Study on Microstructures and Properties of Composite Pipe Made by Centrifugal SHS;

A composition gradient of alloying elements exists in the iron-nickel alloy layer in the radial directio n of the composite pipe.

The microstructure of the iron-nickel alloy lined layer in a composite pipe produced by centrifugal-thermit process was investigated The radial composition distribution of the alloying elements in the lined layer was analyzed The results show that the iron-nickel alloy was composes of austenite and ferrite A martensitic transition region ca.

Research Progress of Inner Ceramic-lined Compound Steel Pipe by SHS;

Liner stainless steel compound steel pipe is the stainless steel pipe compound thin wall thickness on the inside wall of steel pipe and it also has properties and advantages and increases pipe wall thickness.

Welding and weld crack restoring of 304+20R composite steel tube;

It is required that the pipe material for transporting slurry and powder medium shall have wear resistance,a long life span and high strength with easy construction and erection and a moderate price,and the wear resistant porcelain lined complex steel pipe can meet the above mentioned requirements.
