Casing and Tubing API
- Applicable standards API Spec 5CT and API Spec STD 5B
- Pipes are used to extract oil or natural gas from a well
- While the casing is used to build the wall of the oil (gas) well.
Steel tubular product Bimetallic
This new type of clad tubular product made
entirely from related metallurgical processes is
suitable for a wide application range covering
sectors dealing with highly corrosive operating
conditions such as petroleum industry,
chemical industry and offshore platform
operation, etc. Metallurgical layer, the tube is
also able to meet the requirements of heavyduty operating conditions for conveying
pulverized coal in power plant, pulverized ore
and tailing pulp in mines and so on
Specialized tubular products
for sections
other than the petroleum industry
Pipes for the chemical industry

sodium carbonate, ethylene, etc.
Pipelines for the petroleum refining industry
Tubing for oil refining furnaces, tubular fittings and piping systems
related to oil refining.
Pipes for boiler making purposes
Tubes for steam boilers and boiler tube systems of normal or
higher pressure
Casing and Tubing with CST Premium Connection
CST premium connection is a new type of gas seal
connector which developed many years with practical
experience by our company.
Taking the theory of interference fit from metal-metal and
according to pressure requirements for tubing and casing
in the environmental conditions, this new type of gas seal
connector is to be designed with different assembling
interferences and sealing area to meet different
requirements for gas seal through making the pressure on
the gas seal surface higher than the outer of pipe or inner
pressure from pumped medium.
CST premium connection features advantages as the same
as other premium connection with all the performance
target values reaches or exceed to these connections.
