Customer Case Study:

A Middle Eastern EPC contractor required welded pipe spool assemblies and support structures for a gas processing facility expansion project. The project involved stainless steel piping, duplex steel support frames, and strict welding documentation requirements.

Our engineering team developed qualified welding procedures, optimized fabrication sequencing, and implemented comprehensive inspection controls throughout production. All assemblies underwent dimensional verification and non-destructive testing according to project specifications.

Following installation, the customer reported smooth site integration, reduced fit-up adjustments, and consistent weld quality across multiple project phases. The successful cooperation led to additional orders for modular skid structures and piping fabrication packages.

FAQ:

What is your minimum order quantity for Oil and Gas Welding?

We support both prototype and production orders. Whether you require a single fabricated assembly, a pilot project batch, or large-scale production, we can provide flexible manufacturing solutions.

What is the standard lead time?

Sample and prototype projects typically require 4-5 weeks. Production orders for Oil and Gas Welding components generally require 4–10 weeks depending on material availability, testing requirements, and project complexity.

Can you handle low-volume and project-based orders?

Yes. Many oil and gas projects require customized fabrication in limited quantities. Our production system is designed to support small-batch, project-driven, and recurring supply programs.

Which welding standards do you follow?

We operate requirements and welding procedures. Additional customer-specific standards can also be accommodated.

What inspection services are available?

We provide visual inspection (VT), dye penetrant testing (PT), magnetic particle testing (MT), ultrasonic testing (UT), radiographic testing (RT), dimensional inspection, and material certification review according to project specifications.

What documents can be supplied?

We can provide material certificates, welding records, WPS/PQR documentation, welder qualification records, inspection reports, NDT reports, and complete manufacturing data books when required.

How are products delivered?

We support EXW, FOB, CIF, DAP, and DDP shipping terms. Oil and Gas Welding assemblies can be delivered via sea freight, air freight, rail transport, or project cargo logistics depending on customer requirements and destination.

How do you ensure welding quality?

All Oil and Gas Welding projects are performed by certified welders using qualified welding procedures. Combined with material traceability, in-process inspections, NDT verification, and final quality audits, we ensure reliable weld performance for critical energy industry applications.
