The characteristics and uses of welded pipes
Welded pipe, as the name suggests, is a pipe made by rolling steel plates or strips into a tubular shape through welding technology and welding them together. Welded pipes have the following significant characteristics:
a. High production efficiency: The production process of welded pipes is relatively simple, which can achieve continuous and automated production, greatly improving production efficiency.
b. Low cost: Due to the relatively simple production process and high material utilization rate of welded pipes, their cost is relatively low, making them suitable for large-scale, low-cost application scenarios.
c. Diverse specifications: Welded pipes can be produced according to different diameters, wall thicknesses, and lengths to meet various engineering needs.
Welded pipes are widely used in fields such as construction, bridges, pipeline transportation, and mechanical manufacturing. In the field of construction, welded pipes are commonly used in steel structure frames, supports, and protective railings; In the field of pipeline transportation, welded pipes are used to transport fluid media such as water, gas, and oil.
The characteristics and applications of seamless steel pipes
Seamless steel pipes are made through processes such as perforation, hot rolling, cold drawing, or cold rolling, and there are no welds on the pipe wall. Seamless steel pipes have the following significant characteristics:
a. Strong pressure bearing capacity: Due to the absence of welds in seamless steel pipes, their overall structure is more uniform, thus having higher pressure bearing capacity, suitable for use in harsh environments such as high pressure and high temperature.
b. High precision: The inner and outer walls of seamless steel pipes are smooth, with high dimensional accuracy, suitable for situations with high requirements for fluid resistance and flow control.
c. Good corrosion resistance: Seamless steel pipes can use special materials and surface treatment techniques to improve their corrosion resistance and extend their service life.
Seamless steel pipes are widely used in fields such as petroleum, chemical, power, and nuclear energy. In the petroleum industry, seamless steel pipes are used in key parts such as oil well drilling and oil and gas transportation pipelines; In the chemical industry, seamless steel pipes are used for corrosion-resistant and high-temperature resistant pipeline systems.
