DSS Pipe Welding Equipment with Purging System supplier & Exporter
XPRO Impex is a leading DSS pipe welding equipment supplier and exporter in India. We specialise in duplex stainless steel pipeline welding solutions with integrated argon purging systems, ensuring oxide-free, high-integrity weld roots that meet the most demanding international pipeline standards.
Our DSS pipe welding equipment with purging is engineered specifically for argon arc welding of duplex and super-duplex stainless steel pipes used in oil & gas, offshore, chemical and subsea pipeline construction. Each unit undergoes rigorous quality checks to ensure leak-free purging performance and precision pipe alignment.
Internal Pipe Pneumatic Clamp with Purging
Pneumatic internal pipe clamp with integrated argon gas purging system for DSS argon arc welding. Ensures oxide-free weld root quality on duplex stainless steel pipelines.
Internal Pipe Hydraulic Clamp with Purging
Heavy-duty hydraulic internal pipe clamp with argon purging for large-diameter DSS pipelines. Provides maximum clamping force with integrated back-purge gas distribution.
External Pipe Mechanical Clamp (For DSS Argon Welding)
Specialised external mechanical clamp designed for DSS argon arc welding. Provides precise pipe alignment while the integrated purge channel maintains an argon-rich environment at the weld root.
Internal Purging Preventing System
Standalone internal argon purging prevention system with inflatable dam discs that create a sealed argon-filled zone around the weld joint, preventing oxidation throughout the complete DSS pipe weld process.
How the Argon Purging Process Works
1. Clamp & Seal
Internal or external clamp is positioned and locked to align the DSS pipe joint with zero gap tolerance.
2. Purge with Argon
Argon gas is introduced through the purge port, displacing all oxygen from the pipe bore weld zone.
3. Weld Root Pass
TIG root pass is deposited under continuous argon protection, achieving a bright, oxide-free weld root.
4. Inspect & Complete
Weld root is visually inspected, clamp released, and fill passes completed per the welding procedure.
Oxide-Free Root
Argon back-purging ensures zero oxidation at the weld root critical for DSS corrosion resistance.
Leak-Free Seals
High-grade inflatable seals maintain argon atmosphere throughout the complete weld cycle.
