FRP flanges, based on phenolic FRP materials at high temperature molding, and its products are standard fiberglass flange DN15-DN800, a variety of fiberglass Blind, flange covers, fiberglass container cover, manhole covers and other non-standard products. The product is high mechanical strength, to acid, corrosion resistance, high temperature (180 ℃) is widely used in chemical, power, pharmaceuticals, pesticides, dyes, smelting, sewage treatment, power plant flue gas desulfurization project and other industries. Brief Description: production of a variety series of glass steel flanges, glass, steel elbows, fiberglass tee, FRP Stone, glass, steel adjustable pipe (FRP size of the head) and other glass pipe fittings products or fiberglass composite pipe corresponding FRP composite pipe Details: 1 implementation of standard glass steel flanges production, inspection and acceptance in accordance with HG / T21633-1991 "glass pipe and fittings" standard. Standard flange dimensions according HG20592-1997, HG20615-1997, HGJ44-1991, HG5010-1958, ASME B16.5-1996, ANSI B16.5-1988 standard, or according to user requirements and design production. 2. Prepare raw materials for examination under working conditions to determine the specifications of the raw materials, models, raw materials into the plant later and inspection report. 3, flange mold process - finishing - made lining - Strengthening - Stripping - Inspection - storage 4, according to the design specifications of prefabricated pipe, flange connection standard mold preparation and cleanup of the mold surface and Dust is completed, brushing release agent. 5, the system lining the prepared gel coat resin brushing the mold, to be gelling laying carpet surface and chopped strand mat, full roll should be no bubbles cracks. 6, to be lining strengthening low pressure contact after curing molding process, E-chopped fiber or glass cloth laid, each layer applied pressure roller full rolling, to meet the design dimensions. 7, the same release liner. 8, testing, storage
