AISI 4140 cold drawn and hot rolled alloy seamless steel pipe

Seamless steel pipe is a type of steel pipe that is perforated from a whole round steel and has no welds on the surface. According to the production method, seamless steel pipes are divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes,cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. Seamless steel pipes are divided into two types:round and special-shaped according to the cross-sectional shape.

Hot-rolled seamless steel pipes are further divided into general steel pipes, stainless steel pipes, high-pressure boiler steel pipes, medium-pressure boiler steel pipes, low-pressure boiler steel pipes, petroleum cracking pipes, alloy steel pipes,geological steel pipes and other steel pipes. In addition to alloy steel pipes, general steel pipes, petroleum cracking pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, stainless steel pipes, and other steel pipes,cold-rolled seamless steel pipes also include stainless thin-walled steel pipes, carbon thin-walled steel pipes, and alloy thin-walled steel pipes. Wall steel pipes and special-shaped steel pipes.

Seamless steel pipes are used in a wide range of applications, including structures, fluid transportation, low and medium pressure boilers, high pressure boilers, fertilizer equipment, oil cracking, geological drilling, diamond core drilling, oil drilling,ships, automotive half-shaft casings, diesel engines, etc. , seamless steel pipes will be used, and the use of seamless steel pipes can avoid problems such as leakage, ensure the use effect and improve the utilization rate of materials.It can be seen that the application of seamless steel pipes mainly reflects three major fields. One is the construction field,which can be used for underground pipeline transportation, including groundwater extraction when building buildings. The second isthe processing field, which can be used in machining, bearing sleeves, etc. The third is the electrical field, including pipelines for gas transmission and fluid pipelines for hydropower generation.
