Ship-Building

Seamless steel tubes are used in ship hydraulic system and ship diesel engine. In diesel engine high pressure fuel pipe can afford high pressure with high strength.

In hydraulic system seamless steel tube

also can be widely used.

Engineering Machinery

Seamless steel tubes are widely used in the hydraulic system oil pipe of the Industry machinery. It can afford high pressure with high strength.

Automotive

Our seamless steel tube widely use in automotive.
Brake system: hydraulic brake tube
Steering system: high pressure oil pipe, return oil

pipe
Fuel system: oil supply and return pipe

Hydraulic System

SMLS steel tube usually used for fluid oil pipes in hydraulic systems, because the inner and outer walls of precision seamless steel tubes have no oxide layer, high

pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening and no cracks.

Also with long working last than hose.

Heat-Exchangers

Application

Heat exchanger tubes are suitable for petroleum, chemical, boiler and many other industrial fields, heat exchangers, condensers, superheaters or similar heat transfer equipment, according to different use environment, can choose different carbon steel or alloy materials.
