This article will introduce the entire process of stainless steel ERW pipe production technology and its application, providing readers with detailed background information and reference materials. The stainless steel ERW pipe production process refers to processing steel plates into pipes through resistance heating. This kind of pipeline has the characteristics of beautiful appearance and long service life, and is widely used in construction, chemical industry and other fields.
The starting step of the stainless steel ERW pipe production process is the selection and preparation of raw materials. Raw materials should be inspected and classified before cutting and fastening. In addition, attention should be paid to the choice of raw material thickness and aspect ratio.
② Welded pipe making
The raw materials are processed into the shape that needs to be formed at the end, and then made into stainless steel pipes with a certain outer diameter and wall thickness. In the process of preparing stainless steel pipes, the process requirements must be strictly followed.
③ Welding and steel pipe adjustment
After completing the pipe making process, the steel pipe needs to be adjusted, including rolling and straightening of the steel pipe, to ensure that the size, hardness and strength of the steel pipe meet the requirements.
④ Processing and testing
The finished stainless steel pipes require surface treatment and steel pipe testing to ensure that the quality of the steel pipes meets standard requirements and can be used normally.
② Water treatment field
Stainless steel ERW pipe is also widely used in the field of water treatment, such as urban drainage pipes, water supply pipes, etc. This kind of pipeline has the characteristics of corrosion resistance and antibacterial in water treatment, and can meet the strict requirements of water treatment on pipeline materials.
③ Chemical industry
Stainless steel ERW pipe is also widely used in the chemical industry, such as oil and gas transportation pipelines, fertilizer production pipelines, etc. It has the characteristics of high temperature, high pressure, corrosion resistance, etc., and can meet various requirements for pipeline materials in the chemical industry.
(1) High precision
Stainless steel ERW pipe has the advantage of high precision. This is due to its mechanical processing method, which has high requirements for dimensional accuracy and can control the error range within a good range.
(2) Beautiful appearance
Stainless steel ERW pipe has a beautiful appearance, high brightness and color, and is unmatched by other pipe materials.
(3) Strong adaptability
Stainless steel ERW pipe has the advantage of strong adaptability. It is not only suitable for use under normal temperature and normal pressure conditions, but also suitable for use under high temperature, high pressure, strong corrosion and other environments.
② Disadvantages
Since there are certain oxides inside the stainless steel ERW pipe, there is a risk of melting at high temperatures.
Stainless steel ERW pipe production technology and its application have become an important part of modern industry. As a pipe material with excellent properties, stainless steel ERW pipe will be widely used in construction, water treatment, chemical industry and other fields. Although stainless steel ERW pipe still has some defects, its future market prospects are still very optimistic.
