Mechanical Joint K Type

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.

Handling and Transportation of Ductile Iron Pipe Mechnical Joint K Type.

Hoisting

Take precaution of handling pipe with steel cable, hoisting belts and specialized rigging avoiding from pipe's rocking. While using steel cable, single cable is not admitted, for the purpose of protecting outer anti-corrosion layer, steel cable should be packed by rubber or other similar material. While using hook, it also should be covered with rubber or other similar material for protecting cement lining layer. Especially for pipe with relative large diameter, hook should be mounted a gasket with same shape as internal diameter of pipes while handling. It is not available fixing hook on the steel belts or socket side and spigot side of pipe while handling pipes in bundle.

Transportation

Put two pieces or more woods on the platform of the vehicle while transporting, pipes are laid on the wood and fixed by wedge. The part over the vehicle body should not be more than 1/4 of overall length of pipe. If pipes are piled up more than one layer, each layer of pipes should reverse, and buffering rubber or gasket should be put on the space between two layers of pipes, at last pipes are fixed up with steel cable and buffering gasket. Check often if pipes can fall out during conveying, and check if stop wedge is not hard up. The vehicle should slow down on the uneven road or while swerving.

Storage

Under pipes there should be put wedge or crosstie while stacking pipes, and socket and spigot of pipes should be interleaved and on the stop wedge in cast of pipe's rolling. Uneven and serious polluted ground, or slope and marshy are not available.
