SWAGE NIPPLES and BULL PLUGS

GENERAL INFORMATION

Capitol Manufacturing Company's Carbon Steel Swage Nipple Products are manufactured in accordance with the ASME/ASTM SA234WPB and MSS-SP95 specifications. The raw materials used in manufacturing these products are A106 Grade B Seamless pipe and/or cold drawn, low to medium carbon, barstock. As a rule, 1" and smaller sizes will be made from hex barstock and most 1 1/4" and larger sizes will be made from pipe. Where pipe is not a practical raw material, round barstock will be used. No sacrifice of properties will result from this practice.
