About

About This Resource

A technical reference for engineers, contractors, and procurement teams working with ASME, ANSI, AWWA, and API flanges and pipe fittings.

Scope

ASME Flanges is an informational resource covering industrial pipe flanges, fittings, and related piping components. The site provides technical reference material on flange standards, material specifications, pressure-temperature ratings, and application guidance across oil and gas, petrochemical, water/wastewater, power generation, and general industrial sectors.

Whether you are specifying flanges for a new construction project, sourcing replacements for a turnaround, or researching material options for corrosive or high-temperature service, this resource is designed to help you make faster, more confident decisions.

For sourcing, quotes, and technical support, contact our supply team at (281) 484-8325 or email sales@texasflange.com.

Supply Capabilities

What We Bring to the Table

Beyond reference material, this resource connects you to a supply team that stocks standard and custom flanges for immediate and project-based delivery.

Full Traceability

Every flange is supplied with mill test reports traceable to the original heat number. EN 10204 3.1 and 3.2 certificates are available on request.

Specification Verification

Service conditions are cross-referenced against ASME pressure-temperature tables before quoting. If the spec does not fit the duty, we flag it.

Dimensional Accuracy

Bolt holes, raised faces, bore tolerances - all measured and documented. QC catches problems before they reach the field.

Domestic & Import Sourcing

Buy American and BABA/AIS compliant flanges are stocked. Import options are available for projects where competitive pricing is the priority.

Specialty Materials

Duplex, super duplex, Inconel, Monel, Hastelloy, and chrome-moly alloys are sourced through established supply chains for demanding service conditions.

Custom Configurations

Non-standard bores, overbore flanges, special facings, and tight-tolerance work are sourced from qualified machine shops with full documentation.
