B&W Pipe, Inc. supplies precision-welded pipe fittings, including butt-weld pipe fittings and carbon steel welded fittings, for oil and gas, water infrastructure, and heavy industrial projects across Texas. Over 20 years of specialist expertise. Deep inventory. Full material traceability on every order.
Your Specialist Source for Welded Pipe Fittings
In industrial piping systems, the quality of your welded pipe fittings determines the integrity of your entire pipeline. Every elbow, tee, reducer, and cap in a high-pressure or high-temperature system must be dimensionally accurate, material-certified, and suited to the specific service conditions of your application. Getting this wrong creates risk to your project schedule, your system performance, and your people.
B&W Pipe, Inc. has been supplying welded pipe fittings to pipeline contractors, project engineers, and industrial operators across Texas since 2001. We are a specialist pipe and fittings distributor with deep expertise in stainless steel welded pipe fittings, butt weld pipe fittings, and the broader range of connection products required for industrial pipeline systems.
Our inventory covers the full spectrum of welded pipe fittings across standard and heavy-wall schedules, with direct mill sourcing from leading global producers and full documentation on every shipment. Whether your project calls for standard ASTM A234 buttweld elbows or large-diameter custom welded fittings to match rolled and welded pipe, we have the stock, the sourcing capability, and the technical knowledge to deliver.
What We Supply:
- Butt weld pipe fittings: elbows, tees, reducers, caps, and stub ends
- Carbon steel welded fittings to ASTM A234 WPB and MSS SP-75 WPHY
- Large-diameter welded fittings to match DSAW and rolled & welded pipe
- High-yield welded fittings for API 5L grade pipeline systems
- Heavy-wall welded fittings for high-pressure industrial service
- Full mill certifications and material traceability on every order
- Hard-to-find sizes, schedules, and grade combinations
Our Welded Pipe Fittings Range
Butt Weld Elbows
The most widely specified welded pipe fitting in industrial pipeline design, our butt weld elbows are available in 45° and 90° configurations, long and short radius, across a broad range of pipe sizes and schedule designations. Manufactured to ASTM A234 WPB and MSS SP-75 WPHY standards, they are engineered for high-pressure and high-temperature service in gas gathering, transmission, and water distribution systems. Long radius elbows are the standard for most pipeline applications, minimizing pressure drop and erosion, while short radius configurations serve where space constraints require tighter routing.
Butt Weld Tees
Equal and reducing butt weld tees in standard and heavy-wall configurations for branching flow in industrial piping systems. Dimensionally compliant with ASME B16.9, our tees are available in a full range of sizes and schedule ratings, from standard carbon steel welded fittings for utility applications through to high-yield grades for high-pressure transmission service.
Butt Weld Reducers
Concentric and eccentric butt weld pipe fittings for diameter transitions within industrial piping systems. Concentric reducers are used where the pipe centreline must remain consistent, while eccentric reducers are specified where the bottom-of-pipe elevation must be maintained critical in pump suction lines and slurry applications. Available in carbon steel welded fittings grades to ASTM A234 WPB and MSS SP-75.
Butt Weld Caps
Carbon steel welded pipe caps for terminating the ends of pipeline runs. Available in standard and extra-heavy wall thicknesses across a broad OD range, conforming to ASME B16.9 dimensional standards. Supplied with full mill certifications and heat records.
Stub Ends
Lap joint stub ends for use with lap joint flanges in systems requiring regular dismantling for maintenance or inspection. Available in short and long pattern configurations to ASME B16.9, in carbon steel welded fittings grades.
Large-Diameter Welded Fittings
For pipeline systems using DSAW or rolled and welded pipe, we supply and source large-diameter butt weld pipe fittings engineered to match your pipe OD, wall thickness, and grade. These fittings, often fabricated to project-specific drawings, are used in large-bore water transmission mains, outfall pipelines, offshore structural systems, and heavy industrial applications where mill-standard fittings sizes are insufficient.
Carbon Steel Welded Fittings, Our Core Specialty
Carbon steel welded fittings represent the backbone of B&W Pipe’s fittings supply capability. Our entire distribution network, mill sourcing relationships, and technical expertise are built around carbon steel, which means when you order carbon steel welded fittings from us, you’re working with specialists, not a generalist supplier trying to cover every material category.
Our carbon steel welded fittings inventory covers the primary grades and standards specified across oil and gas, water infrastructure, and industrial facility projects:
Specification | Description | Typical Application |
ASTM A234 WPB | Standard carbon steel buttweld fittings | Gas & water pipeline systems |
ASTM A234 WPC | Higher strength carbon steel buttweld fittings | Higher pressure service |
MSS SP-75 WPHY 42–70 | High-yield wrought buttwelding fittings | API 5L grade pipeline systems |
ASTM A420 WPL6 | Low-temperature carbon steel fittings | Cold climate pipeline applications |
ASME B16.9 | Dimensional standard for factory-made buttweld fittings | All buttweld applications |
Every carbon steel welded fitting we supply ships with mill test reports, heat certifications, and dimensional records, providing the material traceability your quality management system requires.

Industrial Applications
Our welded pipe fittings serve critical roles across a wide range of industrial pipeline environments:
Natural Gas Gathering & Transmission
Butt-weld pipe fittings and high-yield carbon steel welded fittings for upstream gathering lines, midstream transmission headers, compressor station piping, and metering skids. MSS SP-75 WPHY grades match the high-yield API 5L pipe grades used throughout these systems.
Large-Diameter Water Transmission
Butt weld elbows, tees, and reducers for municipal water mains, penstocks, intake and outfall pipelines, and water treatment facility interconnects. Often specified alongside rolled and welded pipe, where large ODs exceed standard mill production ranges.
Petrochemical & Refinery Process Piping
Carbon steel welded fittings for process headers, utility systems, and interconnect piping within refineries and chemical processing plants. Heavy-wall schedule fittings for elevated temperature and pressure service.
Offshore & Subsea Structures
Large-diameter welded pipe fittings for offshore platform process piping, structural connections, and subsea pipeline systems where certified, traceable materials are a non-negotiable requirement.
Power Generation
Butt weld pipe fittings for steam generation, cooling water, and fuel gas systems within power plants and cogeneration facilities, including high-schedule carbon steel welded fittings for elevated service conditions.
Civil Infrastructure
Large-diameter butt weld fittings for tunnel liners, outfall pipelines, penstock systems, and foundation pile connections where custom-fabricated welded pipe fittings are required to meet project-specific dimensional requirements.
Why B&W Pipe for Welded Pipe Fittings
Built Around Carbon Steel Welded Fittings
B&W Pipe was established specifically to serve the pipeline and industrial pipe market. Carbon steel welded fittings are at the core of what we distribute. You’re working with specialists who understand grades, schedules, end prep standards, and weld compatibility, not a generalist catalog supplier.
Deep Inventory Including Hard-to-Find Sizes
Standard sizes ship from stock. Niche ODs, heavy-wall schedules, and uncommon grade combinations are sourced through our mill relationships. If a standard distributor can’t supply it, that is exactly the kind of requirement B&W Pipe was set up to handle.
Large-Diameter Welded Fittings Capability
Our rolled and welded pipe fabrication capability means we understand and can source large-diameter butt weld pipe fittings that go beyond standard mill catalog ranges, a capability that very few distributors in Texas can match.
