1 1/2 Stainless Steel Pipe Unions

Yes. The product information identifies stainless steel as an available material for Twinco Industrial’s small bore fittings. Carbon steel and specialty alloys are also listed among the material options. Confirm the required material grade and project specification with Twinco Industrial before purchase to ensure the selected union is appropriate for the process conditions and installation requirements.

Twinco Industrial’s small bore fittings are available in threaded and socket-weld configurations. The appropriate connection depends on the piping design, installation method, operating requirements, and project specifications. When requesting a 1 1/2 Stainless Steel Pipe Union, provide the required connection type and any applicable documentation or standards so the product can be matched accurately.

The listed small bore fittings are identified as compliant with ASME B16.11 and MSS-SP-83. The product information also references ASME B16 Series and MSS-SP Standards as certification or specification categories. Buyers should verify the exact standard applicable to the requested union, along with material and configuration details, before approving it for a particular piping system.

The product information lists pressure classes from 3000# to 6000# for the small bore fittings range, which includes unions. The correct pressure class depends on the system design, operating conditions, and applicable engineering specification. Confirm the required class when requesting a 1 1/2 Stainless Steel Pipe Union so the quotation reflects the intended application.

Yes. Instrumentation systems are explicitly listed as an application for the small bore fittings range. A 1 1/2 Stainless Steel Pipe Union may be considered where its material, connection type, pressure class, and dimensional requirements match the system design. Twinco Industrial can help review the requested configuration and provide information for the intended instrumentation application.

The listed small bore fittings range includes elbows, tees, couplings, unions, reducers, caps, bushings, olets, and branch fittings. Availability and configuration may vary by material, connection type, and pressure class. If a union is not the required component, provide the piping layout or fitting specification so Twinco Industrial can help identify a suitable option.
