Brief introduction of thinner wall steel pipe

The steel pipe that is widely used in our daily life such as China hollow section is galvanized commonly. Nowadays, thinner wall steel pipe become more and more popular among customers. However, do you know what is thinner wall steel pipe? Actually, thick wall steel pipe refers to the pipe diameter and wall thickness ratio of less than 20. That means the pipe diameter as well as wall thickness ratio of thick walled steel pipe is less than 20. They are mainly used in petroleum geology drilling pipe, the petrochemical cracking tube, boiler tubes, the bearing tube as well as automobiles, tractors, aviation high-precision structural tube. However, do you know the biggest difference between thick wall steel pipe and thin wall steel pipe? Obviously, pipe wall thickness make difference. Generally, diameter equals to 0.02 is thick.

The key of quality for thick wall steel pipe should be thickness uniformity. However, the key of quality for hot dipped galvanized steel pipe is thick and uniform zinc coating. Its corrosion-resistant property is stronger and it will be applied to the greenhouses, gas or steam,etc. In addition, it has long service life and a large number of electric wires need to be protected by hot dip galvanized steel pipe.

Welding thick-walled steel pipe firstly clean oil, paint, water, rust,etc. Customers should inspect it on a regular basis. If the pipe be layered, at least two layers, the first layer of the whole circle should be welded. Do you know how to purchase it? There are two methods. The first one is that you can consult China steel tube manufacturer and then purchase it from owner’s factory directly which can have some discounts offered by steel pipe suppliers. The other way is online deal which is much more convenience without the barrier of region and time. While you may assume potential risks in pipe quality as pipe suppliers are multiple and it is quite difficult to identify better one. No matter which way to choose, early preparation in information and pipe knowledge is necessary.

The most common pipe shape for thinner wall steel pipe is round that called circular hollow section. In general, thinner wall steel pipe is a kind of cold rolled steel pipes that is higher in pipe price than that of hot rolled steel pipes. Different countries have different standards for welding steel pipes. For a more detailed understanding, you can search for these aspects.
