Flanges

Flanges are the most widely used detachable connecting parts in pipes and containers. With the increasing use of FRP pipes and containers, the performance and manufacture of FRP flanges have gained more and more attention.

FRP flanges are commonly used in medium and low pressure pipes and vessels with a pressure of not more than 3 MPa. The main structures are integral flanges, bonded flanges and looper flanges.

FYGRP flange manufacturing method has been applied for international patent, mold integrated molding design, made in vacuum introduction process, deformation is particularly small, different from manual flange products with the shortcomings of surface bubbles, uneven force, high resin content, low strength.

The manufacturing process is: grinding mold, cleaning mold, dewaxing, painting 100% resin soaked surface felt, then according to the design layer to place glass fiber, then vacuum, finally wetting resin, curing into the flange blank, after demoulding for hole repair. Using the vacuum introduction process can significantly improve the strength and pressure quality of the product, overcoming the shortcomings of the past manual flange,meeting the standards of DIN、BS、NF、UNI、ANSI、JIS、GB、ASME、CBM and so on.
