You can rest assured to buy Pengfa Steam Insulation Steel Pipe from our factory. T In the thermal insulation steel pipe production line, the steel pipe is first sent to the cleaning equipment for cleaning, and then into the preheating equipment, heating to a certain temperature, so as to spray the anti-corrosion layer. Next, the anti-corrosion layer is coated on the outer wall of the steel pipe in the spraying equipment. The anticorrosive layer can be made of polyethylene, epoxy, three-layer PE and other materials, so that the steel pipe has good resistance to corrosion.
You can rest assured to buy Pengfa Thermal Insulation Steel Pipe from our factory. The insulation layer is made of rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3. It is fully filled with the gap between the steel pipe and the sleeve, and has a certain bonding strength, so that the steel pipe, the sleeve and the insulation layer form a solid whole. Polyurethane insulation tube foam has good mechanical properties and insulation properties. Generally modified or combined with other insulating materials, it can withstand 120℃ and 180℃

T Thermal insulation steel pipe is widely used in liquid gas transmission pipe network, chemical pipe insulation engineering, petroleum, chemical industry, central heating pipe network, air conditioning ventilation pipe, municipal engineering, high temperature prefabricated directly buried thermal insulation pipe is a kind of good thermal insulation performance, safe and reliable, low engineering cost of direct buried thermal insulation pipe. The utility model effectively solves the problems of insulation, sliding lubrication and waterproofing of pipe end of prefabricated directly buried insulation pipe in urban central heating. High temperature prefabricated directly buried insulation pipe not only has the technical and practical performance of traditional trench and overhead pipeline laying, but also has social and economic benefits. It is also a powerful measure of heating and energy saving.
You can rest assured to buy Pengfa Insulated Spiral Steel Pipe from our factory. The high standards we have established since our inception and maintained to date have earned us a solid reputation and helped us to attract a large number of new customers and talents. Insulated spiral steel pipes are a type of pipeline used for conveying fluids, such as oil, gas, or water. They are made up of a steel pipe wrapped in insulation, which helps to keep the temperature of the fluid constant during transportation.
You can rest assured to buy Pengfa Spiral Welded Pipe Pile from our factory and we will offer you the best after-sale service and timely delivery. In the manufacturing process of spiral steel pipe, there are two ways: longitudinal welding and circumferential welding, among which circumferential welding is the most critical step. Circumferential welding requires the use of an automated welding system that points the welding torch toward the outer surface of the steel plate, making the welding more beautiful. At the same time, parameters such as welding speed, welding current and voltage should be controlled for circumferential welding to ensure that environmental factors such as temperature and humidity in the welding process match the welding process.
You can rest assured to buy Pengfa SSAW Spiral Welded Steel Pipe from our factory and we will offer you the best after-sale service and timely delivery. The production of spiral steel pipe requires steel plate crimping. The traditional steel plate crimping is crimped back and forth between two plate rollers. The surface of the steel pipe produced in this way is uneven, and there are great quality problems. In order to solve this problem, the production of steel pipe usually uses three - roll curved bending machine to roll steel plate. This machine has the advantages of fast coil speed, small bending radius and high quality of finished products, which greatly improves the manufacturing efficiency of spiral steel pipe.
