Description of Seamless Steel Pipe

Straight seam submerged arc welding steel 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:What are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
Epoxy coal tar coating consists of two main components with epoxy coal asphalt composition, is a (epoxy) B (curing agent) two-component coating, with good adhesion, toughness, moisture resistance, water resistance, chemical resistance, has the properties of prevent various ions through the film, and is coated with objects with the expansion of shrinkage characteristics. The paint film never falls off or cracks.
Q:Is it possible to touch the water when the glass fiber reinforced plastic pipe is polished?
Because the resin curing mechanism of FRP products is resin, resin agent, resin curing agent together to react, and release a lot of heat, this process does not affect the curing process because of a small amount of water and at the same time, if you have a little bit of water molecules would because of the large amount of heat emitted by evaporate, so does not affect the bonding of glass and steel that will not affect the glass steel pipe interface
Q:A basic overview of FRP pipes
FRP pipes are made of resin (feed water, food grade resin), glass fiber and quartz sand as raw materials and made by special process.
Q:What are the functions of glass fiber reinforced plastics?
Glass fiber reinforced plastic (FRP) is a kind of composite material which has been developing rapidly for more than fifty years. 70% of glass fiber output is used to make fiberglass. Glass steel is much harder and much lighter than steel.
Q:What can be done to solve the leakage of FRP pipe?
DN1800 FRP pipe pressure of 9 kilograms, the pressure is very high, crushed by stones, not repaired will certainly leak, the pressure pipe leakage is very bad, will be washed away the soil, spewing a few meters high water column.
Q:The difference between GRP cable duct and PVC cable pipe
PVC cable pipe refers to various kinds of rigid PVC pipes made of PVC resin as main raw material and various stabilizers.
Q:Is there any ventilation duct made of glass fibre reinforced plastic in Baotou?
Fiberglass pipeacid and organic glass steel fan shell with acid and alkali corrosion resistance, long service life, is mainly used in chemical, textile, printing, metallurgy, underground facilities for discharging corrosive gas places.
Q:Would like to ask about the plastic lined steel pipe, steel pipe, glass steel skeleton, the advantages and disadvantages of each ceramic pipe, to know a friend told, very grateful!
Steel skeleton pipe is not corrosion resistant, often used in drainage, easy to install, the price is almost the same as fiberglass, cheap inside there is no steel skeleton
Q:Glass fiber reinforced plastic pipe to withstand 1.0MPa pressure, pipe wall to do how much thickness?
Glass tube wall thickness is generally determined by the manufacturer design, with stereotypes products and sequences, you can choose according to the pressure level.
Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
It is a resin based glass fiber weight layer wound on the mandrel rotating on according to process requirements, and distance evenly between the fibers as Kamiishi Eisa in the sand layer.
