Certified Pipeline Welding & High-Integrity Pipe Spool Fabrication
High-pressure pipelines, metering stations, and terminal facilities demand flawless metallurgical bonding and precision fabrication. Lucama Engineering Services provides world-class welding and pipe fabrication services that strictly adhere to ASME Section IX, ASME B31.3, ASME B31.4, ASME B31.8, and API 1104 standards.
From shop fabrication of heavy-wall piping spools, pig launcher/receiver barrels, and manifold headers to precision field welding and in-service hot-tap tie-ins, our certified welding inspectors (CWI) and coded welders ensure 100% radiographic quality and metallurgical integrity on every weld.
Welding Capabilities & Custom Fabrication Scope
Our fabrication facilities and mobile field welding rigs handle complex geometries, extreme wall thicknesses, and specialized metallurgy:
Shop fabrication of ASME B31.3 / B31.4 pipe spools & skids
Mainline cross-country pipeline field welding (SMAW, GMAW, GTAW)
Pig launcher and receiver barrel fabrication & hydro-testing
Manifold headers, slug catchers & valve assembly fabrication
In-service welding & hot-tap branch connections (API 1104 App B)
Structural steel pipe supports, pipe racks, and skid frames
Exotic metallurgy welding: stainless steel, duplex, and chrome-moly
Preheat, post-weld heat treatment (PWHT), and hardness testing
Precision Metallurgy & Zero-Defect Standards
Our extensive library of qualified Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR) guarantees fast turnaround and zero-defect execution.
ASME & API Coded Procedures
In-Service "Hot-Tap" Welding
Controlled Shop Fabrication
We maintain over 80 pre-qualified WPS/PQR documents covering carbon steels up to API 5L X80, stainless steel alloys, and duplex grades, tailored for high-pressure sour gas and crude service.
- Qualified to ASME Section IX and API 1104 specifications
- Impact-tested weld procedures for low-temperature service
- Full metallurgical weld procedure verification and coupon testing
Welding on pressurized, flowing pipelines requires specialized thermal analysis to avoid burn-through and cold cracking. Our welders are specifically certified to API 1104 Appendix B with hydrogen-controlled consumables.
- Burn-through risk modeling and heat sink calculation
- Low-hydrogen electrode storage and temperature management
- Continuous pipe wall ultrasonic thickness and temperature monitoring
Our climate-controlled pipe fabrication facility features automated pipe rotators, submerged arc welding (SAW), and overhead cranage, producing modular piping spools ready for rapid field tie-in.
- Pipe spooling up to 48" diameter and heavy-wall schedules
- Precision CNC pipe profiling, beveling, and fitting
- Hydrostatic proof testing and internal blasting/coating before delivery

Frequently Asked Questions
What welding processes do your technicians utilize?
We utilize SMAW (Shielded Metal Arc Welding), GTAW/TIG (Gas Tungsten Arc Welding), GMAW/MIG (Gas Metal Arc Welding), FCAW (Flux-Cored Arc Welding), and SAW (Submerged Arc Welding) for shop spooling.
What testing is performed on completed pipeline welds?
All welds undergo visual inspection (VT) by certified CWIs, followed by volumetric non-destructive testing including Radiographic Testing (RT) or Phased Array Ultrasonic Testing (PAUT), plus MPI/DPI as required.
Do you provide complete fabrication data books?
Yes. Each spool or assembly is shipped with a comprehensive quality dossier containing Mill Test Reports (MTRs), WPS/PQR references, weld maps, NDT reports, PWHT charts, and hydro-test certificates.
Can you fabricate custom pig traps and manifolds?
Yes. We design, fabricate, and test custom pig launcher and receiver barrels with quick-opening closures (QOC), bypass piping, and kick-off valves engineered to ASME Section VIII and B31.4/B31.8.
