Introduction of Universal Hinge Corrugated Compensator Universal hinge corrugated compensator can absorb displacement in any direction, and also absorb axial displacement X and lateral displacement Y. It should satisfy X < XO, Y < YO. The axial compensation listed in the parameter table is mainly compression displacement, which is used to compensate the angular displacement in any plane of the pipeline. It is generally installed on the horizontal or vertical powder feeding pipe at the entrance of the burner. 。 Specification series DN200 ~ DN600, specifications outside the series, can be ordered separately from the manufacturer. Universal hinge ripple compensator has a universal ring. There are two pairs of vertical hinge structures around the universal ring. Therefore, it can absorb the angular displacement of any plane. When it can absorb displacement regularly, it should be used in two or three combinations. It is mainly used in the pulverized coal feeding pipeline of power plant boilers to absorb the downward thermal expansion of boiler hearth and furnace hearth. Transverse expansion and thermal displacement of powder feeding pipe. Universal hinge corrugated compensator (WJY), also known as universal hinge corrugated expansion joint and universal hinge corrugated expansion joint, is mainly used in power plant boiler powder feeding pipeline to absorb downward thermal expansion of boiler hearth, transverse expansion of furnace hearth and thermal displacement of powder feeding pipeline. Safety precautions for universal hinge corrugated compensator: 1. The small tie rod on the compensator is only used for transportation, installation and "cold tightening". After installation, it must be removed. 2. When the angular deformation of compensator is large or the working pressure of the system is high, the recommended product should be "cold-tightened" during installation, usually 50% cold-tightened or 100% cold-tightened. The advantages of cold tightening are mainly to improve the working stability of expansion joints and pipelines. Performance parameters of universal hinge ripple compensator: 1. Use pressure (p): <0.1 MPa (design blasting pressure <0.35 MPa); 2. Service Temperature (t):.0-350 C 3. Bellows structure: double-layer structure of austenitic stainless steel plate, inner layer 0Cr17Ni14MO2, outer layer 0Cr18Ni9 (GB3280) Model: Our factory produces DN100-DN6000 Pressure level: 0.1 Mpa-2.5 Mpa Connection mode: 1. Flange connection type; 2. Nozzle connection type. Product angular compensation: +4-+9 Over the past few years, our Gongyi Hongsheng Pipeline Equipment Co., Ltd. has continuously developed new products, improved product quality, done a lot of research and experiments, put forward a new product structure, greatly improved the performance of the products, and won the praise of the vast number of users. If special specifications of products are needed, they can be designed and manufactured according to user's requirements. And sincerely hope that new and old customers, design units recommend the use of our company's products.
