Stainless Steel Buttweld Swage Nipples

What is Stainless steel buttweld swage nipples ?

Stainless steel buttweld swage nipples are fittings used to connect two different sizes of pipes or to reduce the diameter of a pipe. They have a buttweld connection on one end and a threaded or plain end on the other. They are made of high-quality stainless steel, which makes them resistant to corrosion and suitable for use in harsh environments. They come in different sizes and finishes to suit different piping applications.

Stainless steel buttweld swage nipples are commonly used in industries such as oil and gas, chemical processing, and water treatment. They are ideal for applications that require high pressure and high temperature. Their design allows for easy installation and removal, making them ideal for maintenance and repair work.

Overall, stainless steel buttweld swage nipples are a reliable and durable option for connecting and reducing pipes in various piping applications.

ASME B16.9 Swedge Nipple Dimensional Tolerance

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

MSS SP-43 solely covers stainless steel butt weld fittings created to be used with Schedule 5S and 10S Swedge Nipple appropriate to be used with Schedule 40S pipe, as outlined in ASME B36.19. The scale and dimensional tolerances outlined in MSS SP-43 area unit considerably a similar as those in ASME B16.9 specifications from NPS 1/2 — NPS twenty-four. Except with relation to the skin diameter at the bevel.

Nominal Pipe Size (inch)	Overall Length (mm)	Outside Diameter at End		Wall Thickness (prior to threading or grooving)
		Square Cut Ends (mm)	Other End Connection (mm)
1/8” to 3/8”	± 1.5	+ 0.40 – 0.80	± 0.80	Not less than 87.5% of nominal wall thickness
1/2” to 1-1/2”	± 1.5	+ 0.40 – 0.80	+ 1.50 – 0.80
