Can fiberglass-reinforced plastic pipes have a diameter of less than 50 mm?
Thread Content
I found some standards for fiberglass-reinforced plastic pipes, and the pipe diameters (nominal diameters) specified in those standards are all above 50 mm. I wonder whether it is possible to manufacture fiberglass-reinforced plastic pipes with a diameter of less than 50 mm? What is the wall thickness at a pressure of 1.0 MPa?
It’s possible to do it; our company’s minimum diameter is 15 mm, with a thickness of around 5 mm
It’s possible to do this, as long as the appropriate molds are available. For pipes with a diameter of DN50 or less, a thickness of 5 mm is not actually necessary to meet the 1.0 Mpa requirement; however, for easier demolding, 5 mm is generally used
I agree with what was said on the 3rd floor. When designing fiberglass-reinforced plastic pipes, it is necessary to meet not only the requirements related to the use of the pipes but also those related to the manufacturing process. For pipes with a diameter of less than DN50, the pressure rating is 1.0 MPa and the wall thickness is 5 mm; this takes into account the requirements of the manufacturing process. If the molds are of high quality, it is possible to produce pipes with a thickness lower than this value as well.
It’s possible; our company has used it before.
The molds for fiberglass reinforced plastic pipes are now quite well-developed, and the pipe dimensions can be exactly the same as those of steel pipes.
It’s completely possible; DN25, DN32, DN15 are all feasible. The pressure rating can be lower, such as PN2.5, etc.
Sure. The equipment I bought comes with glass fiber pipes smaller than DN50. This post was last edited by cjzhou2 on 2009-4-19 00:19.]
It is possible to achieve less than 50 mm; the wall thickness is determined based on pressure requirements
Of course it’s possible; the smallest ones available now can reach one inch
