3 PE anticorrosive pipe
The 3PE epoxy powder composite steel pipe (also known as TPEP anti-corrosion pipe) is an upgrade product on the basis of the epoxy composite steel pipe in the outer polyethylene, which is the most advanced anti-corrosion form of buried long distance pipeline at present. The self-developed fourth-generation large-diameter pipeline's new anti-corrosion outer wall adopts thermal fusion and winding process to form a three-layer structure anti-corrosion layer with the bottom epoxy resin, the middle adhesive and the outer polyethylene. The inner wall adopts thermal spraying epoxy powder for anti-corrosion, and the powder is evenly coated on the surface of the pipe body after being heated and melted at high temperature. At the same time, it has high strength of epoxy, low water absorption of PE and good softness of hot melt adhesive, with high anti-corrosion reliability.
1 at the end of glue. Before extruding the polyethylene coating, a sealing rubber layer should be applied to the pipe surface. The performance index of base gum is based on the hot melt adhesive of asphalt type used before. National standards on the base of the softening point, heating loss, needle penetration, thermal decomposition temperature, self-repair, shear strength, peel strength, and so on. However, it is proved that the adhesive still has many disadvantages, such as low temperature resistance and poor bonding performance. Some foreign people use butyl glue and the latest resin glue, and domestic base glue is one of the key research topics.
2 polyethylene. The density of polyethylene can range from 0, 91 to 0, 96g /c. The performance is different because of the different densities. Since there is no short bifurcation in high density polyethylene, its junction bii, degree, secondary strength, fracture rate, tear strength, drug resistance is much better than low density polyethylene, which can produce corrosion coatings with different properties and different prices according to the needs of users. High density polyethylene coated pipe (Huang Jiake) the applicable temperature below so ℃, bottom density polyethylene coated pipe (green jacket) the applicable temperature below 60 ℃.
3. Production method. Polyethylene anticorrosive coating used flow dipping process and powder dispersing and melting process, etc. Recently, the production method is basically extrusion method. Bibian of small diameter (15-800mm) is the adhesive circular mould method (with protective layer), and bibian of human diameter (400-1600mm) is the tight t-mould method (no protective layer, single layer). Recently, the use of close - fitting method on small and medium diameter pipe is increasing gradually. In the future, this method may be widely used on anti-corrosion steel pipe

- Q: What are the different methods of pipe lining for steel pipes?
- Some of the different methods of pipe lining for steel pipes include slip lining, cured-in-place pipe lining (CIPP), pipe bursting, and sliplining. Slip lining involves inserting a smaller diameter pipe into the existing steel pipe, while CIPP involves inserting a resin-impregnated liner into the pipe and curing it in place. Pipe bursting involves breaking the existing steel pipe and replacing it with a new pipe, while sliplining involves inserting a new pipe into the existing steel pipe without breaking it.
- Q: What is the impact of steel pipe size on flow rate and pressure?
- The steel pipe size has a significant impact on both the flow rate and pressure. A larger pipe size allows for higher flow rates by reducing the frictional losses, resulting in increased fluid velocity. This leads to higher pressure drops across the pipe due to the increased surface area exposed to the flowing fluid. Conversely, a smaller pipe size restricts the flow, causing higher pressure drops and lower flow rates. Therefore, selecting an appropriate pipe size is crucial to ensure optimal flow rates and pressure levels in a system.
- Q: How are steel pipes used in the aerospace industry?

- Q: How do you calculate the pipe flow rate for steel pipes?
- To calculate the pipe flow rate for steel pipes, you will need to consider various factors. Firstly, determine the inside diameter of the pipe, typically denoted as D. Next, measure the length of the pipe, denoted as L. Additionally, you will need to know the pressure drop, ΔP, across the pipe and the fluid density, ρ. Once you have this information, you can use the Darcy-Weisbach equation or the Hazen-Williams equation to calculate the flow rate. The Darcy-Weisbach equation is commonly used for pipes with turbulent flow, while the Hazen-Williams equation is often used for pipes with laminar flow. For the Darcy-Weisbach equation, the formula is: Q = (π/4) * D^2 * √(2ΔP/ρ) Where Q is the flow rate in cubic meters per second, D is the inside diameter of the pipe in meters, ΔP is the pressure drop across the pipe in pascals, and ρ is the fluid density in kilograms per cubic meter. For the Hazen-Williams equation, the formula is: Q = C * (D^2.63) * (ΔP^0.54) * (L^0.63) Where Q is the flow rate in cubic meters per second, D is the inside diameter of the pipe in meters, ΔP is the pressure drop across the pipe in pascals, L is the length of the pipe in meters, and C is the Hazen-Williams coefficient which depends on the roughness of the pipe. To accurately calculate the pipe flow rate, it is important to ensure that the units of measurement are consistent throughout the calculation. Additionally, it is crucial to have accurate measurements of the inside diameter, length, pressure drop, and fluid density to obtain reliable results.
