NPST(none-pressure seal thread) Pup joints Flow line Pipewith weco hammer wing unionare often used in the oilfield as high pressure well servicing lines, fracturing lines, well testing lines, well cementing and circulating lines,discharge lines, auxiliary flow lines, choke-and-kill lines and other well service and stimulation applications.

We CCSCNPST(none-pressure seal thread)are designed and manufactured in accordance with API SPEC.6A and API SPEC.16C standard and they are improved from SPM integral flow line pipe &FMC WECO series integralpup joints.

NPST pup joints flow line pipesare easy for operation and low torque and simple to maintain. Available in lengths up to 20 feet, standard service at cold working pressures up to 20,000 psi and sour gas services at working pressures up to 15,000 psi.

Windlass manufactures Pup Joints with integral hammer lug union end connections. This enables faster, easier make-up and break-out of temporary flow lines.

ADFO manufactures Pup Joints with Integral Hammer Union end connections.These Pup Joints are used on high pressure discharge lines, choke and kill lines, auxiliary flow and other applications.

Prithviraj Industries manufactures Pup Joints up to 20, 000 psi cold working pressure in sizes: 1, 11 /2, 2, 3, and 4-inch bore sizes, lengths to 20 feet.

Pup joints (flowline pipes) are pipe lines with thread, flange or union connectors on both ends, designed to be compatible with FMC Chiksan pup joints and SPM pup joints.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.

Pup joints are forged from superior alloy steel with partial heat treating process, which are widely used for transporting high pressure flow in fracturing line, cementing line and NACE Service. Pup joints have been optimized for minimum weight and size to extend service life, easy to transport and install on site.

- Integral pup joints can be made available with two models, one is plain integral pup joints, another is pup joints with retaining shoulder, integral pup joints with retention shoulder features specially machined shoulder to prevent nut from sliding down pup joints when held vertically.
