First, the anti-corrosion structure of anti-corrosion steel pipe Anti-corrosion generally consists of three layers: the first layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170 ~ 250um, the third layer of polyethylene (PE) 2.5 ~ 3.7mm. the actual operation of the three materials will be blended into a single entity, through the processing of the steel pipe to make it a solid combination of the formation of excellent corrosion protection layer. The processing method is generally divided into winding type and round mold coating type two.

1. Role of coating materials In order to prevent rusting, the outer surface of steel pipe is coated. Rust on the surface of steel pipe will affect the actual use effect, quality and appearance image. Therefore, the coating process of steel pipe has a great influence on the quality of steel pipe products. 2. Requirements of coating materials

Galvanized square pipe is a kind of with hot-rolled or cold-rolled galvanized steel strip or galvanized coil as a billet, after cold bending processing and forming, and then by high-frequency welding made of hollow square cross-section type steel pipe. Or will be made in advance of the cold bending hollow type steel pipe and then processed by hot dip galvanized galvanized.

The method of checking the material of pipe fittings The material of stainless steel pipe fittings is crucial to their quality. When using stainless steel pipe fittings, you can assess its material by the following methods. Check the glossiness and surface smoothness of this piece by observation and touch. The surface of high-quality stainless steel fittings should be glossy and smooth, while poor-quality fittings may show dullness and roughness.

Stainless steel pipes often require welding during use. To ensure their performance, especially in special work environments, protection measures are necessary. Here's how to protect stainless steel pipes during welding:

In the stainless steel industry, nitrogen is often used, especially in the welding process of stainless steel welded pipes. Many wonder why this is necessary. Here's an explanation:

Common issues can be categorized into three types: uneven coating, dripping of the anti-corrosive agent, and bubbling of the anti-corrosive agent. (1) Uneven Coating: This issue occurs when the anti-corrosive agent is unevenly distributed on the steel pipe surface. Some areas have a coating that is too thick, leading to waste, while other areas are too thin or not coated at all, reducing the pipe's anti-corrosion ability and leading to rust. (2) Dripping of the Anti-Corrosive Agent: This happens when the anti-corrosive agent solidifies on the steel pipe surface like water droplets. While it does not directly impact corrosion resistance, it affects the pipe's appearance, making it look dull and uneven. (3) Bubbling of the Anti-Corrosive Agent: Air trapped in the anti-corrosive agent forms bubbles of various sizes on the steel pipe coating. Larger bubbles can be easily popped, compromising the coating's thickness and reducing its anti-corrosion capability, which leads to rust at the affected areas.

Seamless pipes are inseparable from our lives. In fact, they are needed to transport water, gas, natural gas or solid materials in our daily lives. Therefore, without seamless steel pipes, our lives will become very inconvenient. Here are some maintenance methods for seamless pipes.
