Description
hot dip galvanized pipe |factory direct supply |Tianjin |YuantaiDerun
1.What's hot dip galvanized pipe?
In order to improve the corrosion resistance of Hot-dip galvanization steel pipes, general steel pipes are galvanized. Hot-dip galvanization steel pipe is formed by immersing the black pipe into the heated zinc bath, repeating several times, and finally taking out the steel pipe. The Hot-dip galvanization steel pipe has a thick hot-dip galvanized coating, strong anti-corrosion ability, and a rough surface. However, the service life of the steel pipe will be longer and the cost will be higher than that of ordinary galvanized steel pipe.
2. Hot-dip galvanized pipes price
Yuantai Derun is a direct wholesale manufacturer, so the price of hot-dip galvanized steel pipes is relatively low. Welcome to purchase. In addition to the low price, the quality of Yuantai's hot-dip galvanized steel pipes is also very reliable, with sufficient stock, complete specifications, and large production capacity, which can meet your one-stop procurement needs for hot-dip galvanized steel pipes.

4. Hot dip galvanized steel pipe load-bearing
Galvanized steel pipes can withstand around 20 kilograms. Generally speaking, it is 6 meters long, but some are also determined by the customer based on the rolling length, which is not easy to calculate without thickness. Formula: 0.02466 * wall thickness * (outer diameter wall thickness) Hot dip galvanized pipe is used to produce an alloy layer by reacting the molten metal with the iron substrate, thereby combining the substrate and coating. Hot dip galvanizing refers to the pickling of steel pipes first. In order to remove iron oxide on the surface of steel pipes, after pickling, the steel pipes are cleaned in ammonium chloride or Zinc chloride aqueous solution or mixed ammonium chloride and Zinc chloride aqueous solution tank, and then sent to the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The substrate of hot-dip galvanized steel pipes undergoes complex physical and chemical reactions with the molten plating solution, forming a corrosion-resistant and tightly structured zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so its corrosion resistance is strong.
Generally, the bearing pressure of Water gas transmission pipe is 1.6MPa, and the bearing pressure of seamless steel pipe is 2.0MPa. The pressure of steel pipe varies with the thickness of steel pipe. The bearing pressure of galvanized seamless pipe and galvanized straight seam pipe shall refer to the original pipe technical standards! Fire protection pipelines generally have a pressure of 6 kilograms, but there are few special requirements for 8 kilograms and 16 kilograms. GB straight seam welded steel pipe (which is the type that is measured in inches, some are galvanized pipes), usually with a maximum pressure of 10 kilograms. According to me, I forgot (please refer to the large hardware manual). Buried fire pipelines are generally seamless
5.Executive standards for hot-dip galvanized steel pipes
The execution standards for hot-dip galvanized steel pipes are mainly divided into two categories,
One type is international standards,
One type is domestic standards. The specific standards are as follows:
1. International standards:
STM 53/53M-20: A standard issued by the STM International Standards Committee in the United States, which specifies the requirements for black and hot-dip galvanized welded and seamless steel pipes used for conveying liquids and gases.
BS1387: A standard issued by the British Standards Institution that specifies the requirements for hot-dip galvanized welded and seamless steel pipes.
2. Domestic standards:
GB/T3091-2015: Welded steel pipes for low-pressure fluid transportation.
GB/T13793-2008: Straight seam welded steel pipes.
GB/T21835-2008: Dimensions and unit length weight of welded steel pipes.
