Our factory is over 70000 square meters. We are a professional manufacturer and exporter of steel products. The main products are pre-galvanized steel pipes, hot-dip galvanized pipes, welded steel pipes, square rectangular pipes and scaffolding products. We applied for and obtained 3 patents. These are grooved pipe, shoulder pipe and Victaulic pipe. Our manufacturing facilities include 4 pre-galvanized production lines, 8 ERW steel pipe production lines, and 3 hot-dip galvanized production lines. According to GB, ASTM, DIN, JIS standards. The products have passed the ISO9001 quality certification.

Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.

Galvanized steel pipe is a welded steel pipe with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensing pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc.

The hot-dip galvanized pipe reacts the molten metal with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so it has strong corrosion resistance.

Galvanized steel pipe connection: threaded, welded.
Roll groove connection
(1) Roll groove weld cracking
1. Grind the welding ribs on the inner wall of the grooved part of the nozzle to reduce the resistance of the rolling groove.
2. Adjust the axis of steel pipe and rolling groove equipment, and require the level of steel pipe and rolling groove equipment.
3. Adjust the speed of the grooving, the forming time of the grooving should not exceed the specified time, and the force should be applied evenly and slowly.
(2) Roll groove steel pipe fracture
1. Grind the welding ribs on the inner wall of the steel pipe nozzle pressure groove to reduce the resistance of the rolling groove.
2. Adjust the axis of the steel pipe and the rolling groove equipment to require the level of the steel pipe and the rolling groove equipment.
3. Adjust the speed of the groove, the speed of the groove cannot exceed the specified, and the force is applied evenly and slowly.
4. Check the width and type of the support roller and pressure roller of the grooving equipment, and check whether there is any bite phenomenon caused by the size mismatch between the two rollers.
5. Use a vernier caliper to check whether the groove of the steel pipe is specified.
(3) The groove formed by the rolling groove machine shall meet the following requirements
1. The surface from the pipe end to the groove section should be smooth without unevenness and rolling marks.
2. The center of the groove should be concentric with the pipe wall, the width and depth of the groove should meet the requirements, and check whether the type of the clamp is correct.
3. Apply lubricant to the rubber sealing ring and check whether the rubber sealing ring is damaged. The lubricant must not be oil lubricant.

Process flow:
The hot-dip galvanized pipe is to make the molten metal react with the iron matrix to form an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing refers to the pickling of steel pipes. In order to remove iron oxide on the surface of the steel pipe, the pickled steel pipe is washed in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous ammonium chloride and zinc chloride aqueous solution tank, and then sent to a hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel pipe substrate undergoes complex physical and chemical reactions with the plating solution to form a dense corrosion-resistant zinc-iron alloy layer.

application:
Mainly used in agricultural machinery, grain storage, high-speed guardrail and other industries. Its outstanding features are low cost and high added value. Galvanized steel pipes are also used in building materials, home appliances, automobiles and other industries, because these industries are more or less involved in the support of steel structures, and the appearance of galvanized steel pipes solves this problem ingeniously. I believe its demand will continue to increase in the future. In addition to being widely used in industrial production, galvanized steel pipes also play an important role in modern buildings, factories, space structures, transportation and energy. The application of galvanized steel pipe in these fields mainly plays the role of protective film to weaken the external corrosion of objects.

Our annual output of various pipes is more than 300,000 tons. Our products are widely used in machinery, steel structures, agricultural vehicles and greenhouses, automobile industry, railways, road guardrails, container internal structures, furniture and steel fabrics. Our company has domestic first-class professional and technical consultants and excellent professional and technical personnel, and our products are exported to all over the world. We believe that our high-quality products and services will be your best choice, hope to gain your trust and support, and sincerely look forward to long-term and good cooperation with you.
