What is the difference between thick wall tube thin wall tube?

As the name suggests, the difference between thick wall pipe thin wall pipe is the difference of steel pipe wall thickness.

Similarities: the thin-walled tube material is food grade stainless steel, stable non rusting, with excellent stainless steel corrosion performance good intergranular corrosion resistance, service life up to 70 years, maintenance free no need to update.

In terms of production technology, all thin-walled steel tubes are cold drawn, while thick walled steel tubes are generally hot drawn. If the unit of measurement is used to distinguish, it is generally considered that the wall thickness / pipe diameter equal to 2mm is stainless steel thick wall. The watershed between pipe thin-walled steel pipe is thin-walled steel pipe, whose wall thickness / pipe diameter is less than 2mm, whose wall thickness is larger. In application, thin-walled steel pipe is mainly used for pipeline. Stainless steel thick wall pipe is mainly used for poor materials of hollow parts. For pressure important piping.

Thick wall pipe is a kind of general stainless steel material, its anti rust performance is stronger than 200 series stainless steel material. High temperature resistance is good, the general temperature limit is below 700 ℃. It has excellent corrosion resistance of stainless steel good intergranular corrosion resistance. For oxidizing acid, it is found that the stainless steel thick wall tube has strong corrosion resistance when the concentration of nitric acid is less than equal to 65% of boiling temperature. It also has good corrosion resistance to alkaline solutions most organic inorganic acids.

On the application

Stainless steel thick wall pipe has good corrosion resistance, heat resistance, low temperature strength mechanical properties. It is resistant to atmospheric corrosion. If it is an industrial environment seriously polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage transportation. It has good machinability weldability. Plate heat exchanger, bellows, household products, building materials, chemical industry, food industry, etc

Thin walled stainless steel pipe is only widely used in home decoration, construction sites, domestic hot cold water, direct drinking water other water supply drainage projects, municipal water supply other projects, but also suitable for natural gas transmission as gas system fire protection system. The company's application fields are hospitals, schools, gymnasiums, residential buildings, shopping malls office buildings.
