Our Technology & Capabilities

A seamless fusion of advanced technology and expert oversight ensures your pipe fabrication project is delivered with unparalleled precision and efficiency.

Robotic Pipe Welding

Capability Details & Key Equipment: Our facility includes 5 robotic welding cells with laser vision systems and dual-axis positioners, capable of handling large and complex pipe weldments.

Strategic Advantage for Your Project: Delivers exceptional consistency and precision for high-volume projects, reducing lead times and ensuring every weld is identical.

Precision Spool Fabrication

Capability Details & Key Equipment: We leverage advanced cutting technology, including our Trumpf Tube Laser 7000 (up to 10″ OD) and 5-Axis Lasers, to create spool sections with exacting tolerances.

Strategic Advantage for Your Project: High-accuracy spools ensure perfect alignment for field assembly, minimizing costly on-site welding, rework, and installation delays.

Code & Manual Welding

Capability Details & Key Equipment: We maintain 30+ TIG stations and 40+ MIG stations staffed by welders certified to AWS and ASME Section IX standards.

Strategic Advantage for Your Project: Provides the deep craft expertise required for complex geometries, challenging materials, and the critical root passes on high-pressure piping.

Comprehensive Documentation

Capability Details & Key Equipment: Every project is delivered with a full turnover package, including Material Test Reports (MTRs), weld maps, welder qualifications, and NDT reports.

Strategic Advantage for Your Project: Provides a complete, auditable record of quality and compliance, satisfying the most stringent regulatory requirements and de-risking your project.

Partner with a Certified Pipe Fabricator

For high-pressure, high-temperature, and corrosive environments in the Power, Energy, Chemical, and Oil & Gas industries, structural integrity is the primary mandate. We specialize in fabricating industrial piping that adheres to the strictest engineering codes, ensuring operational safety and reliability.

ASME Code Compliance

Our welding procedures and personnel are qualified in accordance with ASME BPVC Section IX. We have deep experience fabricating systems compliant with ASME B31.1 for Power Piping and ASME B31.3 for Process Piping.

Advanced Welding Processes

With over 60 certified welders and 70+ dedicated TIG and MIG stations, we master the techniques required for volumetric integrity, including Gas Tungsten Arc Welding (GTAW) and Gas Metal Arc Welding (GMAW).

Specialty Alloy Expertise

We are experts in welding materials essential for harsh environments, including Duplex Stainless Steels (2205, 2507) and High-Nickel Alloys like Hastelloy®, which are critical for resisting process-specific corrosion.

Rigorous NDT & Verification

Quality is verified through our on-staff Certified Welding Inspector (CWI) and ASNT SNT-TC-1A Level III personnel. We provide a full suite of Non-Destructive Testing (NDT) services, including Dye Penetrant (PT) and hydrostatic pressure testing, to validate weld integrity.

Sanitary & Hygienic Pipe Fabrication

In the Food & Beverage, Water & Wastewater, and Pulp & Paper industries, the primary driver is preventing contamination and ensuring cleanability. Our sanitary fabrication processes are meticulously controlled to produce smooth, crevice-free systems that meet the highest standards of hygiene.

Hygienic Design Principles

We fabricate piping with a focus on smooth, polished internal surfaces and full-penetration welds that eliminate areas for microbial growth. Our process ensures systems are fully drainable and optimized for Clean-in-Place (CIP) protocols.

High-Purity Welding

We utilize precision GTAW and advanced Laser Welding techniques to produce sanitary welds with minimal heat input and distortion. We understand the critical importance of inert gas purging to prevent internal oxidation (heat tint) that can compromise corrosion resistance.

Material Control & Segregation

Our 160,000+ sq. ft. facility includes stainless-dedicated space to prevent cross-contamination from carbon steel. We use Positive Material Identification (PMI) to verify all incoming alloys, ensuring your project is built with the correct grade of material, such as 304L and 316L stainless steel.

Compliant Finishing

We offer in-house finishing services, including pickling and passivation to ASTM A380 standards, to restore the full corrosion-resistant properties of stainless steel after fabrication.
