Product Description

Cold Drawn Precision Seamless pipe
Precision Seamless Pipe 
42CrMo 34CrMo4 PG115 PG135 PG145 alloy pipe for perforating gun carrier

Precision seamless pipe is a pipe material producing by a cold drawn process with high precision and high-quality finish.
CDS is popular in the hydraulics, being used to make hollowed chrome plated telescopic cylinders and hydraulic rods. It is also popular for large bore, heavy walled, high pressure hydraulic cylinders.
Cold Drawn Seamless tubes also find uses in heavy equipment manufacturing such as cranes and garbage trucks.
Due to the characteristics of high-precision, in precision machinery manufacturing, auto parts, hydraulic cylinders, construction (steel sleeve) industry has a very wide range of applications.
