2 fig 1502 pup joint factory

we offers robust integral pipe in sizes 2” through 3” in pressure ratings to 15,000 psi CWP. Integral pipe is recommended for use in applications where strong cyclic loading is possible. Our integral pipe is available in

EASTSUN has pup joint mill in both China and Vietnam. We supply to the countries has no anti-dumpling to china pup joint from China mill, and supply to the countries has anti-dumpling to china pup joints like USA, CANADA from Vietnam mill.

The design of the NPST pup joint takes end connections and attaches them to threaded pipe. The quality of these parts is critical to form and function. Our process is designed for a seamless integration between pipe and union. It’s hard to tell where one part begins and the other ends.

High pressure Pup joint is a kind of pressure pipe with hammer union end or flange end connection,the high pressure pup joint can be made integral or weld type which end connection is welded to pipe. Cost of Intergal type is higher than welded type.

Hammer union end connection pup joint is designed to interchangable with weco wing union, including Fig100, Fig206, Fig207, Fig602, Fig1002, Fig1502, Fig2002, Fig2202 and etc.

Flange end connection pup joint is designed according to API 6A or ASME standard. Working pressure of pup joint is from 2,000 psi to 20,000psi.Manufacturing theory is according to API 16C. Our company supply high pressure weco pup joints with four types:

Pup joints size : 1″~4″, Working pressure: 7MPa~150MPa, Length of the pup joint: 1m. , 1.5m, 2m, 2.5m, 2.8m. High-pressure straight pipes of various sizes and pressures as well as acidic environments are available upon request. Application: Fracturing manifold, cementing manifold, maintenance manifold, test manifold, high-pressure well service flowlines, fracturing flowlines, well testing flowlines, cementing and circulating flowlines etc.

The Union Straight pipes and elbow are designed as per API Spe 16C and made by low carbon alloy steel with integral forged, H2s as per NACE MR0175 Standard. The straight pipe with WECO Union connection is applied for connection of well surface testing equipment. The straight pipe one end is union female in Fig 602 or FIG1502, another end is union male in FIG602 or FIG1502, the nominal size is 3”, length can be 0.5m to 5m. We are able to supply straight pipe in various size with union connection.

PME integral pup joints are forged from material AISI 4130 in high grade alloy steel. It also called one piece pipe straight as terminal connection unions are forged integrally with pipe body, but not welded pup joints.

Proceeded with forging, drilling, heat treatment by quenching and tempering, sand blasting and machining, pup joints PME forge for our clients by premium alloy steel material code 4130. Chemical composition, mechanical property and ultrasonic testing result is issued on PME certificates report for each manufacturing procedure.

Integral → The pup joints are one-piece construction made from alloy steel and feature wing union end connections that eliminate welds and threads. The pup joints are capable of handling a variety of fluids and a working pressure of 15,000 psi. Available in lengths up to 15 feet, they are pressure rated to 10,000 psi for sour gas service.

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.

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.

⑷.Each technical parameters and performances of pup joints conform to standards of API Spec 6A and can be exchanged with like products internationally.
