Pup joint is cementing and fracturing equipment delivery High Pressure Fluid Control Products. Widely used in the acidic operating environment (excluding containing CO2, H2S sour gas operating environment) in the high-pressure discharge line, input line, a temporary flow line, well testing, and other high-voltage transmission lines on pipelines. Pup joint specifications are 1 in ~ 4 in, length 0.5 m, 1 m, 1.5 m three kinds, rated working pressure 42MPa ~ 105MPa, working temperature -46 ℃ ~ 121 ℃.
⑴.The high pressure pup joint designed and manufactured by our company is forged by high quality structural alloy steel. Terminal union is forged together with pipe, which is able to avoid disassembling and ensure good sealing, small weight, convenient use and fast installation. high pressure Pup joint has various specifications including 1"~4" and lengths including 1', 2', 3', 4', 5', 6'etc, rated working pressure is 42MPa~105MPa. Any specification of pup joint or even integral pup joint special for acid environment is available according to users' needs;
⑵.Except for integral pup joint, our company is also supplying pressure thread sealing pup joint, non-pressure thread sealing pup joint and welding pup joint.
2. Design features
Pup joint technical parameters and performance specifications are in line with API 6A. Its product specification level PLS3, performance levels for the PR2, it can work with SPM's similar products interchangeable.
Pup joint made of high strength steel, with a special toughening process. It uses Acme threaded connection, making it with the demolition convenient, fast, reliable connection, and reliable. Multiple seal design and high precision, to ensure the sealing performance of Pup joint.
⑴.The integral pup joint is union instead of screw connection on the top, which is more secure and reliable;
⑵.Easy and quick assembling and disassembling;
⑶.High strength and low weight;
⑷.Each technical parameters and performances of pup joints conform to standards of API Spec 6A and can be exchanged with like products internationally.
