Description of Seamless Steel Pipe
AISI/SAE 4330VMOD
Seamless steel pipe is a hollow section, no seams of strip steel. Is made from solid tube ingot or the perforation capillary, then through hot rolling and cold rolling or cold dial. Steel pipe has a hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines.

- Q: Are FRP pipes still developing?
- Glass steel complex (or perhaps not, but not absolutely continuous production mishap) manufacturing process, and China quality is not strictly controlled, low cost of pipeline as well as PVC and other engineering plastics, the high demand of the field of steel as reliable, is now used for chemical terminal treatment, city drainage etc..
- Q: What's the process of continuous winding glass fiber reinforced plastic sand pipe?
- On line inspection: the pipe being cut and grinded is delivered to the water pressure test machine through the conveyor. After the test is qualified, the pipe joint which has been tested by hydraulic pressure is sent to the pipe joint installation machine for joint installation.
- Q: How is the glass reinforced septic tank and the cement drain pipe connected?
- Very simple, ah, first install the septic tank, and then drain the pipe ah!
- Q: What is the structure and function of glass fiber reinforced plastic lining?
- The role of FRP lining, corrosion protection, generally attached to the carbon steel container wall, can avoid the use of stainless steel, saving costs. FRP can resist acid and alkali corrosion, PH2-12 or so no problem, but not high temperature, the temperature is higher than 80 degrees, more dangerous, will dissolve.
- Q: The role of glass fiber reinforced plastic cooling towers
- Thermal power plants usually have cooling towers. Water heating, high pressure gas generated by promoting the steam turbine power generation, and the remaining gas cooling.
- Q: What's the price of fiberglass reinforced sand pipes?
- Specifications: DN100--DN4000 are available.Thickness: 5mm--20mm, bothQ:28O5--9I343I/ I86+O38I+2OO7
- Q: How to prevent the glass fiber reinforced plastic pipe from being damaged by aging or over pressure, causing the liquid to splash and hurt people
- When you are in the production design, you should have adequate requirements for the service life, pressure, stiffness, so that there will be no aging and overpressure problems
- Q: How to improve the compressive strength of waste glass fiber reinforced plastic profiles (such as square tubes) should be started with resin, curing agent, glass fiber or other aspects!
- Use a high strength resin type;
- Q: What is the compressive strength of all kinds of FRP materials?
- Heat resistance, frost resistance: at -30 DEG C, still has good toughness and high strength, can be used for a long time in the range of -50 DEG C 80 DEG C, the temperature of resin with special formula can be more than 110 DEG C. 4) of light weight, high strength, convenient transportation and installation by fiberglassreinforcedplastic pipe winding fiber production, the proportion of 1.65 - 2, 1 / 4 only of steel, but the glass steel hoop tensile strength is 180 300MPa, the axial tensile strength of 60 150MPa, similar to alloy steel. Therefore, its specific strength (strength / density) is 2-3 times that of alloy steel, so that it can be designed according to different requirements of users to meet all kinds of internal and external pressure requirements of the pipeline. For the same diameter of single FRP tube, only carbon steel (steel plate) 1 / 2.5, 1 / 3.5 of the cast iron pipe, about 1 / 8 of prestressed reinforced concrete pipe, so the transportation is very convenient for installation. The GRP pipe is 12 meters per length, and can be reduced by 2/3 from the concrete pipe. The socket connection mode of the utility model has the advantages of quick and simple installation, low hoisting cost and improved installation speed. 5) small friction resistance, high transport capacity: glass tube wall is very smooth, roughness and friction resistance is very small. The roughness coefficient is 0.0084, while the n value of concrete pipe is 0.014, and the cast iron pipe is 0.013. Therefore, glass fiber reinforced plastic pipe can significantly reduce the loss of fluid pressure along the course and improve the conveying capacity.
- Q: What is the elastic modulus of glass fiber reinforced plastic?
- Glass fiber reinforced plastic is another name for glass fiber reinforced plastics, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastic. Depending on the fiber used, glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastic (CFRP), boron fiber reinforced composite plastics and so on are classified. It is a kind of composite material made of glass fiber and its products (glass cloth, band, felt, yarn, etc.) as reinforcing material and synthetic resin as base material. Fiber reinforced composites are composed of reinforced fibers and matrix. Fiber (or whisker) diameter is very small, generally below 10 mu m, less defects and smaller, fracture strain of about 30/1000, is brittle material, easy to damage, fracture and corrosion. The matrix is much lower in strength and modulus than fiber, but it can withstand large strains, often with viscoelasticity and elasticity, and is a ductile material.
