Stainless steel pipe is a type of pipe widely used in industry, construction, roads and other fields. It is popular due to its durability, corrosion resistance, and easy cleaning. However, the quality and performance of stainless steel pipes produced by different manufacturers on the market are not the same. How to choose high-quality stainless steel pipes has become a problem for many users.
This article will introduce stainless steel pipe selection tips to help readers choose high-quality stainless steel pipes. 1. Material selection
316 stainless steel is a material with high strength, high corrosion resistance and high temperature resistance, and can adapt to a wide range of heat treatment methods. The main feature of 316 stainless steel pipe is its strong corrosion resistance, especially in chloride environments. Therefore, 316 stainless steel pipes are often used in marine facilities, chemical equipment, pharmaceutical industries, etc.
304 stainless steel pipe is an alloy material with high corrosion resistance, wear resistance and excellent processability. 304 stainless steel pipe is mainly used in chemistry, mining, food processing and medical equipment. Due to its good toughness, strength and oxidation resistance, it is a high-quality material widely used in pressure vessels, pipes and pipe fittings.
201 stainless steel pipe is also a relatively common stainless steel pipe on the market and is mainly used in manufacturing various daily necessities. It has excellent corrosion resistance and precision machining performance, especially in terms of rigidity and hardness compared with 304 stainless steel. However, 201 stainless steel is still far inferior to 316 stainless steel and 304 stainless steel in terms of corrosion resistance, oxidation resistance, and strength.
2. Wall thickness selection
Wall thickness is one of the important factors to measure the performance of stainless steel pipes. Its size directly affects the service life and load-bearing capacity of stainless steel pipes. When selecting the thickness of stainless steel pipes, various factors such as the use environment, temperature and pressure of the pipe should be taken into consideration, and the appropriate wall thickness should be selected according to actual needs. Generally speaking, as the wall thickness increases, the load-bearing capacity of the pipe will also increase, but it will also increase the cost.
3. Surface finish selection
The surface finish of stainless steel pipes is one of the important signs of its quality. It directly reflects the quality, processing accuracy and other factors of the internal and external surfaces of the pipe. Generally speaking, the better the surface finish, the better its corrosion resistance and strength will be. Therefore, when selecting stainless steel pipes, you should pay attention to its surface. If you find obvious defects such as pitting, scratches or oxidation spots, you should reject it. 4. Production process selection
The production process of stainless steel pipes is one of the important factors that determine their quality. High-quality stainless steel pipes should have the characteristics of high precision, high purity, and high-quality craftsmanship, which can ensure consistent wall thickness, high hole diameter accuracy, and good surface finish.
