Import Threaded Flanges

Buy Import Threaded Flanges for Practical Piping Jobs

Import Threaded Flanges are a common choice on U.S. plant floors where welding is not practical or not preferred. These flanges screw directly onto the pipe, which makes them useful for maintenance work, retrofit lines and smaller diameter piping systems. In many facilities, they show up in utility services, low to moderate pressure lines and areas where shutdown time needs to stay limited.

At Trupply, this collection focuses on import threaded flanges that meet everyday industrial needs without driving up project cost. If you are sourcing flanges for routine piping work, this category keeps things simple and familiar.

Where Threaded Flanges Make Sense in the Field

Threaded flanges are typically used on smaller pipe sizes and thicker wall pipe. Thin wall pipe cannot be threaded safely, so schedules like Schedule 80 are commonly specified. ASME B31.3 guidance also limits their use in higher pressure or higher temperature services, especially for steam and hot water applications.

In real-world operations, these flanges are often selected for water lines, compressed air, fuel oil and similar services where crews want straightforward installation. Some plants also apply a seal weld over the threads for added security, depending on service conditions and internal standards.

Budget Threaded Flanges Without Overbuying

Many buyers come to this collection looking for budget threaded flanges that still align with standard dimensions and pressure classes. Import options are widely used across U.S. facilities for non critical systems and secondary lines.

Threaded flange price is usually influenced by size, pressure class, material grade and machining quality. Import flanges help procurement teams balance cost targets while keeping specifications aligned with common ASME requirements. For projects that do not require domestic origin, these flanges are often a practical call.

Common Specs Buyers Look For

Most import threaded flanges are stocked in common pressure ratings like Class 150 and Class 300. Sizes are generally focused on smaller diameters where threaded connections are accepted industry wide. Material options typically include carbon steel suitable for general industrial service.

If your system calls for other connection types, you may want to also shop weld neck flanges, slip on flanges, or socket weld flanges within the Trupply catalog for a consistent sourcing process.

Sourcing for Maintenance and New Builds

Maintenance teams often buy import threaded flanges for repairs and tie-ins, while project buyers use them for auxiliary piping on new builds. If your goal is reliable fit up, familiar installation and controlled cost, this collection fits well into standard U.S. industrial purchasing workflows.
