High Pressure Flowline
General:
Pup joints (flowline pipes) are pipe lines with thread, flange or union connectors on both ends. Various pup joints are available for high/low pressure and temperature and H2S environment such as integral pup joints (10 feet length to handle fluids at cold working pressure), sour gas pup joints, pressure thread seal straight pipes and non-pressure thread seal pup joints.
The high pressure pup joint is made of high quality alloy steel and the end is connected by the union. Its specifications have 2'',3'' and 4'' and working pressure is 6000PSI-15000PSI.The length depends on the demand of clients.
