16MnR Thick Wall Expansion Joint
16MnR thick-wall expansion joints are commonly used in the pumps, tanks, compressors, turbines at the outlet of container, in order to reduce the force of the above equipment.The bellows are typically fabricated from A516 Grade 70 material, with the thickness ranging from 3/16" to 1". Other materials are available to meet different temperature requirements.Thick Wall Expansion Joint may be a cost-effective option for large-diameter piping systems which operate at low pressure. Metals can be selected to satisfy different temperature conditions.
