Description of Seamless Steel Pipe

P22

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.

Features of Seamless Steel Pipe

High strength

High toughness

High hardenability

The cold deformation

Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe?: Sand sandwiched glass fiber reinforced plastic pipes only have more than one sand sandwiched with glass fiber reinforced plastic pipes, and sand layer can be understood to replace glass fiber with quartz sand. The sand pipe with the same thickness is compared with the glass fiber reinforced plastic pipe, but the sand holding pipe is cheap, but the strength is poor; and the glass steel pipe is opposite.

Q:What are the specifications of glass fibre reinforced plastic cable pipes? What are they?: Strong corrosion resistance, insulation, non magnetic, acid, alkali, flame retardant, anti-static. The utility model has the advantages of good elasticity of bending modulus, complete solution of the corrosion of the metal pipe, no distortion and elasticity, and the defects that the plastic tube is easy to aging and the impact resistance is poor. Good water resistance, can be used in damp or water for a long time without deterioration. Due to the specific properties of glass fiber reinforced plastic, the service life of the glass steel pipe is more than 50 years. The construction is convenient, in particular the repair project, the efficiency is particularly prominent, is the power cable communication cable engineering, municipal engineering and road underground cable is the most ideal protective device, the cable bridge across the river, the use of the most suitable and convenient.

Q:What are the differences between inorganic FRP pipes and plexiglass pipes, what are the advantages and disadvantages?: Inorganic glass fiber reinforced plastic wind pipe: magnesium magnesite soil and glass fiber mesh cloth made of advantages: flame retardant shortcomings: large proportion, low strength

Q:FRP duct material plan is how to mention?: Multi plan square, but also according to the combination of site and construction drawings, to see how much

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: If you are afraid of the glass tube will be such a question, the weak links or parts of the local reinforcement, the conditions can, can re pipe liner, to compression, anti ageing effect

Q:Is the installation of FRP pipes required qualification?: Generally speaking, the glass steel pipe manufacturers will be installed for shipyard workers training, but if the shipyard did not ask, the training goal is to allow workers to master the skills to install, but they do not grant workers qualification certificate, but some shipyard will require workers engaged in installation with the installation qualification, so manufacturers will end in training workers to master confirmation the installation skills of workers, awarded the class approved qualification certificate. I don't know. Are you clear about that?.

Q:Do I need CCC certification for ventilated GRP?: The air duct is made of 10MM thick fiberglass pipe, and the design of the air duct is wrong. The FRP pipe is developed for fire control and smoke exhaust.

Q:What is the stiffness of FRP pipe?: Ring stiffness refers to a technical index of FRP pipes subjected to external pressure.

Q:FRP acceptance standard: As the glass pipe between the use of socket type, double "O" type sealing ring connection, so each installation of a pipe, it is necessary to bear in the socket to suppress, in order to detect double "O" type sealing ring sealing effect. The pressure test pump passes directly through the test hole on the top of the pipe. The water pressure of the pipeline working pressure of 1.5 times after the pump stops (during the operation to open the drain valve exhaust), observation of 2min, the pressure drop value does not exceed the test pressure and the nozzle 5%, no leakage, nozzle pressure test is qualified. If the pressure drop is faster, the sealing effect is poor and needs to be reinstalled to ensure the overall pressure test of the FRP piping system is successful.

Q:Slurry circulation glass fiber reinforced plastic pipe: The slurry circulation glass fiber reinforced plastic pipe has good heat resistance and frost resistance. It can be used in the range of 40 to 80 degrees for a long time. If the resin is specially formulated, it can work at temperatures above 110 degrees celsius.
