Pipe Fabrication Services — ASME B31.1 / B31.3

Service · Pipe Fabrication

Pipe joined into systems — precisely to your design.

Pipe fabrication is the process of joining piping materials such as pipe, elbows, tees, reducers and flanges into specialized piping systems, built precisely in line with the design specifications and isometric drawings supplied by our customers.

We deal in all types of industrial piping — process piping, utility piping, hydraulics and bulk conveying — built from carbon steel, stainless steel, alloys, plastics, fiberglass and ductile. Whether it's a new-construction package or a repair to an existing system, our shop turns drawings into tested, code-compliant assemblies.

Capabilities

What our fabrication service covers

Drawing & Iso Review

We work from your isometrics and P&IDs, building bills of material and weld maps before a single cut is made.

Cutting & Beveling

Precision cutting, machining and end-prep to ensure consistent fit-up and full-penetration welds.

Multi-Process Welding

SMAW, GTAW, GMAW and FCAW performed by ASME Section IX–qualified welders.

Heat Treatment

Post-weld heat treatment and stress relief where the code or material requires it.

Inspection & NDT

Visual, RT, UT, MT and PT examination coordinated to the governing acceptance criteria.

Delivery & Install

Tagged, documented assemblies delivered ready for field bolt-up — or installed by our crews.

Materials & Ranges

Built in the alloy your service demands.

Pipe sizes	½" to 60" nominal bore
Carbon steel	Process, utility & high-pressure
Stainless steel	300 & 400 series, sanitary & process
Alloys	Duplex, titanium, cupro-nickel, Inconel
Non-metallic	Plastics, fiberglass & ductile
Welding processes	SMAW · GTAW · GMAW · FCAW

Codes & Standards

Fabricated to the code that governs your job.

We qualify procedures and welders to ASME Section IX and fabricate in accordance with the applicable piping and welding codes:

ASME B31.1 — Power Piping ASME B31.3 — Process Piping ASME B31.4 — Pipelines API 1104 ASME Sec. IX

Every assembly ships with the documentation your QA team needs — material test reports, weld maps, NDT results and hydro records.

FAQ

Pipe fabrication questions

Shop fabrication is performed in a controlled environment with optimized positioning, fixturing and inspection access — which generally yields higher weld quality, faster throughput and lower cost. We maximize shop fabrication and minimize field welds to keep installations efficient.

It depends on the service. Power and steam systems typically fall under ASME B31.1, chemical and process plants under ASME B31.3, and liquid pipelines under ASME B31.4. We'll confirm the governing code with your engineer and qualify procedures accordingly.

Yes. Beyond carbon and stainless steel we routinely weld duplex and super-duplex, titanium, cupro-nickel and Inconel — each with the appropriate purge, filler and procedure to protect the metallurgy.

Always. Material traceability (MTRs), WPS/PQR records, NDT reports and hydro-test records are compiled into a turnover package for your records and your client's QA team.
