Stainless steel pipes are common pipes in engineering, and the most common ones are 201 and 304. They have advantages that other pipes cannot replace. They will be used more and more in engineering, and their use will become more and more popular, and their prospects are promising.

In some cases, stainless steel pipes have advantages, especially thin-walled stainless steel pipes with a wall thickness of only 0.6 to 1.2 mm. They are safe, reliable, hygienic, environmentally friendly, and economical in high-quality drinking water systems, hot water systems, and water supply systems that put safety and hygiene first. It has been proven by domestic and foreign engineering practices that it is one of the best comprehensive performance, new, energy-saving and environmentally friendly pipes in water supply systems.

Summary of types and uses of stainless steel pipes

1. Stainless steel decorative pipes

1. Material: mainly 201, 304, a small amount of 301, 316

2. Use: mainly decoration projects such as stairs, doors, windows and guardrails, and some products with lower requirements

3. Features: bright surface, brushed or frosted, negative difference

2. Stainless steel product pipes

1. Material: mainly 201, 304, 316

2. Use: bathroom, product piping, fluid pipes, etc.

3. Features: strict requirements on positive and negative difference of specifications, surface brightness and workmanship, and there will be requirements for bending, expansion and contraction

3. Stainless steel special-shaped pipes

When the number of special-shaped pipes is small, the round pipe secondary pressing pipe forming method is adopted (except for grooved pipes). If the number is large, it can be customized. Due to different specifications, sometimes there is a lack of molds, and the corresponding mold costs may need to be borne.

1. Oval tube: regular oval tube, flat oval tube

2. Grooved tube: round tube, square tube, rectangular tube, oval tube, etc. can all be grooved, generally used for guardrail frame glass

3. Others: triangle, handrail, arch, fan, door frame tube, etc.

Fourth, stainless steel pattern tube

The appearance of pattern tube has changed the single appearance of traditional stainless steel tube, which is refreshing. Recently, many pipe factories have launched pattern tube projects.

1. Ordinary embossing: traditional round tubes are pressed with gourd patterns

2. European embossing: the surface of the tube is pressed with patterns such as circular, auspicious clouds, and money

Five, colored stainless steel tube

A layer of color is plated on the surface of the stainless steel tube, any material specification is acceptable, and the corresponding processing fee is increased by square on the basis of the tube. In the past, it has been plated for less than four meters. Now gold, rose gold, and black titanium can be plated for 6 meters. Colored tubes need to reduce the probability of welding and use connectors.

6. Stainless steel composite pipe

1. Stainless steel composite pipe: In the past two years, composite pipes with 304 surface and 201 inner layer have appeared. Now that the price of 304 has dropped, composite pipes have become less common.

2. Carbon steel composite pipe: 201 or 304 surface, carbon steel inside, surface thickness below 1.0, generally used for highway guardrail projects.

7. Stainless steel industrial pipe

Industrial pipes also have welded pipes and seamless pipes, mainly used for engineering structures, various pipelines, etc.
