Hot Tapping or pressure tapping is the method of making a connection to existing pipelines or vessels while the existing system is under pressure.

This method employs a drilling or tapping machine and a full bore valve and either a nozzle or a full encirclement fitting welded to the existing pressurised system.

The drilling machine, generally consists of a telescoping boring bar mechanically driven by our specially designed gear box which advances a cutting tool.

A necessary element in the hot tap procedure is the full bore valve (however if the client decides that the line is to be depressurised a valve is not required).

If a valve is required this allows the tapping machine to be removed after the cutting operation, flange ratings are from 150lb through 900lb ANSI ratings.
