainless pipes are comprehensively used in chemical, oil and gas, food, and papermaking industries etc. For high standard requirement of internal seam, internal seam refusing process is recommended UOE process application
- Pipe diameter: OD219~OD1,200mm
- Welding length: <6,000mm, option for customization
- Pipe thickness: 4~14mm
- Material: SUS321, SUS304, SUS316, SUS316L etc.
Welding Process and Feature For wall thickness above 4mm, the PAW keyhole process is used to achieve single-side welding double -side forming. And for wall thickness above 8mm, and beveling with root face for preparation, the PAW keyhole process is adopted for root pass, and the PAW/TIG/SAW process for capping; or even the PAW+TIG combination welding process applies.
