Product Description

Standard GB/T14975, GB/T14976, GB13296-91, GB9948 ,ASTM A312, ASTM A213, ASTM A106,ASTMA53 ASTM A269, ASTM A511,JIS349, 



A seamless tube, also known as seamless pipe, is a tube that has no seam or a weld-joint. It is a solid metal tube with a uniform structure. Each end is connected to another tube without any welding joints. This increases the ability to withstand high pressure, corrosive atmosphere, mechanical stress, and very high temperature. Seamless tubes have a thread-like structure at one end or both at times. This is used to connect the end of another hollow tube.

Seamless tubes are considered to be strong enough to resist high pressure from numerous industrial forces. This is not possible in a welded tube, because, a seam or joint acts as a weak section for the tube. A hydraulic seamless tube is specifically designed to resist dynamic loads and high static offering an enduring, staunch solution.

Hydraulic seamless tubes are widely used in petrochemical industries, refineries, power industries, chemical industries, aerospace industries, automotive industries, etc. Heat exchanger tubes, hydraulic tubes, boiler tubes, mechanical tubes, finned tubes, etc. required in these industries are hydraulic seamless tubes.

For example, the heat exchanger tubes are used to transfer heat from one medium to another for heating and cooling processes. These tubes are considered to be more reliable and strong as they do not have any joints. Mostly, the overall energy efficiency of a plant can be determined by these tubes.

The length of seamless tubes is comparatively short whereas welded tubes are available in long continuous lengths because of the joints.
