Stainless Steel Buttweld Collar

What is Stainless Steel Buttweld Collar?

A Stainless Steel Buttweld Collar is a type of fitting used to join two pipes or tubes of the same diameter. It is designed to be welded to the pipe or tube, and then joined to another pipe or tube using a similar collar. The collar is made from a high-quality stainless steel material that is designed to withstand high pressures and temperatures. It is commonly used in industries such as oil and gas, chemical processing, and petrochemicals. The collar is manufactured with a precision machining process, ensuring that it fits tightly and securely onto the pipe or tube. It is also available in different sizes and thicknesses, depending on the specific application requirements.

Dimensional Tolerances of Collars ASME B16.9

Dimensional tolerances are in millimeters unless otherwise indicated and are equal ± except as noted.

MSS SP-43 only covers Stainless Steel Buttweld Ffittings 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 B16.9 specifications from NPS 1/2 – NPS 24. Except with regard to the outside diameter at the bevel.
