Product Description
Type N Style I ball joints have been widely accepted since the design was introduced in 1960. They are commonly used in steam, hot water, chilled water, petroleum and chemical piping to absorb thermal expansion. Common applications are tank and building settlement, seismic isolation, bridge movement and wave motion compensation in addition to steam and hot water distribution systems.
Standard models are available as weld end or flanged with optional seal materials. The total flex angle varies with size from 15º to 31º. Refer to Column 3 of the Dimensional Data below.
Standard materials are wrought steel for the ball, case and retainer. The ball sealing surface is protected with crack free chrome plating and coated with molybdenum disulfide.
Type N Style I Ball Joints
Flex torque is the moment (ft.-lbs.) at break-a-way to angularly displace a ball joint. Because the pressure thrust is reacted by the seals the flex torque is a function of pressure as illustrated by the adjacent charts for Number 11 composition seals. The values for Number 24 glass filled Teflon® seals are 15% less than the Number 11 seal values.
The values given are for steam service. For water or oil service the torque values are 45% less.
Seal Number 11
Compound 11 is a pressure molded proprietary seal compound recommended for general purpose applications for steam, hot water and oil systems. Compound 11 has the highest pressure/temperature ratings of the available seal materials.
Rated for service at temperatures from -50º F to +525º F.
Seal Number 24
Compound 24 is pressure molded proprietary compound of glass fiber and Teflon®. The addition of the glass fiber adds strength and stability to the seal. The compound is chemically inert and is recommended for applications involving corrosive fluids when a higher pressure rating is required.
Rated for service at temperatures from -325º F to +425º F.
Ordering Instructions
