Product Description

 Hydraulic Pillar Tube is a kind of material used to make hydraulic supports and cylinders and pillars in coal mine, as well as other hydraulic cylinders and pillars, which are mainly used in hydraulic equipment in coal mining, such as hydraulic pillars, cylinders and plungers.
Hydraulic strut pipe is based on high-quality carbon structural steel, appropriately adding one or several alloying elements, used to improve the steel's strength, toughness and hardenability properties. This type of steel after making, usually need to go through the tempering, chemical heat treatment, surface quenching and other heat treatment. Compared with high-quality carbon structural steel, has good overall mechanical properties, more rolled into a round, square, flat shape of the steel, used as machinery or machines in the important structural parts.

Uses:
Hydraulic Pillar Pipe is mainly used for the cylinder and column of coal mine hydraulic support and pillar.
For hydraulic system, plastic machinery, injection molding machinery, rubber machinery, forging machinery, die-casting machinery, engineering machinery, automotive industry, shipbuilding industry, metal processing, military, diesel engine, internal combustion engine, construction machinery, agricultural and forestry machinery, automation machinery, petrochemical industry, aerospace, hydraulics and pneumatics, air conditioning, shoe-making machinery.
