Seamless steel pipe >>

Seamless steel pipe >>
Seamless steel pipe is alos called CDS pipes (Cold drawn seamless pipe).

Ceramic Lined Composite Pipes

SHS (Self-propagating High-temperature Synthetic process) ceramic lined steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline. Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa. 

Flanges General

Flanges General
A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system.

Pipe fitting

Pipe fitting
Pipe fitting is work that involves the installation or repair of pipes or tubes. Pipes and tubes are necessary for a wide range of reasons.
