What is a swivel joints ?
Introducing the basic structure and lineup that allows for movement in the front-back, left-right, and up-down directions for fixed piping, while absorbing twists and stresses in hoses!
A "swivel joint" is a piping fitting that allows for 360-degree rotation without leakage while transporting fluids. It is used to provide movement to piping or installed at the base of hoses to improve the efficiency of fluid transport and prevent twisting or damage to hoses. The basic structure consists of a swing piece (rotating side) and a coupling piece (fixed side), and the rotation is achieved with two rows of ball bearings. To prevent fluid leakage, it incorporates a seal packing for internal pressure and a dust seal for external pressure. Connection methods are selected according to the piping connection, including threaded (RC), flanged (JIS, ANSI, etc.), and welded (BE, BO). 【Features】 ■ Reliable quality based on long-standing manufacturing and sales experience since 1955 ■ A product lineup capable of handling low to ultra-high pressure ■ Selection of sealing materials that can accommodate a wide variety of fluids from low to high temperatures ■ Capable of manufacturing from small diameters to large diameters up to 20B (500A) ■ Piping design according to displacement is also possible ■ Extensive experience with submerged specifications for fuel immersed in storage tanks *For more details, please download the PDF or feel free to contact us.
basic information
【Other Features】 ■ Demonstrates stable sealing performance from low to high pressure with a dedicated special packing. ■ The outer ring prevents deformation of the seal and is designed to be resistant to play. ■ There is little possibility of sealing material flowing into the rotating parts, making it difficult for the swivel joint to seize. ■ The trapezoidal cross-section of the packing prevents twisting like that of an O-ring. ■ Sealing materials suitable for fluids and temperatures (NBR, FPM, Teflon, etc.) are selected. ■ Grease suitable for the application (high temperature, food-grade, high pressure) is used. *For more details, please download the PDF or feel free to contact us.
