Pup Joint
Pup joint is used be
adjust height of tubing or casing strings or depth of down-hole
tools, and these pup joints are made of seamless steel pipes. Pup joint can be available with tubing pup joint or casing
pup joint, and material for pup joint can be availalbe in J55, K55, N80, L80 or P110,
sizes of tubing pup joint range from 2⅜” to 4½”, and casing pup joint
range from 4½” to 13⅜”, thread of pup joint can be 8RD, 10RD
or BTC, length of tubing pup joint are often offered in 2ft, 3ft, 4ft, 6ft, 8ft, 10ft and 12ft, length of pup joint for special purpose can be available as per order.
Pup joints are machined with interchangeable Pin & Box thread on two ends or other configuration, one end is equipped with coupling, and another end is protected with closed end thread protector. Nominal weight of tubing pup joint is the same as tubing, and casing pup joint is the same as casing.
Tubing pup Joint
Tubing pup joints are desiged and manufactured as per API
5CT to be used be adjust height of tubings, and tubing pup
joints are made of seamless steel tubings. Material grade of
tubing pup joint can be avalialbe in J55, K55, N80, L80 or
P110, sizes of tubing pup joint range from 2⅜” to 4½”,
thread of pup joint can be 8RD, 10RD or BTC, and end
connection types can be NUE and EUE. length of tubing pup
joint are often offered in 2ft, 3ft,
4ft, 6ft, 8ft, 10ft and
12ft, length of pup joint for special purpose can be
available as per order. Tubing pup joints are machined with
interchangeable Pin & Box thread on two ends or other
configuration, one end is equipped with coupling, and
another end is protected with closed end thread protector.
Nominal weight of tubing pup joint is the same as tubing.
Tubing pup joints are internally and externally hydrostatic tested
with tension and compression loads, and torque tested,
electromagnetically inspected, pup joint is full-body drift and straightness visual inspected,
and phosphated and dye-penetrant inspected. and finally painted by machine to ensure excellenct appearance. Finished tubing pup joints are often packed by steel belts in bundles, and then fixed in steel rack for easy transportation.

Casing pup joint
Casing pup joints are desiged and manufactured as per API 5CT to be used be
adjust height of casings, and casing pup joints are made of seamless steel casings. Material grade of casing
pup joint can be avalialbe in J55, K55, N80, L80 or P110,
sizes of casing pup joint range from 4½” to 13⅜”, thread of pup joint can be 8RD, 10RD
or BTC, length of tubing pup joint are often offered in 2ft, 3ft, 4ft, 6ft, 8ft, 10ft and 12ft, length of pup joint for special purpose can be available as per order. Casing pup joints are machined with interchangeable Pin & Box thread on two ends or other configuration, one end is equipped with coupling, and another end is protected with closed end thread protector. Nominal weight of casing pup joint is the same as casing.
Casing pup joints are
