Three major categories of DIN ST37 seamless steel pipes
With the progress of human civilization and the improvement of living standards, metal products are becoming increasingly popular. Stainless steel pipes have a 40 year development history and are a common type of stainless steel, also known as 18/8 stainless steel in the industry. Its corrosion resistance is superior to 430 stainless steel, with corrosion resistance, high temperature resistance, and good processing performance. Therefore, it is widely used in industrial and furniture decoration industries, as well as food and medical industries, such as some high-end stainless steel tableware, bathroom and kitchen utensils. Today, the editor will talk to you about the three different classifications of DIN ST37 seamless steel pipe, hoping to be helpful to everyone!
1： Stainless steel decorative tube
As the name suggests, stainless steel decorative tubes are stainless steel tubes used for decoration. The main materials are divided into 201, 304, and 316 stainless steel pipes, mainly used for stainless steel anti-theft windows, staircase handrails, guardrails, etc. It can also be divided into ordinary tubes, flower tubes, and color tubes by category.
Characteristics of ordinary pipes: simple production process, multiple varieties and specifications. Mainly stainless steel and brushed sanding.
The characteristics of stainless steel flower tubes: The appearance of flower tubes has changed the single appearance of traditional stainless steel tubes, which is refreshing.
The characteristics of colored stainless steel pipes: Apply a layer of color on the surface of the stainless steel pipes, any size can be used, and the corresponding processing cost can be increased by meters.
2： Stainless steel industrial pipe
Divided into seamless pipes and welded pipes
Production process: Large stainless steel welded pipes are welded using stainless steel strips, which are hot-rolled to a certain thickness and then extended to the required thin thickness. The inner wall of the stainless steel decorative tube has seams. Stainless steel seamless pipes are produced by cold drawing, with seamless pipe walls.
Pipeline surface: Xiyouwo stainless steel decorative pipe is a rolled and reprocessed pipeline, and the surface will be polished, so the pipeline surface is smooth and shiny. The surface of seamless pipes is often rough. Thickness difference: 304 stainless steel decorative tube has a relatively thin thickness, with a thickness of up to 0.2mm and a thickness of only 5.0mm. But seamless stainless steel pipes are generally thicker.
Application scope: Due to limited welding seams and thickness, but with good surface treatment, it is mainly used for civil decoration products such as building decoration products and stainless steel products. Stainless steel industrial pipes are seamless, with rough and thick pipe walls and strong compressive strength, mainly used for products that meet high pressure, high strength, and mechanical structures.
3： Stainless steel product pipe
Generally speaking, stainless steel pipe refers to the stainless steel pipe that needs to be customized by pipeline manufacturers, when the general stainless steel decorative pipe cannot meet the usage requirements. It can be refined into many different types according to the different needs of customers. Such as stainless steel furniture pipes, bathroom pipes, water pipes, mechanical equipment pipes, etc. Features: Strict requirements for specifications, positive and negative differences, surface brightness workmanship, etc., with requirements for bends, expansion, etc
The above is a little knowledge about the classification of DIN ST37 seamless steel pipes. I hope everyone likes it! We are a professional manufacturer of stainless steel pipes. If you need anything, please feel free to contact us!
