| 产品规格 | Coupling joints, because of their greater flexibility and economy, are steadily replacing flanged pipe joints in today’s plant and marine applications. Unlike flanged joints, couplings not only eliminate the need for costly welding but also compensate for extreme degrees of pipe linear expansion, vibration, and laying deflection. From chemical plants to mammoth tankers, these couplings are utilized extensively throughout plant and marine piping. As a wide range of models is available, the mos |
