MSS SP-43 Wrought and Fabricated Butt-Welding Fittings
Valour Alloys Inc., we carry a full inventory and Supply MSS SP-43 Buttweld Fittings products in a variety of sizes widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.
MSS SP-43 only covers stainless steel buttweld fittings made for use with Schedule 5S and 10S pipe and Stub Ends suitable for use with Schedule 40S pipe, as defined in ASME B36. 19. The dimensions and dimensional tolerances defined in MSS SP-43 are substantially the same as those in ASME B16.
MSS SP-43 Buttweld Fittings, also known as the Standard Practice for Light Wall Stainless Steel Butt-Weld Fittings for Aqueous Corrosive Applications, is a specification developed by the Manufacturers Standardization Society of the Valve and Fittings Industry (MSS). These fittings are designed for use in various industrial applications, particularly in situations where corrosion resistance is essential. MSS SP-43 is especially relevant for light wall stainless steel butt-weld fittings used in aqueous corrosive environments.

Material: MSS SP-43 Buttweld Fittings are typically made from stainless steel and designed to provide excellent corrosion resistance. The specific stainless steel alloy used can vary depending on the application's requirements.
Welded Construction: These fittings are designed for butt-welding, providing a strong and leak-resistant connection between pipes and components. Butt-welding involves the fusion of the ends of pipes or components together.
Size Range: MSS SP-43 Buttweld Fittings are available in a range of sizes to accommodate various pipe diameters and system requirements.
Types: These fittings come in various types, including elbows, tees, reducers, and caps, among others. The specific type and size needed depend on the configuration and requirements of the piping system.
Standards: MSS SP-43 provides the standard specifications for these buttweld fittings, ensuring that they meet certain quality and performance standards for their intended use.
Quality and Testing: The fittings are typically manufactured to meet high-quality standards and undergo various tests to ensure they meet the required specifications, including pressure testing and material analysis.
MSS SP-43 Buttweld Fittings play a crucial role in ensuring the integrity and longevity of piping systems in corrosive environments. Their adherence to specific standards and their robust construction make them a reliable choice for industries where corrosion resistance is a priority.
