Thin-walled stainless steel pipe celery companion uses:The thin-walled stainless steel surface is as bright as a mirror, silver shining, especially suitable for kitchen and bathroom water pipes when the old house is renovated, there is no need to knock on the wall to remove the old water pipe, just put the thin-walled stainless steel water pipe on the surface of the wall, not only beautiful and luxurious, but also use the water pipe as a shower curtain rod and towel rack.

The high strength of thin-walled stainless steel water pipes greatly reduces the possibility of water leakage affected by external forces, significantly reduces the leakage rate of water, and enables water resources to be effectively protected and utilized.

Seamless steel pipes are divided into two types: hot-rolled and cold-rolled (dialed) seamless steel pipes.

Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

In addition to general steel pipes, low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other steel pipes, cold-rolled seamless steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless steel thin-walled steel pipes, and special-shaped steel pipes. The outer diameter of the hot-rolled seamless pipe is generally greater than 32mm, the wall thickness, the diameter of the cold-rolled seamless steel pipe can be up to 6mm, the wall thickness can be reached, the outer diameter of the thin-walled pipe can be up to 5mm, the wall thickness is less than, and the cold-rolled has higher dimensional accuracy than hot-rolled. Seamless tubes for furnaces, heat exchangers and pipes in petroleum refineries.

It is commonly used to make high-quality carbon steel), alloy steel (12CrMo, 15CrMo), heat-resistant steel (12Cr2Mo, 15Cr5Mo), and stainless steel (1Cr18Ni Cr18Ni9Ti). In addition to the chemical composition and various mechanical properties of the steel pipe, it is also necessary to ensure the water pressure, flattening, flaring and other tests, as well as surface quality and non-destructive testing. The steel pipes are delivered in a heat-treated condition.

Stainless steel pipes: with a variety of stainless steel hot-rolled, cold-rolled stainless steel pipes, widely used in petroleum, chemical equipment pipelines and stainless steel structural parts for various purposes, in addition to ensuring the chemical composition and mechanical properties, all steel pipes used to withstand fluid pressure should be guaranteed to be qualified in hydraulic pressure. All kinds of special steel pipes should be guaranteed according to the regulations.

The ratio of the outer diameter of the steel pipe to the wall thickness is greater than 20 is called a thin-walled steel pipe. Thin-walled steel pipesThin-walled steel pipes are made by cold drawing. Among them, carbon steel, low-alloy steel and alloy steel thin-walled pipes are suitable for general structures and mechanical structural parts; Thin-walled fluid steel pipes are used to transport general fluids; Stainless steel thin-walled pipes are used in heat-resistant containers, transportation pipelines and mechanical structural parts in chemical, petroleum, light industry, food, machinery and instrumentation and other industries.

Thin-walled pipes are made of steel ingots or solid tube blanks perforated to make capillaries, and then made by hot rolling, cold rolling or cold dialing. Thin-walled pipes have an important position in China's steel pipe industry. The raw material of the thin-walled tube is a round tube blank, which is cut by a cutting machine and processed into a blank with a length of about 1 meter, and sent to the furnace for heating by a conveyor belt.
