FAQs

What is the difference between galvanized square steel pipes and carbon steel welded tubes?

I. Difference in appearance

Carbon steel pipe and galvanized steel pipe have some differences in appearance.

1. Carbon steel pipe is usually black, simple and plain. 2.

2. Galvanized steel pipe is coated with a layer of zinc, which gives it a silvery white color. The zinc coating prevents the pipe from rusting when exposed to air for long periods of time. At the same time, the appearance of the zinc layer also has a certain aesthetic.

Second, the difference in use

There is also a difference between carbon steel pipe and galvanized steel pipe in the field of application.

1. Carbon steel pipe is widely used, mainly used for transportation of various liquids, gases, solids, etc., such as oil, natural gas, water, chemical industry and other fields.

2. Galvanized steel pipe is usually used for outdoor applications related to wet environment, such as rainwater pipes, roof drains and so on in the construction industry.

Third, the performance difference

Carbon steel pipe and galvanized steel pipe also differ in performance.

1. Carbon steel pipe is stronger and easier to weld. In addition, carbon steel pipe can be used for high temperature and high pressure transportation.

2. Galvanized steel pipe shows certain advantages in corrosion, wear resistance, etc., and has better corrosion resistance, so it is more durable for outdoor use and more suitable for transportation and installation in complex environments.

Through the above analysis, I believe that you have a clearer understanding of carbon steel pipe and galvanized steel pipe, you can choose the appropriate material based on the specific needs and use of the occasion, to play its unique role.

How can I ensure the quality of galvanized square steel pipes and carbon steel welded tubes?

Control from five aspects: people, materials, machines, methods and environment.

①Human factor is the focus of welding control. Therefore, before welding, skilled welders with welder's license should be selected for necessary technical training and briefing. They shall not be replaced arbitrarily to ensure the relative stability of pipeline welders.

② Welding material control: ensure that the purchased welding consumables from formal channels, quality assurance certificates and certificates, in line with the process requirements; strict control of the electrode head recycling control, to ensure the flow and flow; welding consumables must be baked in strict accordance with the process, a single issue of no more than half a day's supply.

③ Welder: the welder must ensure reliable performance to meet the needs of the process; the welder must have qualified current and voltmeter to ensure the correct implementation of the welding process. Welding cable should not be too long, too long should be adjusted welding parameters.

④ Welding process methods: ensure the strict implementation of special operating methods for galvanized pipes, check the welding process before welding, control the welding process parameters and operating methods, check the appearance quality after welding, post-weld inspection. -Add weld nondestructive testing if necessary. Control the welding level and the number of welding consumables per pass.

⑤ Welding environment control: Ensure that the temperature, humidity and wind speed during welding meet the process requirements.

Galvanized welded pipe, also known as galvanized steel pipe, is divided into hot-dip galvanized and electro-galvanized. Welded pipe, as the name suggests, is a weldable steel pipe.

Are there any certifications I should look for when selecting a manufacturer or supplier?

Business license, tax registration certificate, organizational code certificate, and safety production permit. Three system certification: quality, environment, occupational safety and health management. Some industries also require qualification level certificates.

Can galvanized square steel pipes and carbon steel welded tubes be customized to meet specific project requirements?

Yes,It can be customized.

How long does it take for the products to be delivered after placing an order?

If there is stock available, it usually takes 3-5 days to ship. If there is no stock available, it will take 10 to 35 days for production, depending on the quantity of steel pipes ordered.
