ASME-Certified Fabrication for the Energy Sector
Pressure Vessels · Piping Assemblies · Modular Skid Packages — Built to Code, Verified In-House
Wikota’s fabrication facility in Brookshire, Texas produces code-compliant pressure equipment, piping systems, and modular assemblies for clients across the hydrocarbon and energy industries. As an ASME-certified shop with in-house Certified Welding Inspectors and NACE-certified personnel, we maintain direct control over quality from first cut to final hydrostatic test—not through secondhand vendor reports, but through our own people on our own shop floor.
Our fabrication capabilities are fully integrated with Wikota’s engineering and construction services. That means the equipment we build is designed by engineers who understand our shop’s capabilities, and installed by construction teams who were involved from the start. This tight coordination eliminates the fit-up problems, documentation gaps, and schedule conflicts that are common when fabrication is outsourced to a disconnected third party.
We ship completed projects anywhere in the United States.
What We Fabricate
Our Houston facility is equipped to handle a wide range of energy sector fabrication requirements, from individual pressure components to fully assembled, tested, and documented modular systems ready for field installation.
Piping Fabrication
Wikota delivers custom piping solutions engineered for the demands of high-pressure, high-temperature, and corrosive-service environments found across oil and gas, petrochemical, and power generation applications. Our piping fabrication services encompass cutting, bending, welding, fit-up, and full assembly—executed to project-specific specifications and code requirements. Every spool piece and assembly is fabricated with dimensional accuracy that minimizes field rework and accelerates installation timelines.
Skid Fabrication
Our modular skid packages integrate process equipment, piping, instrumentation, and controls onto a single transportable platform—engineered, assembled, and tested in our shop before shipping to your site. This approach compresses construction schedules, reduces field labor, and allows system-level testing in a controlled environment. We build skids for applications including process systems, metering, pumping, chemical injection, gas compression, H₂S removal, and biogas upgrading.
Pressure Vessels & Process Equipment
Wikota fabricates ASME-stamped pressure vessels and process equipment designed for the operating conditions and service requirements of your specific application. Our capabilities cover a range of vessel types, sizes, and materials—manufactured under our quality management system with full material traceability, documented welding procedures, and code-required inspection and testing.
Custom Packages & Assemblies
Beyond standard fabrication categories, we build custom packages and assemblies that combine multiple components into integrated, field-ready systems. From renewable natural gas clean-up skids to compression packages and cryogenic system components, Wikota’s fab shop adapts to the unique demands of each project scope.
Welding Processes & Expertise
The integrity of every piece of fabricated equipment depends on the quality of its welds. Wikota employs multiple welding processes to match the right technique to each application, material, and code requirement. Our certified welders are qualified across a range of processes and positions, with performance qualifications documented and maintained per ASME Section IX.
GMAW (MIG) — High deposition rates for efficient production welding on carbon steel and stainless steel components. Ideal for structural elements, skid frames, and high-volume piping fabrication.
GTAW (TIG) — Precision welding for critical joints, thin-wall piping, root passes on pressure components, and applications requiring superior weld quality and appearance. Essential for stainless steel, chrome-moly, and exotic alloy work.
Flux Cored Arc Welding (FCAW) — Versatile process well-suited for heavy fabrication, structural work, and applications requiring high deposition in all positions.
Shielded Metal Arc Welding (SMAW) — Field-proven process for maintenance, repair, and applications in challenging positions or environments where other processes are impractical.
Each welding procedure specification (WPS) is backed by documented procedure qualification records (PQR) and verified by our in-house CWI team before production welding begins.
Quality Assurance & Compliance
Quality is not an add-on at Wikota—it’s embedded in every stage of our fabrication process. From incoming material verification through final documentation packages, our quality management system ensures that what we deliver meets code requirements, client specifications, and our own internal standards.
Certifications & Standards
Wikota’s fab shop operates under ASME certification for pressure vessel fabrication and adheres to applicable API (American Petroleum Institute), AWS (American Welding Society), and jurisdictional standards. Our quality management system is documented in comprehensive QA/QC and HSSE manuals that govern every aspect of shop operations.
Testing & Examination
Wikota performs hydrostatic testing and coordinates all required non-destructive testing (NDT)—including radiographic, ultrasonic, magnetic particle, and liquid penetrant examination—to verify the integrity of pressure-retaining welds and components. Testing procedures are developed to meet applicable code and project-specific requirements, with results documented and included in final turnover packages.
Documentation & Traceability
Every project leaves our shop with a complete documentation package, including material test reports (MTRs), welding procedure specifications (WPS), welder qualification records, inspection reports, test results, and as-built drawings. Full material traceability from heat number to installed location is maintained throughout fabrication—providing the audit trail that code compliance and client quality requirements demand.
Fabrication Integrated with Engineering and Construction
Because Wikota's fab shop operates under the same management as our engineering and construction teams, your project benefits from coordinated design, production, and installation—with one team accountable for the result.

Part of a Larger Delivery System Most standalone fab shops build what they’re told to build, without visibility into engineering intent or construction sequence. At Wikota, fabrication is one pillar of an integrated EPC delivery model. Our engineers design with shop capabilities and field constructibility in mind, and our construction team plans installation around actual shop production schedules—not assumptions. The result is equipment that fits, documentation that’s complete, and delivery that aligns with your project timeline.
Direct Quality Ownership When an EPC firm subcontracts fabrication, quality oversight is indirect at best. Wikota owns and operates its shop. Our quality team, our welders, our inspectors, our procedures. There’s no disconnect between the team that committed to your specifications and the team executing the work.
Right-Sized Capacity We’re not a mega-shop quoting 18-month lead times, and we’re not a two-man operation stretching beyond capability. Wikota’s facility and workforce are scaled to deliver the custom pressure equipment, piping systems, and modular packages that energy sector projects require—with the responsiveness and senior-level attention that large-volume shops can’t provide.
Ship-Ready for North America Our Brookshire, Texas location provides direct access to Gulf Coast transportation infrastructure. We ship completed, tested, and documented fabricated projects anywhere in the continental United States, with packaging and logistics coordination included.
Frequently Asked Questions — ASME-Certified Fabrication
ASME certification means our fabrication facility has been audited and authorized by the American Society of Mechanical Engineers to manufacture pressure-retaining equipment in accordance with the ASME Boiler and Pressure Vessel Code (BPVC). This certification requires demonstrated quality management systems, qualified personnel, documented welding procedures, and ongoing compliance verified through authorized inspector oversight. The ASME stamp on a piece of equipment is globally recognized proof that it was designed, fabricated, inspected, and tested to code requirements.
Our capabilities include ASME-stamped pressure vessels, piping assemblies and spool pieces, modular skid packages (process, metering, pumping, chemical injection, compression, gas upgrading), custom packages and assemblies, and components for both traditional hydrocarbon infrastructure and renewable energy systems such as RNG plants and biogas clean-up systems.
We employ GMAW (MIG), GTAW (TIG), Submerged Arc Welding (SAW), Flux Cored Arc Welding (FCAW), and Shielded Metal Arc Welding (SMAW). Process selection depends on the application, material, code requirements, and joint configuration. All welding is performed using qualified procedures per ASME Section IX, executed by performance-qualified welders, and verified by our in-house CWI team.
Quality control is integrated into every production phase. Our system includes incoming material verification and traceability, qualified welding procedures and welder performance testing, in-process inspection at defined hold points by our CWI staff, hydrostatic testing and non-destructive examination (RT, UT, MT, PT), dimensional verification, and comprehensive final documentation packages. We maintain full-time CWI and NACE-certified inspectors on staff to provide continuous oversight—not periodic spot checks.
Yes. While ASME certification is foundational to our quality systems, we also fabricate to API standards, client-specific specifications, and project-particular requirements. Our quality team reviews all applicable specifications before production begins and incorporates them into inspection and test plans.
several common project risks are reduced or eliminated: engineering designs account for actual shop capabilities and tolerances, fabrication schedules are coordinated directly with construction sequencing, documentation and material traceability flow seamlessly between project phases, and change management happens through one integrated team rather than across organizational boundaries. This integration typically results in fewer field fit-up issues, more complete turnover documentation, and better schedule adherence.
We serve clients across oil exploration and production, natural gas extraction, petrochemical processing, refining, pipeline transport, LNG, oilfield services, electric power generation, renewable energy, nuclear energy, bioenergy, energy storage, and alternative fuels.
