Description of Seamless Steel Pipe
P91
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: Designed to support FRP pipes, is it m or mm?
- Glass fiber reinforced plastic cable protection tube chemical composition: GRP winding pipe is a kind of glass fiber reinforced plastic product. With the continuous development of glass fiber reinforced plastic molding technology, FRP products have been widely used in various fields. FRP products have the advantages of light quality, high strength, corrosion resistance, long service life, flame retardant, high temperature resistance and various forms of products. Therefore, the industry gradually increase the use of glass fiber reinforced plastic products, which will be reinforced FRP mechanical properties and molding process put forward higher requirements. The forming process of FRP determines its shape, property and application prospect. The mechanical properties of glass fiber reinforced plastics determine whether their products can be widely used in industries with higher mechanical properties. Fiberglass reinforced plastic square tubes can replace some metal pipes used in industrial and civil fields, such as central air conditioning, chemical plants, etc. but glass fiber reinforced plastic square tube products are not common in the market. This is mainly due to the existence of poor strength, easy deformation and other defects.
- 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 kind of material does glass steel ship honeycomb board use?
- The product adopts composite honeycomb structure, prefabricated glass fiber reinforced plastic panel, high strength glass fiber grid cloth and aluminum honeycomb core material, and is compounded by hot pressing. Because of the high strength of the grid cloth, the impact resistance and flexural strength of the composite board are very high.
- Q: FRP acceptance standard
- Perform hydrostatic test. In order to comprehensively check the installation quality of pipes, the pressure test shall be carried out according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipe works, and the allowable seepage water quantity shall be carried out according to the standards of the steel pipe.
- Q: Glass fiber reinforced plastic GRE pipe broken hole how to repair and repair?
- Don't let the powder go. It is autumn, the temperature is low, so to put more than summer curing agent, as to the exact proportion, I just guess should be: curing agent, accelerator, resin; 1:1.5:8 with glass fiber wrapped around the pipe, coated on the glass fiber cloth to make glass steel with good quickly, let the glass steel the glass fiber cloth fully soaked, waiting for the full glass steel after curing, and then repeated several layers. It will be strong.
- Q: What are the standards for FRP pipes?
- 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 relatively fast, it shows the sealing effect is not good, to re install, to ensure that the FRP pipe pressure test system overall success.
- Q: What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe?
- Glass reinforced plastic sand pipe is actually in the production of glass fiber reinforced plastic pipe, in the middle to increase a layer of sand layer, the purpose is to increase the rigidity of the pipeline. The pipeline in the design according to the use of pressure, stiffness and other conditions to determine the need for sand, if the thickness of the pipe can satisfy the pressure requirements and can meet the requirement of stiffness, is generally not the sand.
- 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!
- FRP corrosion resistance, high strength (afraid of tanks), light quality, easy to install, socket or flange interface, the price is more expensive than cement
- Q: The role of glass fiber reinforced plastic cooling towers
- Central air conditioning also has cooling tower function is to play the role of cooling circulation.
- Q: What are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
- Oil and gas pipelines used for twenty years, basically no corrosion phenomenon. As part of a group of coal tar epoxy primer and topcoat are based on epoxy resin and coal tar as the main film-forming material, add a variety of anti rust paint, insulating filler, toughening agent, leveling agent, diluent, anti settling agents and other materials, the B component is modified amine curing agent or curing agent the main material, adding fillers. When the product is sold, the A and B parts are supplied together, and the mixture is mixed in proportion during construction.
