The surface of galvanized steel pipes in Henan Province is welded with hot-dip or electro-galvanized steel pipes. Galvanizing increases the corrosion resistance of steel pipes and extends their service life. The use of galvanized pipe is very wide. Except for the line pipe of general low pressure fluid such as water, coal gas, oil, etc., it is also used as oil well pipe and oil pipe of petroleum industry, especially offshore oil field, and oil heater and condensation of chemical coking equipment. Cooler, coal distillate oil exchange pipe, and trestle pipe piles, mine pit support frame pipe.

stainless steel pipe
1. Usage: transport pure water and corrosive production wastewater.
2, advantages and disadvantages: the appearance of the United States, corrosion resistance. Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetallic composite pipes, coatings, and coated pipes that meet the special requirements in order to save precious metals. . Stainless steel pipes have a wide range of types and different uses. Their technical requirements are different, and production methods are also different. The current production of steel pipe diameter range of 0.1-4500mm, wall thickness range of 0.01-250mm. In order to distinguish its characteristics, the steel pipes are generally classified as follows
