75 Galvanized steel pipe more than one meter

As we all know, galvanized steel pipe is widely used in engineering, high strength, and corrosion resistance is also strong, but there are many people on galvanized steel pipe is not very understanding, the 75 galvanized steel pipe one meter multiple?

One, 75 galvanized steel pipe more than one meter

A meter is 15 kilograms. 75 steel pipe refers to the national standard DN75 steel pipe, and the national standard DN75 steel pipe is 85 mm, the wall thickness is 3.5 mm, the weight is 15 kg per meter. But the steel pipe has seamless steel pipe and welded steel pipe, usually 40 steel pipe is seamless steel pipe, in the production process is to put the solid tube billet or steel ingot through the hollow tube, rolling it into the required size of steel pipe. In addition, the use of perforation and rolling methods are different from the direct composition of seamless steel pipe in different ways.

Two, how to buy galvanized pipe

1. Look at the specification and size

Because of the different types of galvanized pipe, the support force is different, its price is also different, so in the purchase of galvanized pipe, the type and specifications are very important, once the wrong support force can not achieve the desired effect, so it will spend more time and costs.

2. Look at the price of steel

When purchasing galvanized pipe, there are usually two evaluation methods. If the purchase amount is small, it must be based on the situation to purchase. That is to say, the price of a root, in this case, the merchant will first calculate, then the price will be a little high. If you buy a large amount, the weight of the steel pipe will be multiplied by the price of steel so it will be more affordable.

3. look at the quality of detection

When purchasing galvanized pipe, choose smooth surface and burr free fracture to ensure pipe quality. In addition, the corrosion resistance of galvanized pipe is very important, which determines the performance of galvanized pipe. When selecting the type, we must confirm whether the corrosion resistance of steel can meet the corresponding requirements. To remind us, when buying steel pipe, we must choose large manufacturers to have more protection.
