Model MPTR Metal Bellows Expansion Joint Pump Connector
Metal bellows Expansion Joint/Pump Connector. The Bellow Pump Connector, which is kept stocked to 14″ for fast delivery, is designed to meet a broad set of needs. It has a 2-ply construction and tie rods that allow it to work well, and economically, in many situations. 150°F Maximum Working Pressure225 psi. 212°F Maximum Working Pressure
Steam distribution - Pipe expansion and supports in steam
Pipe expansion and support. Any steam system must be fully supported, able to expand during operation and sufficiently flexible to allow movement as a result. The expansion device at point 'C' is to accommodate the expansion and contraction of the pipe. in the event of anchor failure, they behave as tie rods and contain the pressure
Custom Metal Bellows & Expansion Joints Triad Bellows
Expansion joints mitigate potential pipe damage due to extreme temperature, vibration, and movement. Two materials—rubber and metal—constitute many existing expansion joints, and each has respective advantages. To learn more about their differences and uses, read our guide to rubber bellows vs. metal bellows expansion joints.
What is the Need of Expansion Joints and Bellows in Piping
Apr 13, 2016 · Universal Expansion JointsThese joints generally have two bellows linked with a center pipe and fitted with the tie rods. They are mainly required to absorb any of the three general movements
Like circular pipe expansion joints, rectangular pipe expansion joints absorb three types of movementaxial, lateral and angular. For the purpose of designing rectangular bellows, it is critical to know in which direction the lateral and angular movements will occur, i.e. parallel to the long and/or short side of the bellows.
Hunter Expansion Joints, LLC applies 40+ years of experience in the design and manufacture of Expansion Joints to deliver cost saving solutions for a diverse spectrum of industries, applications and process equipment. Our broad expansion joint knowledge provides customersThe Lowest Installed Costs; The Highest Quality
Sep 03, 2015 · TIED UNIVERSAL EXPANSION JOINT contain two bellows separated by a pipe spool and tie rods designed to contain the pressure thrust force. These expansion joints are generally designed to accommodate lateral movement only. A universal expansion joint can be designed to have a very low lateral spring force to minimize forces on adjacent equipment
In-Line Pressure Balanced Expansion Joints with Pipe Ends By proper cross linking the change in the volume of the line or flow bellows due to change in the length ( i.e. due to compression or extension) can be made to cause an equal but opposite change in the volume of the balancing bellows.
Aug 20, 1974 · An expansion joint for pipe systems, such as steam pipe systems, including a leak-proof, pressure resistant, flexible bellows joined to the opposed spaced ends of adjacent substantially co-axial pipes, a tie-rod connected to the ends of the adjacent pipes by means of fixing plates affixed to recesses in the ends of the pipes, said tie rod extending substantially parallel to the axes of the
Flange connection general stainless steel metal bellow
Other type of metal expansion joint. Except the flange connection general stainless steel metal bellow expansion joint, there are also other types of metal expansion joint, such as general bellow expansion joint with tie rods, general bellow expansion joint without tie rods, no welding bellows expansion joint, out pressure metal bellows expansion joint, PTFE bellow expansion joint, universal
Metal Bellows Formed Hunter Expansion Joints - Fabric
Metal Bellows “Formed“ style Expansion Joints are often a very cost effective alternative for piping or ductwork systems that carry fluid, steam or other harsh gases or chemicals. Compared to Fabric or Metal Fabricated joints they are often used where pressures are much higher From 5 psig to 300 psig. There are 5 basic designs available:
Expansion Joints - an overview ScienceDirect Topics
Tie rods often used on expansion joints to absorb the thrust are only effective and harmless when the joint is used in shear. If tie rods are used on a joint which is meant to move in tensioncompression, they bypass the joint and make it virtually useless, because pipe forces are then transmitted through the rods.
Jis Expansion Joint, Jis Expansion Joint Suppliers and
offers 12,515 jis expansion joint products. About 95% of these are pipe fittings, 1% are metal building materials. A wide variety of jis expansion joint options are available to you, such as stainless steel, steel, and carbon steel.
Metallic Expansion Joints - Unisource Manufacturing Inc.
Accessories such as tie rods, limit rods, flow liners, and covers can be added, depending on the application. Free-flexing expansion joints are used to control axial pipe movements that typically arise due to thermal expansion. Limited lateral offset, angular rotation, and
Expansion joints absorb this movement and mitigate the risk of must be anchored with standard pipe anchors. Dual expansion joints can also be used where large movement in any combination (i.e. axial, lateral, and angular rotation) is required which Tie-rods are used
Types of pipe expansion joints / expansion bellows
Introduction to Expansion Bellows. In a piping system a Expansion joints alternately known as Bellows are like sealed springs. Sealed because it is required to contain the fluid pressure which is flowing through it and spring because it is required to respond to the movement of the connected piping without offering appreciable stiffness to the piping system.
For tied expansion joints it is not allowed to install them as axial bellows to absorb axial movement. In the piping systems, such as “L”, “Z” and “U” bends they accept lateral or angular movement. Expansion joints are equipped with restraints such as tie rods, hinges and gimbals.
