Description
The compensator manufactured by Hebei Hexin Pipe Fitting Co., Ltd. has a nominal diameter of DN65, a nominal pressure of PN16, and is made of A105 carbon steel. This product is generally a metal bellows compensator, which is formed by hydraulic molding or rolling welding of high-quality thin A105 carbon steel plates or stainless steel plates, with flanges or connecting pipes welded at both ends. The production process includes plate blanking, bellows forming, heat treatment (stress relief), welding with end pipes/flanges, assembly, pressure testing, air tightness testing, etc. It is mainly applied to pipeline systems such as heat supply pipe networks, petrochemical industry, flue gas desulfurization, and building heating and ventilation. It absorbs axial, lateral or angular displacements caused by thermal expansion and contraction of pipelines and reduces vibration. Compensators made of A105 carbon steel feature a wide temperature resistance range, generally from -20°C to +400°C (subject to specific design), with a pressure resistance of PN16 (approximately 1.6 MPa), and their pressure-bearing capacity can be improved by increasing layers. Hexin Pipe Fitting boasts advantages including sophisticated bellows forming technology, strict welding process control and comprehensive performance testing. The company provides a wide range of production specifications, with nominal diameters generally ranging from DN32 to DN6000, pressure ratings from PN0.6 to PN40. The compensation capacity can be customized according to requirements. Available structural types include axial type, lateral type, angular type, pressure balanced type, etc. The company also offers materials such as 304/316 stainless steel and heat-resistant steel.
