Cold galvanized pipe — more precisely electro-galvanized or pre-galvanized pipe — carries a thin, uniform zinc coating that is applied electrolytically rather than by dipping in a

Hot dip galvanized pipes are formed by reacting molten metal with an iron substrate to form an alloy layer, thereby combining the substrate and coating.

Steel pipe is strong, rigid, and economical, but bare steel corrodes in contact with water, soil, and weather. Galvanizing applies a zinc coating that protects the steel both as a

Each end of the coated steel pipe should be covered to prevent dust from entering the pipe.

A steel pipeline's external coating is its first line of defense against corrosion, and the entire coating investment can be defeated by a single undetected defect. Test methods ex

The coating layer should be smooth and flat, without scratches, cracks, pinholes and adhesion of foreign bodies and other defects.

Seamless steel pipes are classified in four practical ways: by production method, by material, by application and by cross section. This article explains each classification, the g

The production process of general seamless steel pipes can be divided into two types: cold drawing and hot rolling.

Supply is divided into three categories according to different purposes.

Carbon steel pipe remains the backbone of industrial piping because its technical parameters can be tuned across a wide performance window. This guide translates those parameters -

The raw material of the carbon steel pipe is a round tube blank, and the round tube embryo is cut by the cutting machine and the growth of the blank is about 1 meter, and is sent t

Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes.
