Stainless Steel Pipe Welding - Case Study

Case Study Overview

Karl Dungs, a renowned manufacturer of combustion control systems, required high-precision stainless steel pipe assemblies for their advanced gas valve systems. The components needed to meet stringent specifications to ensure safety, reliability, and compliance with industry standards.

Karl Dungs Ltd – Leading provider of combustion control systems for industrial and commercial gas applications.

Sector:

Industrial Gas & Combustion Engineering

Project Scope:

Karl Dungs required precision welding on a series of stainless steel pipe assemblies used in high-performance gas control systems. The brief called for clean, high-penetration welds with consistent quality throughout multiple units, while maintaining the structural integrity and flow characteristics of the internal pipework.

  • Welding thick-walled stainless steel elbows with tight tolerances
  • Maintaining clean, even weld beads across curved joints
  • Avoiding distortion and internal oxidation in a highly visible and flow-sensitive application
  • Meeting ISO 9606-1 coded standards for stainless TIG welding
  • Repeatability across multiple assemblies
  • Weld Process: TIG welding with precise control over heat input and travel speed
  • Joint Prep: Careful bevel prep and purge setup to ensure full penetration and internal cleanliness
  • Execution: Welded using coded procedures by our in-house specialists, with full traceability
  • Inspection: Visual and dimensional checks on every part, with client sign-off prior to dispatch
  • Delivered multiple high-spec welded pipe assemblies on time
  • Zero defects, clean surface finish, and perfect arc stability across welds
  • Client praised our weld quality and consistency, leading to further enquiries for future batches

Client Feedback:

“Welds were spot-on — clean, consistent, and exactly what we needed. Leanfabs handled the job professionally and delivered on time.”
