Manufacturer of anti-corrosion for water pipelines

Description :

　　The material and manufacturing factors of steel pipes: The material and manufacturing factors of steel pipes are the internal causes of pipeline corrosion, especially the chemical composition and microcrystalline structure of steel. The content of non-metallic components is high, such as S and P corrosion, and C and Si are prone to brittle cracking. The microcrystalline fineness grade is low, and cracks propagate along the grain, resulting in cracking. Adding trace amounts of nickel, copper, and chromium can improve corrosion resistance. During the manufacturing process of steel pipes, surface defects such as scratches, pits, micro cracks, etc. can also easily cause corrosion cracking.

No need for large baking equipment. Production method: Large caliber spiral welded pipe (double-sided submerged arc spiral welded pipe) is a spiral seam steel pipe made of strip steel coil as raw material, often formed by warm extrusion, and welded by automatic double wire double-sided submerged arc welding process. (1) The raw materials are strip steel coils, welding wire, and flux. Strict physical and chemical tests must be conducted before investment. (2) The head and tail of the strip steel are connected by single or double wire submerged arc welding, and automatic submerged arc welding is used for repair welding after being rolled into a steel pipe. (3) Before forming, the strip steel undergoes leveling, trimming, planing, surface cleaning, conveying, and pre bending treatment. (4) The use of an electric contact pressure gauge to control the pressure of the oil cylinders on both sides of the conveyor ensures the smooth transportation of the strip steel. (5) Adopting external or internal control roller molding. Each batch of three steel pipe heads must undergo a strict initial inspection system to check the mechanical properties, chemical composition, fusion condition, surface quality of the steel pipe, and undergo non-destructive testing to ensure that the pipe manufacturing process is qualified before it can be officially put into production.

Large caliber spiral pipe manufacturer's spiral steel pipe specification table: National standard spiral steel pipe, abbreviated as 9711.1 spiral steel pipe, 9711.2 spiral steel pipe, material classification: 16Mn material spiral steel pipe, Q345B spiral steel pipe, L245 spiral steel pipe, L360 spiral steel pipe, X40-X80 spiral steel pipe, main applications: spiral steel pipe for sewage treatment, spiral steel pipe for water purification, spiral steel pipe for water plants, spiral steel pipe for power plant chemical enterprises, spiral steel pipe for nuclear power, spiral steel pipe for conveying flammable fluids, spiral steel pipe for conveying non flammable fluids, national standard spiral steel pipe, and spiral steel pipe for the Ministry of Petroleum. This product is made of hot-rolled steel strip as raw material, formed by constant temperature spiral forming, and welded by automatic submerged arc welding process. The product follows the standard. Mainly used for transporting flammable and non flammable fluids and steel structures in the petroleum and natural gas industry. Spiral welded pipes are divided into single-sided submerged arc welding and double-sided submerged arc welding: single-sided submerged arc welding: The forming methods of single-sided welding are divided into forced forming and free forming. Currently, forced forming is generally used, usually using ceramic pads. When welding steel bars, the welding of two steel bar joints where only one side (or side) of the joint is welded is called single-sided welding. The welding length is 10 times d (d is the diameter of the steel bar). For example, when two steel bars with a diameter of 25 millimeters are overlapped, the length of the weld seam should reach 25 centimeters or more. The minimum thickness of the weld seam is 0.05d. The minimum width of the weld seam is 0.1d to meet the welding requirements. Double sided submerged arc welding: Double sided submerged arc welded pipes use double-sided submerged arc spiral welding technology to continuously weld narrow strip (plate) coils into steel pipes. It has been widely used in oil and gas long-distance pipeline projects such as the West East Gas Pipeline in China, and is the main pipe type used in China's oil and gas long-distance pipeline projects.

It is a two-component coating of A (epoxy) and B (curing agent), which has excellent adhesion, toughness, moisture resistance, water resistance, chemical resistance, and the ability to prevent various ions from passing through the paint film. It has the characteristics of expansion and contraction with the coated object. The paint film never falls off or cracks. The manufacturer of IPN8710 anti-corrosion steel pipe with a thickness of 0.5-1.0mm believes that with the increase of population, rapid economic development, and higher requirements for ecological environment quality, insufficient water resources have become a serious bottleneck constraint. Manufacturers are creating a new vision of green and anti-corrosion. "The way to solve the water resource crisis is to open up new sources and reduce costs. As far as China's current development stage and level are concerned, reducing costs should be the primary way." Li Guoying, Deputy Minister of Water Resources, pointed out that agriculture is a major water user and an industry with great potential for water conservation. Vigorously developing water-saving irrigation is an inevitable choice to alleviate the contradiction between water supply and demand. It is reported that by the end of 2013, the effective irrigated area in China had reached 9. 5.2 billion acres, of which water-saving irrigation projects account for about 43% of the effective irrigation area. The high-efficiency water-saving irrigation areas such as low-pressure pipeline water delivery, sprinkler irrigation, and drip irrigation account for about 22% of the effective irrigation area. There are many types of corrosive media in the water supply pipeline, including acid, alkali, salt, oxidant, and water vapor. The coating must have chemical inertness, acid and alkali salt corrosion resistance, and the coating should have a dense structure, good waterproof permeability, strong adhesion, toughness, and fullness. This product belongs to the category of "chemical reactive" coatings and is packaged in two components. Component A consists of resin and initiator, while component B consists of active monomer and catalyst. So before use, the two components must be weighed and proportioned according to the specified important ratios, mixed and stirred evenly, and cured for 30 minutes according to the specified time before application. The cured coating should be used up within 6-8 hours to avoid waste of bonding. The ratio is as follows: primer, component A: component B=1 barrel: 1 barrel. Please strictly follow the required ratio (or apply according to the ratio notified by the manufacturer at that time) for the topcoat, with component A: component B=1 barrel: 1 barrel. Please strictly follow the required ratio (or construct according to the ratio informed by the manufacturer at that time) after applying one coat of paint, wait for more than 24 hours before applying the second coat of paint. After use, the packaging lid of the paint must be tightly sealed to prevent it from deteriorating due to moisture, alcohol, and water. The paint film can only be put into use after being applied at room temperature and dried at room temperature for 7-10 days.
