Approved Import Slip On Flanges

Slip-On Flanges for Industrial Pipe Connections - Approved Import Range

Slip-on flanges are widely used in industrial piping systems where a reliable, welded connection is needed for process lines, equipment hookups and general plant installations. This collection features approved import slip-on flanges sourced for industrial use, suitable for piping projects that require consistent dimensions, stable welding surfaces and compatibility with common pipe schedules used across the U.S. market.

These flanges are designed to slide over the pipe and are then fillet-welded on the inside and outside, giving the joint strong support for operational pressure. Because they sit flush with the pipe, slip-on flanges are a common choice in fabrication shops, maintenance teams, water treatment setups, gas processing lines and general mechanical piping work.

Design and Functional Details

Approved import slip-on flanges provide a clean welding surface and a flat hub, allowing a straightforward fit-up during fabrication. They are available in standard ASME dimensions so installers can match them with existing flanged systems used in industrial plants. Many facilities choose slip-on designs when ease of alignment is important or when the job involves repetitive pipe connections that must maintain structural integrity over long operating cycles.

Material selection plays a role in durability. Carbon steel slip-on flanges are often used for high-temperature and high-pressure service, while stainless steel options may be selected for lines carrying corrosive fluids or systems exposed to moisture. Installers working with raised-face assemblies can also refer to our raised face options for compatible gasket seating and connection styles.

Industrial Applications and Use Cases

Slip-on flanges are commonly used in applications such as:

• process piping networks
• mechanical pipeline construction
• pump and valve connections
• compressed air systems
• water and utility pipelines
• fabrication projects in industrial shops
  

Their installation process is straightforward for welding teams, making them a practical choice for new construction, plant modifications or routine line replacement work. In systems requiring different flange configurations, our industrial weld neck flanges and blind flange closures can be used alongside slip-on connections within the same project.

Approved Import Slip-On Flanges from Trupply

This collection provides industrial buyers with access to slip-on flange options suitable for a wide range of plant and facility piping needs. Customers can select sizes, pressure classes and material types based on the requirements of their project. Each item aligns with standard industry dimensions, helping installers match these flanges with pipe fittings already in service.
