Product description
       Flange, also known as flange piece (also known as connecting piece) is the most commonly used connection method between track and track. When using bracket connection, only one bracket is welded to the ends of the two rails to be connected to each other, and then the two brackets are connected by bolts. (Threaded flanges are not included) Another method of rail connection is to use rail joints. When connecting with track joints, the tapers should be countersinked on both sides of the track after being aligned, and then fixed with set screws and nuts.
       Product features: beautiful appearance, smooth surface, acid and alkali resistance, anti-corrosion, strong texture performance Technical parameters: please refer to the technical white paper of pipe fittings Packing: wooden box shockproof film packaging or other finish: internal and external mirror surface finish Ra≤0.8μmm, inner wall Mechanical polishing and electro-polishing Ra≤0.2μmm, the outer surface is polished or matt.
    Product use: the product is processed with high-end polishing equipment inside and outside to meet the surface precision requirements; this product is widely used in the external processing of stainless steel piping systems in the industrial fields of food, beer, beverages, pharmaceuticals, chemical industries, etc. Sample processing non-standard products.
Fluorine-lined flange
       Fluorine-lined flange: used for industrial acid-proof and corrosion-proof connecting pieces, toxic gas, corrosive gas liquid, etc., working temperature: t≤150 ° C, not suitable for welding, generally screw connection, diameter lined with PO , PTFE, FEP, PFA, acid corrosion resistance of 99%, generally suitable for sulfuric acid, carbonic acid, chlorine, strong corrosive liquids, toxic corrosive gases, etc.
Butt welding flange
       Butt welding flange is a flange that inserts a pipe into the flange inner ring for welding. Flat welding flanges are divided into two types: neck flat welding flanges and plate welding flanges.
Flat welding flange
       The advantages of flat welding flanges are simple manufacturing and low cost, but the welding workload is large, the electrode consumption is large, and it cannot withstand the effects of high temperature, high pressure, repeated bending and temperature fluctuations. It is generally used for PN≤2.5MPa, normal temperature, working Pipeline with temperature t≤0 ℃.
