About This Resource

Carbon Flanges is a comprehensive technical resource designed for engineers, procurement teams, and project managers. We provide detailed guides, standards documentation, and best practices for flange selection and specification across all applications and pressure classes. Backed by a supply partner serving the flange industry since 1986.

About This Resource

Carbon Flanges is a technical resource for engineers, procurement teams, and project managers who need reliable information about carbon steel pipe flanges, lightweight large-diameter flanges, and industrial piping components. This site provides comprehensive guides, standards documentation, and industry best practices to support flange selection and engineering decisions across all industrial applications.

This resource covers carbon steel flanges (ASTM A105, A350 LF2, A516, A694), lightweight and large-diameter solutions (Class 125LW, AWWA C207), weld neck, slip-on, threaded, socket weld, and lap joint configurations, and practical engineering guidance for specification, selection, installation, and maintenance. Standards coverage includes ASME B16.5, ASME B16.47, AWWA C207, AWWA C228, ANSI, DIN, and API specifications.

When you're ready to source flanges that meet your specifications, contact our supply team for quotes and delivery support. Our partner supplier can provide standards-compliant flanges from inventory, custom engineered solutions, complete material documentation, and rapid turnaround on specialized requirements. For quotes and sourcing, contact our supply team at (281) 484-8325 or sales@texasflange.com.

Mission & Core Values

Direct Source

Flanges are sourced direct from qualified mills and stocking distributors. Direct relationships mean faster communication, transparent pricing, and accountable lead times.

Standard Compliance

Every flange engineered to ASME, ANSI, AWWA, API, or DIN standards with full Material Test Reports and pressure-temperature certifications. No shortcuts on compliance.

Availability

Stocked sizes can ship quickly; custom work runs on industry-leading turnaround. Call (281) 484-8325 for project-specific timelines.

Engineering Resources

Technical references that engineers can rely on to verify specifications and cross-check standards before a quote goes out.

Complete Traceability

Heat number documentation, material certifications, dimensional reports, and pressure ratings all bundled. Audit-trail ready from day one.

Engineer-Oriented

The supply partner behind this resource works engineer-to-engineer on specifications, not from a pure order-desk script.

Our Quality Commitment

Standards-Aligned Documentation

Flanges are sourced and supplied against applicable standards (ASME, ANSI, AWWA, API, DIN). Full documentation can be provided with every shipment.

Complete Material Traceability

Material Test Reports with heat number documentation, chemical composition analysis, mechanical properties, and material certifications. Trace every flange to its source material.

Dimensional Accuracy

Every flange inspected for OD, bore, bolt circle, bolt hole diameter, and face thickness. Third-party measurement reports available for critical applications.

Pressure-Temperature Certification

All flanges rated and certified against ASME B16.5 pressure-temperature tables. You get engineering certification that your flange is safe for your operating conditions.
