FRP elbow used for glass steel of low and medium pressure pipeline system, high glass steel elbow mechanical strength, excellent hydraulic performance, resistance to chemical corrosion resistance strong, of excellent fire retardant, low thermal conductivity, small expansion coefficient, good heat resistance, light weight, excellent aging resistance, the long service life, convenient installation, design, widely used infood, chemical, power, pharmaceutical, pesticide,dye, iron and steel, metallurgy, water treatment, tap water, seawater, desulphurization and environmental protection field.

 

Forming process of glass fiber reinforced plastic bend

FRP elbow by hand lay up molding, solid peptide FRP hand lay up molding FRP elbow have three kinds of structure form, respectively mould is shaped integrally, mold half divided body molding, piping prefabrication shrimp bend forming.

1, the mold on the whole forming, using the solid peptide glass fiber reinforced plastic has the following DN800 metal or glass steel mold, in which the use of glass fiber reinforced plastic raw materials by hand lay the process of forming.

2, half of the mold split forming, in the solid peptide glass fiber reinforced plastic without the relevant elbow under the premise of the production of half elbow mold, the production of 2.5 glass steel elbow, the two together into a bend finished.

3, piping prefabrication shrimp bend forming, first produced corresponding specifications of the FRP pipe, and pipe cutting into several segments spliced into a bent. This molding method mostly used has a certain stiffness requirements, or there is no ready-made molds of glass steel elbow in and making mold costs are relatively high premise.
