Description of Seamless Steel Pipe

Spiral seam submerged arc welding pipe

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:Is it useful to make gas pipelines with glass steel pipes? Or the idea that the technology is mature?
I don't think it's enough, because the strength of FRP is not enough, it can easily be brittle and easily perforated in the field for a long time!
Q:Designed to support FRP pipes, is it m or mm?
The glass steel pipe wall smooth, do not scratch the cable, socket type interface, convenient installation and connection to thermal expansion and contraction, the proportion of small, light weight and reduce installation labor, reduce the cost of installation, FRP cable protection pipe used for electric power, communication cable, in various environmental protection pipe laying cables, especially through the traffic crossing to the cable across the river the use of the bridge, under special circumstances, can fully reflect its simple construction, high strength, excellent performance, widely used in electric power, communications, transportation, civil aviation, airport infrastructure and other Domain company always adhere to the "customer first, integrity management, intentions services for business philosophy, is willing to work with friends from all walks of life to strengthen cooperation, mutual cooperation, common progress and win-win
Q:What are FRP pipes made of?
The wall of the pipe is smoothReduce flow resistance, increase flow speed and reduce energy consumption. Compared with the same size steel pipe, the flow rate of the same volume can be increased by about 10%, and no fouling and long-term use can not reduce the flow rate. The protection of cables in interference and heavy corrosion environment is better.
Q:What is the thickness of all types of FRP pipes?
DN200, DN150, DN100, DN80 pipe, polyurethane foam pad, 50mm thick shell, glass steel, thickness 3mm.
Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
The pipe wall structure reasonable and advanced, can give full play to the role of material, to meet the premise of use strength, improve the rigidity, ensure the stability and reliability of the product. Because of its excellent chemical resistance, light weight, high strength, no scaling and strong seismic resistance, the glass steel sand inclusion has the advantages of long service life, low overall cost, quick installation, safety and reliability compared with ordinary steel tubes.
Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
When the length and width of glass fiber mesh are not enough, the method of lap joint must be adopted to improve the tangential bearing capacity of the joint, so as to effectively overcome the radial tensile stress, bending force and bending shear stress. The lap length of the glass fiber cloth at the joint is generally 50 to 100mm, and the joint of each glass fiber cloth should be at a certain distance from the adjacent joint. The longitudinal and transverse joints between adjacent layers shall be greater than 300mm, and the distance from the same seam shall not be less than 500mm.5) paste made of circular duct, glass cloth along the radial 45 degree angle to the direction of cut cloth; conical paste products, according to the fan-shaped cloth.
Q:What kind of material does glass steel ship honeycomb board use?
Analysis of glass steel tube and glass steel tube cellular communication used in communication network construction, is currently used PVC bellows and PVC honeycomb tube, pipe and pipe crossing is the use of plastic pipe or galvanized steel pipe.
Q:Why FRP pipes for outdoor waste gas treatment equipment are selected?
Glass fiber reinforced plastic properties: light and hard, non conductive, stable performance, high mechanical strength, less recycling, corrosion resistance.
Q:What is the heat preservation of the plumbing pipe now? I'd like to use fiberglass Seek help from a master
Glass cotton + glass steel pipe shell: high cost, long construction cycle, good insulation effect.Rock wool insulation: high prices, poor construction conditions, poor heat preservation, water after a mess.Polyurethane foam + yellow jacket: high price, good insulation effect.Galvanized sheet + glass cotton: cheap price, quick construction, good insulation effect.
Q:Characteristics of FRP pipes
The main pipe forming process of FRP is controlled by a computer for agricultural irrigation, as specified on the mandrel and tube glass fiber winding process the same manufacturing gel lining, according to design good linear and winding structure layer thickness, and the quartz sand and resin sand slurry mixed entangled in the structure layer. The outer protective layer. Raw and auxiliary materials: resin, short cut fiber, continuous glass fiber and quartz sand.
