Weld-On Pipe Flanges

The available material options include Carbon Steel, Stainless Steel, Alloy Steel, Duplex, and Nickel Alloys. Material selection should account for the piping service, operating conditions, corrosion considerations, and engineering requirements. Customers can request guidance on the available material types when comparing flange options for industrial piping, pipeline, petrochemical, testing, construction, or maintenance work.

The listed size range is ½″ through 72″. Actual availability can vary by flange type, material, pressure class, and sourcing requirements. Providing the required nominal size, configuration, material, and applicable standard helps Twinco Industrial identify suitable options for pipeline systems, industrial piping, hydrostatic testing, construction, fabrication, and maintenance applications.

Product information identifies ASME B16 Series and API Standards, including ASME B16.5 and ASME B16.47 Series A & B. Customers should confirm the applicable standard for their piping design and procurement specification. The required flange type, pressure class, size, material, and project documentation should be reviewed together before ordering.

The listed ASME pressure classes are 150, 300, 400, 600, 900, 1500, and 2500. API ratings are listed from 2,000–15,000 PSI. The correct selection depends on the applicable design standard, piping service, operating conditions, and engineering specification. Customers should verify requirements before choosing a flange class or API-rated option.

Yes. The product information identifies both rental and purchase options. Rental may suit hydrostatic testing, maintenance, shutdown, construction, and other project-specific requirements, while purchase may support recurring inventory or permanent piping installations. Availability and commercial terms are not specified, so customers should request a quote with the required configuration and project details.

Include the required flange type, nominal size, material, pressure class or API rating, applicable ASME or API standard, quantity, and intended application. It is also helpful to identify whether rental or purchase is preferred. These details allow Twinco Industrial to compare suitable options for pipeline applications, industrial piping systems, testing, petrochemical work, construction, welding, or maintenance.
