What is a mechanical joint pipe?
Mechanical joint pipe is a time-tested ductile iron product with joint dimensions conforming to the standardized dimensions in AWWA C111. Mechanical joint pipe is UL Listed and FM Approved.
What is expansion joint in mechanical?
Expansion joints provide stress relief from thermal and mechanical vibrations and/or movements in piping systems. For expansion joints to perform properly—compress when the pipe grows—they must be located between two fixed points or anchors. An anchored piece of equipment is considered a fixed point.
How do mechanical joints work?
The mechanical joint seals by the force of the t-bolts pushing the gland, which moves and compresses the gasket. With the gasket being trapped in a confined volume and the gland pushing from one side, the gasket experiences an increase in internal pressure.
What is a flanged fitting?
A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. Although the word ‘flange’ generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as flanges.
What are the different types of mechanical joints?

What is restrained joint pipe?
Restrained joint pipe and fittings are used in pressurized Ductile Iron pipelines to prevent the joints of the line from separating due to thrust forces. Thrust forces generally occur at changes of direction in the line.
What is flange joint?
Is a mechanical joint restrained?
A restrained joint is a special type of push-on or mechanical joint that is designed to provide longitudinal restraint. Restrained joint systems function in a manner similar to thrust blocks, insofar as the reaction of the entire restrained unit of piping with soil balances the thrust force.
What are the types of Mechanical joints?
Mechanical joints are of two types: permanent joints and temporary joints. Permanent joints are those that cannot be undone once made – providing, in general, more stress resistance. Welded joints are made by using high temperature and riveted joints are those which use rivets to fasten two members.
What is mechanical joint connection?
Bolted Joint. A bolted joint is the most common temporary joint used in the design of a system or machine.
What are the types of weld joints?
