Ductile Iron Pipe Fittings Can be Tapped Directly

May 15, 2018

Ductile Iron Pipe Fittings could be direct exploited for air discharge valves, sampling portsand support connections, etc.. Testing has proven that, with the usage of a great thread sealant, as few as one complete thread engagement will offer a leak-free tap. Observing the traditional nature of the business, we advise that you select at least 2 full threads of participation.

The limiting factor in attaining sufficient thread engagement for any particular metal thickness is that the relative curvature of the parent body because the dimensions of the tap raises. You will find tables in AWWA Fittings that show the maximum dimensions of tap which may be employed on a particular size of pipe, and depth to reach 3, 2, or 4 thread involvement.

Additionally, you can purchase DI Flanged Pipe Fittings using a boss throw in the location of their desired tap. The horizontal surface of the supervisor, together with the greater metal depth, supplies for multiple thread involvement of tap dimensions bigger than can be accommodated to the curved surface of the matching.
