Hengshui City Value Optical Engineering Rubber Co., the predecessor of Taocheng scale light Rubber Products Factory, the company specializes in the production of a bridge with a prestressed corrugated plastic pipe, prestressed corrugated metal pipe, ultrasonic test tube (Acoustic Pipe), embedded bolt corrugated tube, pipe, flat tube, rubber ...... specification is complete quality assurance! The company has passed ISO9001: 2000 international quality system certification, the products are widely used in bridges, roads, concrete works! Metal bellows type components using temperature range is very wide, generally in the design and manufacture of elastic element is given before. Some special purpose bellows cavity by oxygen (-196 ℃) or lower the temperature of liquid nitrogen, pressure up to 25MPa. Pipeline system connecting large bellows expansion joints (sometimes more than the nominal diameter lm), requires pressure 4MPa, temperature 400 ℃, and there is a certain degree of corrosion stability. Temperature adaptability elastic element depends on the use of heat resistance of the elastic material. Therefore, according to the elastic element temperature range, the choice of a suitable temperature performance parameters of elastic material can be processed to produce qualified bellows type components. Metal bellows works: Mainly elastic element corrugated compensation for stainless steel bellows, bellows expansion dependent, bending the pipeline axial, lateral, angular compensation. The role of the metal bellows can play: 1. Compensation for absorption pipe axial, lateral, angular thermal deformation. 2. The vibration absorbing devices, equipment to reduce the impact of vibration on the pipeline. 3. absorb earthquake, subsidence of the pipeline deformation. Metal bellows and elastic element in a particular position change (the free end or central) In accordance with its trajectory, can be divided into linear displacement and angular displacement. In the external load, metal bellows may produce axial displacement, angular bit extravagant and lateral displacement.
