When selecting a fluid pipe, it is necessary to consider its material, size, wall thickness and other factors. The tensile speed of the fluid pipe has an impact on the test results, and the stress rate control or load control is generally selected in the elastic section. Fluid pipes are widely used in various industries, such as construction, machinery, chemical industry, etc.
Line pipe is a kind of pipeline used to transport gas, liquid and solid, which is widely used in oil, natural gas, chemical industry, electric power and other fields.
Seamless tubes for furnace tubes, heat exchanger tubes and pipelines in petroleum refineries. Commonly used excellent carbon steel (10, 20), alloy steel (12CrMo, 15CrMo), heat-resistant steel (12Cr2Mo, 15Cr5Mo), stainless steel (1 Cr18Ni9, 1 Cr18Ni9Ti) manufacturing.
High-pressure fertilizer pipe is a kind of steel pipe used for fertilizer production and transportation, which has the characteristics of high strength and high corrosion resistance. The production process of high-pressure fertilizer tube includes tube blank inspection, peeling, heating, perforation, pickling, cold drawing, solid solution treatment, pickling passivation and other steps.
