Product Description

As a professional high quality Oil Drilling Short Circuit manufacturer, you can rest assured to buy Oil Drilling Short Circuit from YITAI and we will offer you the best after-sale service and timely delivery.

Oil Drilling Short Circuit 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 Integral type is higher than welded type.

There are two type ends for the high-pressure straight pup joint / pup pipe (straight pipe assembly): hammer union end, flange end.

Union type pup joint / straight pipe assembly

Working pressure: 7MPa ~ 140MPa.

Nominal diameter: 1″~5″

Pipeline length: 0.5m ~ 6m

Temperature grade: -29ºC~121ºC (PU grade)

Connection form: Hammer union end connection pup joint is designed to interchangeable with weco wing union, including Fig200, Fig206, Fig207, Fig602, Fig1002, Fig1003, Fig1502, Fig2002, Fig2202, etc.

Flange type pup joint / straight pipe assembly

Working pressure: 7MPa ~ 140MPa.

Nominal diameter: 1″~5″

Pipeline length: 0.5m ~ 6m

Temperature grade: -29ºC~121ºC (PU grade)

Connection form: Flange end connection pup joint is designed according to API 6A or ASME standard, 2 1/16" flange, 2 9/16" flange, 3 1/8" flange, 3 1/16″ flange, 4 1/16″ flange, etc.

Working pressure of pup joint is from 2,000 psi to 20,000psi. Manufacturing theory is according to API 16C. Our company can supply four types high pressure weco pup joints: pressure threaded seal, non-pressure threaded seal, integral type, and welded type.

It is widely used in oil drilling, cementing and fracturing, testing operations, etc.

According to user needs, we can provide high-pressure straight pipes / pup joint of various models and pressure grades used in environment such as ordinary standard, low temperature and H2S service containing hydrogen sulfide.

Pup Joints are manufactured from seamless alloy steel tubing, hot upset forged to provide superior grain structure, and precisely machined to the same high quality standards as our hammer unions. Pup Joints are designed for long service life, with optimum wall thickness to carefully balance erosion resistance and weight. Every Pup Joint is permanently serial numbered for traceability and service records maintenance.
