What is MJ fitting?

The standard defines “mechanical joint” as: “a joint in which a positive seal is achieved when a gasket is compressed by means of a mechanical device.” A mechanical-joint (MJ) connection is the most common method used to join PVC pipe to a valve or an iron fitting.

What is MJ coupling?

The Mechanical Joint (MJ) Coupled Joint offers a method of providing joint restraint with a standard mechanical joint socket of a pipe, fitting, valve or other product.

What lengths are MJ pipe available?

Mechanical Joint Fittings are available in 30” through 48” sizes.

What is AWWA C111?

AWWA C111/A21. 11-17 Rubber-Gasket Joints for Ductile-Iron Pressure Pipe and Fittings.

What is MJ in plumbing?

MJ stands for Mechanical Joint. It is a type of compression joint designed for underground connection for pipe, valves and fittings.

What is mj pipe used for?

Mechanical Joint Pipe (MJ) is primarily used in fittings and valves. The mechanical joint may be configured as a non-restrained or retrained joint using a wedge action retained gland. These joints use the gland’s compression against the bell to wedge the gasket, forming a watertight seal.

What is an MJ gland?

The mechanical joint gland, which is made of ductile iron, is used to press the mechanical joint gasket into the bell. Then bolts or studs are threaded through the gland, squeezing the gasket into place. MJ glands can be specified when purchasing mechanical joint pipe, or they may be available as part of an MJ kit.

What is a Megalug used for?

The Series 1100 MEGALUG® Mechanical Joint Restraints effectively and economically restrain Ductile Iron Pipe (DIP) to mechanical joints above or below ground, for practically any application including valves, hydrants, and pipe.

What is a retainer gland?

Joint Restraint Products. Heavy Duty Retainer Glands provide reliable restraint for ductile iron and steel pipe, valves and fittings. This simple design has been in service for over 30 years. Retainer glands install in minutes, in any type of soil condition and offer guaranteed restraint.

What is AWWA C153?

Back to AWWA C153-11 Ductile-Iron Compact Fittings. This standard describes 3-in. through 64-in. (80-mm through 1,600-mm) ductile-iron compact fittings to be used with ductile-iron pipe or pipe made of other materials with similar outside diameters for conveying potable water, wastewater and reclaimed water.

What is a Megalug fitting?

What is Victaulic coupling?

The Victaulic coupling was used by Allied forces to accelerate the distribution of fuel and water to the troops. The coupling was invaluable for the troops because it decreased the difficulty of assembling and de-assembling pipe lines and allowed them to hasten distribution.

What are Megalugs used for?

How do you join ductile iron pipe?

Push On Joints The most popular, quickest, and easiest-to-assemble joint for Ductile Iron Pipe and fittings in underground applications is the push-on joint. This joint consists of a single rubber gasket placed in a groove inside the socket at the bell end of the pipe.

What is restrained pipe?

Restrained pipe section Piping in which soil or supports prevent axial displacement or flexure at bends is “restrained.” Restrained piping may include the following: Straight sections of buried piping. The straight sections restrained between two virtual anchors. Axial displacements of the pipe are zero.

What is the difference between AWWA C110 and C153?

Description: Today, standard compact fittings C153 are commonly used in place of full Body fittings C110. They are designed to be to be more lightweight and more economical to use while providing better flow characteristics.

What is Tyton joint?

TYTON JOINT® is U.S. Pipe’s trademark product for ductile iron pipe with a push-on type connection. Simplicity, sturdiness and water-tightness are built into the system by design. Convincing proof of its worldwide acceptance is shown by the fact that more than 95% of the pipe now sold by U.S. Pipe is TYTON JOINT Pipe.
