Products Description
Welded Spiral steel pipe for irrigation is made by steel coil, extrusion forming under the normal temperature. Spiral steel pipe, also known as spiral or helix spiral steel pipe, is a low-carbon steel or low-alloy structural steel strip at a certain helix angle (called molding angle) rolled into a tube, and the tube is made of welded. During molding process of spiral welded steel pipe, steel plate has uniform deformation and light residual stress, thus the surface has no scratches. Spiral steel pipe has more flexible thicknesses and diameters, especially in making high-grade thick pipes with small or medium aperture, these techniques has incomparable advantages in satisfying your needs. Spiral steel pipe in the production process if the production process is unreasonable, machine parameter settings shall be deemed to occur deviation phenomenon, especially large diameter spiral steel pipe, which is often said the wrong side of the phenomenon. The spiral welded pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. It is one of the twenty key products developed by China.
Welded Spiral steel pipe for irrigation for liquid transport use: water supply, drainage, sewage treatment works, mud transport, marine water transport. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: as a pile driving pipe, as a bridge; piers, roads, building structures, marine piling pipe. Spiral welded pipes undergo stringent physicochemical tests before they are put into use. Spiral seam submerged arc welded pipe for pressure-bearing fluid transportation is mainly used for pipelines conveying petroleum and natural gas. The steel pipe has strong pressure bearing capacity and good plasticity, which is convenient for welding and processing and forming. In general, spiral submerged arc welded steel pipe for low pressure fluid transportation adopts double-sided automatic Submerged-arc welded or single-sided welding method for submerged-arc welded steel pipes used for the transport of low pressure fluids such as water, gas, air and steam.

Products Advantages
● When the molding angle is modified, steel pipes of assorted diameters are often created exploitation of a similar breadth of strip steel, which facilitates the sort of transportation.
● Since the steel strips are ceaselessly sinuate, the length of the spiral tube isn't restricted, and also the length is often random.
● The attachment spiral is uniformly distributed on the circumference of the spiral pipe, that the spiral pipe has high dimensional accuracy and robust strength.
● Straight forward to alter the dimensions, appropriate for little batches, a lot of styles of production screw.
● Spiral steel pipes have a similar specification length as straight welded pipes, and also the wall thickness of a similar specification makes the spiral steel pipes stand up to the most pressure.
