Product Introduction

Slip on plate flange refers to a kind of flange connected with the pipe by fillet weld. Slip on plate flange is an arbitrary flange. Compared with the neck butt welding flange, slip on plate flange has simple structure and less material, but its rigidity and sealing are not as good as the neck butt welding flange. Slip on plate flange is widely used in the connection of medium and low pressure vessels and pipes. Because the price of the slip on plate flange is large in the pressure pipeline, but its rigidity is poor, it should not be used in high-pressure pipeline, flammable and explosive pipeline and chemical process pipeline with high vacuum requirements. Slip on plate flange commonly used at home and abroad: Ministry of Chemical Industry standards: HG/T20592-2009, HG/T20615-2009; American standard: ASME B16.5, ASME B16.47; National standards: GB/T9124.1-2019, GB/T9124.2-2019.

Standard for slip on plate flange

Flange is a kind of equipment connecting element that can realize the connection and assembly of pipelines and components between equipment. It is widely used in gas, petrochemical, pharmaceutical, metallurgy, paper, energy, condensation, water treatment and other industrial working conditions. At present, thermal cutting flange is the most common flange form in the market, and it is also one of the most mainstream methods used in various connection processing methods As the example of thermal cutting flange processing has greater guarantee on the accuracy and prohibition of the equipment, this paper mainly focuses on the flange made of steel plate, which can be divided into two parts: flat welding flange and extrusion flange. The flat welding flange is formed on the basis of cutting and trimming the edges, and the steel plates at the edges are tightly combined by welding to form a whole structure. The main steps of flat welding flange processing are as follows: (1) Select the appropriate steel plate: when changing the tolerance size, please carefully consider the size of the selected steel plate (2) Cutting and shearing: use steel plate cutting machine and polishing machine to cut steel plate to achieve dimensional accuracy and proportionality requirements. (3) Steel plate welding: adopt linear arc welding, fasten the edge of the steel plate with a small clamp, and add a vertical weld at the weld. (4) Assembly and adjustment: install and adjust various bolts to ensure the symmetry and direction of size and thread are consistent. (5) Inspection: Vernier calipers are used to measure the flange thickness, outer diameter and weld width. Vernier calipers are used to measure the flange size. (6) Polishing: polishing the edge voids to improve the appearance image. All the above processing services for flat welding flanges made of steel plates will be processed according to the requirements of industry standards to ensure that each product and the printing on the steel plate meet the technical requirements. At the same time, ensure that the requirements of safety factor, appearance and durability of the product can be met.
