Seamless Pipe Specification

Product Details

Seamless steel pipes are made from perforated whole-round steel, and they do not have a weld seam on the surface. They are known for their strength, durability, and ability to withstand high pressure and temperature conditions.

Based on the production method, there are several types of seamless steel pipes:

Hot-rolled seamless steel pipes: These pipes are produced by heating a solid billet and then piercing it to form a hollow tube. They are commonly used in industries such as construction, oil and gas, and mechanical engineering.

Cold-rolled seamless steel pipes: These pipes are made by cold drawing and rolling a seamless steel tube, resulting in improved dimensional accuracy and surface finish. They are widely used in precision applications, such as automotive components and hydraulic systems.

Cold-drawn seamless steel pipes: Similar to cold-rolled pipes, these pipes are produced by cold drawing a solid tube through a die, resulting in a smoother surface and tighter dimensional tolerances. They are often used in applications that require high precision and superior surface quality.

Extruded seamless steel pipes: These pipes are created by pushing or pulling a solid billet through a die to form the desired shape and size. They are commonly used in the production of small-diameter pipes and special-shaped pipes.

Pipe jacking: This method involves pushing a seamless steel pipe through the ground using hydraulic jacks. It is primarily used for underground construction projects, such as installing utility pipes or creating tunnels.
