Flanges are the most widely used detachable connecting parts in pipes and containers. FYGRP flanges are manufactured using excellent quality material and leading technology in conformity with the concert of market norms. To assure their flawless range, our offered fittings are tested under the direction of quality controllers.
Classification by structure
1) integral flanges
2) bonded flanges
3) looper flanges.
Feature
FRP flanges are commonly used in medium and low pressure pipes and vessels with a pressure of not more than 3 MPa.
1) Higher conveying ability
2) Excellent thermal insulation
3) Seamless construction
Advantages
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. Using the vacuum introduction process can significantly improve the strength and pressure quality of the product, overcoming the shortcomings of the past manual flanges.
Manufacturing process
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.
