Assembly of the joint is quick and simple, and may, according to size and local conditions, be carried out by any of the following methods.

Crowbar method
Complete entry of the spigot into the socket may be obtained by pushing with a crowbar or a suitable lever against the face of the entering Ductile Iron Pipe.

Fork tool method
Maybe used for 100mm and 150mm Ductile Iron Pipe. The fork is placed over and behind the socket of the last Ductile Iron Pipe laid. A wire rope with eye at one end and a hood at the other is connected to the socket of the Ductile Iron Pipe to be jointed as shown in the diagram. The fork is now pulled in direction of arrow and the spigot enters the socket. Reasonable force should only be used.

Trifor or Come along method
For joint above 150mm a wire rope or chain can be used as shown in the diagram.

Trench excavator method
When the trench is being prepared by using a back hoe or excavator, wither machine may also be used to push the spigot home. This system is mainly used on large diameter Ductile Iron Pipe and a timber header should be placed between the Ductile Iron Pipe and the bucket to prevent damage to the Ductile Iron Pipe.

Before assembling the joint, the spigot of the ductile iron pipe and interior of socket of the adjacent ductile iron pipe should both be thoroughly cleaned.

Insertion of gasket

The gasket should be wiped clean, flexed as shown in the diagram, and then placed in the socket with bulb leading. The groove in the gasket must be located on the retaining bead in the socket, and the retaining heel of the gasket firmly bedded in its seat so that the heel of the gasket is not proud of the mouth of the ductile iron pipe. Ensure the gasket fits evenly around the whole circumference of the ductile iron pipe, removing any bulges from the ductile iron pipe that prevents the proper entry of the spigot end.

Lubrication

A thin film of lubricant is applied to the inside surface of the gasket which will be in contact with the entering spigot. In addition, a thin film of lubricant should be applied to the outside surface of the spigot end.

Initial entry of spigot

The spigot of the ductile iron pipe being jointed must be aligned and entered carefully into the adjacent socket until it makes contact with the gasket. Final assembly of the joint is completed from this position.

Completely assembled joint

Joint assembly is completed by forcing the spigot end of the entering ductile iron pipe past the gasket, which is thus compressed, until the first painted strip on the end of the ductile iron pipe disappear and the second painted strip is approximately flushed with the socket face. If joint is difficult to assemble, the spigot should be removed and rotated 90 degree before attempting to assemble a second time. If the joint is still difficult to assemble, the spigot should be removed and the gasket examined.

Deflection

The joints can be deflected in any directions up to 5 degree for ductile iron pipe up to 300mm diameter nominal size, up to 4 degree for 350mm and 400mm size and up to 3 degree for 450mm to 700mm. All spigots must be chamfered. When making a joint, ductile iron pipe should be always be in line and if required, deflection made after jointing.

1st Method of Gutter Installation

1) Mark a center point on the formwork where the UPVC pipe is to pass through the concrete floor slab, then get a nail to punch a small hole on the said point. Put the Gutter Down pipe sleeve on top of the formwork so that the central hole is perpendicular to the hole already marked and fastening the sharp screw onto the formwork.

2) By fastening the sharp screw from the Gutter Down pipe sleeve central hole to the formwork the “Y” portion will naturally bend downward and force the Gutter Down pipe sleeve to clamp against the formwork firmly. This is to ensure correct and stable positioning of the Gutter Down pipe sleeve during concrete casting.

3) When the formwork is removed after the concrete floor is cast, the “Z” and “Y” portion will break off leaving the Gutter Down pipe sleeve cast within the concrete floor slab. Some touch up filling is necessary at “Z” portion before connection UPVC pipe.

2nd Method of Gutter Installation

1) Gutter Down pipe sleeve are provided with four nail hole fastening locations outside the cylindrical body. The Gutter Down pipe sleeve is placed on top of the formwork where the UPVC pipe is to pass through the concrete floor slab. Four nails are then fastened firmly onto the formwork.

2) When the formwork is removed after then concrete floor slab is cast, the nails will be exposed beneath the Gutter Down pipe sleeve. Bend the nails toward the floors slab or cut them away. Additional cement plastering will cover the bend nails.

3) Apply the PVC solvent cement on “X” portions all round for connection of the UPVC pipe into the Gutter Down pipe sleeve.

4) Please ensure that the extension UPVC pipe are fitted (without solvent cement) into the Gutter Down pipe sleeve before the concrete is cast, if the thickness of concrete floor slab exceeds the heights of the Gutter Down pipe sleeve. Remove the extension UPVC pipe from the Gutter Down pipe sleeve after the concrete floor is cast.

5) In order to have a better discharging flow system for the main stack, it is important to align the connecting UPVC pipes centre points to ensure optimum efficiency. Insert an extension UPVC pipe into the Gutter Down pipe sleeve which had already casted in the floor slab below. Then place a laser pointer pen holder onto the UPVC pipe, so that the centre point can be located at the underneath upper floor formwork. Thereafter made a nail hole and then place a Gutter Down pipe sleeve on top of the formwork, and fastening by the sharp screw.

1. Standard Connection method

The most common method in connecting PEX piping to PEX fitting is to use a copper crimp ring and a PEX crimping tool. The fitting is to be inserted into the PEX pipe, the copper crimp ring is to be inserted around the pipe and the copper ring is to be crimped over the pipe. All these components can be easily obtained from a retailers or suppliers locally or internationally.

2. Expansion Fitting method

The expansion method requires the use of an expansion tool to increase or expand the inner diameter of the PEX pipe. Special PEX expansion fitting also required to be inserted into the expanded pipe, which purpose is to shrink back the PEX pipe to shape around the fitting. A plastic ring is required to be pressed over the PEX fitting to ensure a close fit connection.
This method was developed as a proprietary solution, and is currently available from one company. Information about testing standards for this method can be found on the ASTM standards page.

3. Stainless steel clamp method (SSC)

The stainless steel clamp method uses special clamps mainly designed for PEX piping connection. The PEX fittings used here are the same as in the Standard Connection Method, but in this method the stainless steel clamp fastens the PEX pipe to the PEX fitting. A special SSC crimping tool is needed to tighten the clamp around the PEX pipe and PEX fitting.

4. Compression Method

Standard compression fittings can be used to make connections between PEX piping if size of the job is moderate to large size jobs and this PEX piping connecting method is more expensive than using the Standard Connection Method due to the higher cost for compression fittings cost compare to PEX fittings.

5. “Push-fit” and other methods

Some companies offer specialized PEX fittings that will connect PEX to PEX or PEX to copper, PEX to PVC and PEX to other materials as well. This type of PEX fittings use one or more of several common technologies such as stainless steel gripping teeth, EDPM O-ring seals, and threaded compression nuts. These PEX fittings are faster and easier than most other methods, but the cost is higher per fitting than standard PEX fittings.

There are several types of piping such as copper pipe, steel pipe, polyethylene pipe, unplasticised PVC (UPVC) pipe, ductile pipe, cast iron pipe, galvanized pipe, poly pipe, concrete pipe, aluminum pipe, stainless pipe, metal pipe and etc, all of them have their unique installation pipe procedure and method. In this article, that will be a simple video clip that teaches how to lay the water pipe, it’s just a rough installation pipe procedure. The piping contractor is laying 12″ water main line for a new road.

How To Lay Water Pipe

1) Excavation
One excavator and Compaction Wheel have to be used for excavation work. The excavator will be excavating the earth or soil in straight where the water pipe has to be installed.

2) Compaction
After the excavator has excavated the earth or soil, the Compaction Wheel will be compacting the ground to make the soil become solid and stronger.

3) Laying Water Pipe
After the excavation work and compaction work have been done, the piping workers will be laying the water pipe on the excavated ground.

4) Filling
After the water pipes have been properly lay, excavator has to do filling work which is filling the excavated earth on the water pipe. After these, compaction wheel will be compacting the ground again. After all the works have been done, road work will be going on.
