Xinxing Ductile Iron Pipes Joint Types of Ductile Iron Pipes

EDITION 2009

The T-type joint designs

incorporate a single

rubber sealing gasket

assuring a tight,

permanent seal. The

"push-on" type joint is

easy to assemble and fast

to install. The push-on

design eliminates the

need for glands and

fasteners. The rubber

gasket fits inside the

contour of the bell socket,

which seats the gasket.

The plain-end (spigot) of

each pipe is beveled to

further ease assembly.

2. K-type Joint

The mechanical joint is a bolted joint utilizing a ductile iron gland and mechanical

joint gasket. The mechanical joint is recommended for water service where many

connections are required. All components of the mechanical joint are

interchangeable. The spigot end of mechanical joint pipe has the same outside

diameter as push-on joint pipe. As a result, it can be fitted into such joints in the

field by beveling the outside edge. All of the accessories (glands and fasteners)

are supplied with each joint.

3. TF Type Self-anchored Joint

Self-restrained Type is a push-in self anchored joint. The principle of joint

anchoring consists in transmitting the axial forces from one pipeline to the

following one, thus ensuring that the joint does not come apart.

The application of self-restrained joints is of particular interest where congested

conditions preclude concrete anchor block constructions or in poorly cohesive

soils.

Self-restrained joints combine the advantages of flexible joint pipes and welded

joint pipes.

Self-anchored joints allow the axial thrusts arising at particular points (bends,

tapers, tees, blank flanges) to be distributed over one or more pipes, thus

avoiding installation of concrete anchor blocks.

The seal is provided by a standard gasket.

The axial force transmission is through a mechanical arrangement, independent

of that providing the seal, comprising:

1. Weld been on the pipe spigot

2. A one-piece or segmented anchoring locking ring with a curved external

profile, which abuts against the weld bean

3. A special gland, which blocks the locking ring.

4. Iron bolts.

2. External positive pressure: 2.0 bar

PFA: maximum internal pressure, excluding surge, which a component can safely withstand in permanent service

PMA: maximum internal pressure, including surge, which a component can safely withstand in service

PEA: maximum hydrostatic pressure that a newly installed component can withstand for a relatively short duration, when

either fixed above ground level or laid and backfilled underground, in order to measure the integrity and tightness of

the pipeline

NOTE: This test pressure is different from the system test pressure, which is related to the design pressure of the pipeline.
