In a solar tracking system, the torque tube is a critical structural component, especially for single-axis solar trackers.Torque tubes have been used in solar tracker designs to handle both bending and torsional forces. 

Boiler Tube

hese Boiler pipes are classified into two different types:medium pressure pipes and  / high pressure pipes. Boiler tubes are welded , which makes them resistant to many different types of wear and tear. 

Pipe Machining

Pipe machining is the forming operation, and it encompasses the various procedures used to cut, size, and shape raw pipe material into the appropriate shape.

Pipe Coating

With TUSPIPE’s own coating technology and production lines, you can customise your  pipe coating to meet your production requirements.

Steel Fabrication

Pipelines are used to transport fluids such as vapors, gases, slurries, and powders at varying pressures and temperatures, and they are often subjected to extreme loads and strains. 

piping connections types
Pipe Fitting

Pipe fittings are a type of pipe system. Steel pipes, pipe fittings, flanges, bolts and nuts, washers, valves, and pressure-bearing elements of other piping components comprise the entire piping system.
