Steel Tube

Spiral welded pipe is a special method of pipe manufacturing in which a steel coil is formed and welded using what is known as a DSAW method to create varying outside diameters and wall thickness of steel pipes. There are many advantages to spiral pipe and one of the main advantages is that different diameters can be made from the same steel coils and lengths can be custom made to fit any job requirement. At P.I.T. Pipe, we supply a complete variety of types and sizes of spiral pipe to meet all of your needs. We stock a huge selection and variety of sizes, lengths, diameters, and different types of spiral pipe including the most common sizes ranging from 18” to 126” in diameter and from .25” to 1” in wall thickness. We can even supply pipe in lengths up to 150’ long.

Thick-walled steel pipe, the steel pipe whose outer diameter to wall thickness ratio is less than 20 is called thick-walled steel pipe. It is mainly used for petroleum geology drilling pipe, cracking pipe, boiler pipe, bearing pipe, automobile, tractor, aviation high-precision structural pipe and so on.
The key to the quality of thick-walled steel pipe is the uniformity of wall thickness. If the wall thickness of thick-walled steel pipe is not controlled, it will directly affect the quality and use of steel pipe. Thick-walled steel pipe and large-caliber thick-walled steel pipe are generally used in various mechanical processing and thick-walled parts processing

The manufacturing methods of ASTMA106-99 High Pressure Steel Pipe are divided into hot rolling (extrusion, expansion) and cold drawing (rolling). High pressure steel pipe has good comprehensive mechanical properties at room temperature and high temperature, strict quality control, suitable for various working conditions under high pressure. High pressure steel pipe is mainly used in boiler, diesel engine high pressure tubing, fertilizer equipment and pipelines.
