Hot-dip galvanizing (galvanizing), also known as hot-dip galvanizing, is an effective anti-corrosion metal, mainly used in metal structure facilities in various industries. Hot dip galvanized pipe is a kind of pipe whose inner and outer surfaces are galvanized. Zinc protects pipes from corrosion and makes them more durable. From construction to automotive manufacturing, hot dip galvanized pipe is the preferred choice of many professionals for its durability and resistance to corrosion.

Hot-dip galvanizing process:

Complete pickling—washing—adding auxiliary bath—drying—hanging plating—cooling—medicine—cleaning—polishing—finishing hot-dip galvanizing, which is developed from the ancient hot-dip galvanizing method and has been used in France since 1836. Industrial hot-dip galvanizing with a history of 140 years. However, in the past thirty years, the hot-dip galvanizing industry has been accompanied by the rapid development and large-scale development of cold-rolled strip steel.

Advantages of hot dip galvanized pipe:

Hot-dip galvanized steel pipe is a pipe coated with a layer of zinc. This coating helps protect the pipe from corrosion and other elements that can damage the pipe. The advantages of hot-dip galvanized steel pipe include:

1. Extended life: hot dip galvanized pipe has a longer life than other types of pipe because it is more resistant to corrosion and other damage.

2. Low maintenance: hot dip galvanized pipe requires less maintenance than other types of pipe because it is less prone to damage.

3. Cost-effective: hot dip galvanized pipe is more cost-effective than other types of pipes because it lasts longer and requires less maintenance.

4. Antistatic performance: By adding an antistatic agent to the formula, the internal and external surface resistance can reach and exceed the national industry standard

5. Flame retardant performance: The plastic raw materials used in the product are added with flame retardants. Its flame retardant performance index conforms to the national standard, and the steel-plastic composite structure has better flame retardant performance than pure plastic pipes and is suitable for underground and other flammable and explosive places.

Disadvantages of hot dip galvanized pipe:

1. The initial cost of hot-dip galvanized steel pipe is high.

2. Hot-dip galvanized steel pipes are more prone to corrosion than other types of pipes.

3. The strength of hot-dip galvanized steel pipe is not as good as other types of pipes.

4. Hot-dip galvanized steel pipe may be difficult to install.

What are the connection methods of hot dip galvanized pipe?

There are three main ways to connect hot-dip galvanized steel pipes. Different connection methods have different construction difficulties, performance, and construction methods.

1. Welded connection: Welded connection is the most widely used one, as long as the hot dip galvanized pipe is directly welded to the connection gap between two galvanized steel pipes. Its main advantages are: the interface is firm and durable, not easy to leak, the joint strength is high, the sealing is good, and it does not need frequent management after use. Although this connection method takes more time, the quality of the pipeline connection is the best. After the welding is completed, the pipe connection position is not easy to leak.

2. Card slot connection: Card slot connection is a popular one at present, and the construction will be simpler and more convenient, as long as two hot-dip galvanized steel pipes are processed into slots, and then connected with a card slot. Let's do it together. But the quality requirements for fixtures will be higher. If the quality of the clamp is not good, the connection is prone to water leakage, which will bring hidden dangers to users.

3. Flange connection: The connection structure of the flange connection is relatively simple. Use special flanges to connect two hot dip galvanized pipes together. However, the flange is easy to be damaged and loosened after being used for a long time. , resulting in water leakage at the connection, and the cost of the flange is generally cheaper, so it will increase the connection construction cost of the hot-dip galvanized steel pipe.

What aspects should be paid attention to when purchasing hot dip galvanized pipe?

1. When purchasing hot dip galvanized pipes, it is necessary to select hot-dip galvanized steel pipes of appropriate size and type for installation according to construction requirements and the actual installation environment. If the purchase is not correct, it will affect the construction quality and construction effect.

2. When purchasing hot dip galvanized pipes, it is also necessary to check in detail whether there are cracks, spots, depressions, etc. on the appearance of the pipes. If yes, it is not recommended to buy. This kind of pipe is an inferior product and is easy to be used later. There is a leak problem.

3. Determine the thickness of the galvanized layer. The thicker the zinc coating, the more corrosion-resistant the pipe.

4. Choose a Hot dip galvanized pipe with a seamless or welded design. Seamless pipes are more resistant to corrosion than welded pipes because they do not have any joints or seams where corrosion can occur.

5. In order to effectively avoid buying inferior hot-dip galvanized steel pipes, it is recommended that you purchase products from large-scale and reputable manufacturers, so that the quality of the products will be more guaranteed.

Hot-dip galvanized steel pipe products are made of high-quality steel, with high mechanical strength, strong pressure bearing capacity, excellent electrical insulation performance, high hardness and smooth inner and outer surfaces, low friction coefficient, good flame retardancy, low water absorption, and wide operating temperature range. . It combines the performance advantages of high-quality steel pipes and nano-coatings and is widely used in the construction of pipeline systems in industries such as electric power, communications, transportation, municipal, mining, petroleum, and chemical industries.
