Requirements and test methods. These locking gasket systems allow the pipe to be pushed together but do not allow the joint to come apart without using a special tool or torch on the gasket. Due to the rigid nature of the joint and the risk of excessive bending stanard being imposed, it is advised that flanged pipework is not buried.

Manufacturer of ISO2531 BS EN545 & 598 Standard Ductile Iron Pipes

However, it is the external diameter of the pipe that is kept constant between changes in wall thickness, in order to maintain compatibility in joints and fittings.

It also stanxard performance requirements for couplings, flange adaptors and saddles that are manufactured to use with ductile iron pipes and fittings.

Retrieved 30 January In Europe, standards recommend a more sophisticated system of directly bonded zinc coatings overlaid by a finishing layer be used in conjunction with polyethylene sleeving.


In the European market flanges are usually welded onto the pipe. The latter may or may not be reinforced with a scrim layer.

Corrosion Inspection and Monitoring. Spigot and sockets involve a normal pipe end, the spigot, being inserted into the socket or bell of another pipe or fitting with a seal being made between the two within the socket. Shanxi, China Model Number: We operate in countries and are the number one certification body in the UK and US. This took several weeks to set and produced a completely rigid joint.

Product List Supplier List. In highly corrosive environments loose polyethylene sleeving LPS to encase the pipe may also be used. For potable water, portland cement is used; for sewage it is common to use sulfate resisting or high alumina cement.

Ductile iron pipe – Wikipedia

Life expectancy of unprotected ductile iron pipes depends on the corrosiveness of soil present and tends to be shorter where soil is highly corrosive.

A gasket ring was pushed into the socket round the spigot to contain the mixture which was pounded into the socket with a caulking tool and then pointed off.

Retrieved 8 October Push joints remain proprietary designs. Ductile iron pipes, standarf, accessories and their joints for water applications Report. Ductile Iron Pipe Research Een545.

The most modern is the ‘push-joint’ or ‘slip-joint’, whereby the socket and rubber seal is designed to allow the pipe spigot to be, after lubrication, simply pushed into the socket.

Of these, cement mortar lining is by far the most common. The National Association of Pipe Fabricators. How does it work?


Individual lengths of ductile iron pipe are joined either by flanges, couplings, or some form of spigot and socket arrangement. Journal of Construction Engineering and Management.

Suppliers with verified business licenses. Ductile iron pipe is sized according to a dimensionless term known as the Pipe Size or Nominal Diameter known by its Em545 abbreviation, DN. The cement mortar comprises a mixture of cement and sand to a ratio of between 1: The faster, standare way to work with standards.

This can be to transport different types of water with or without pressure, below or above ground. The predominant form of lining for water applications is cement mortar centrifugally applied during manufacturing.

Retrieved 9 October Mechanical joint K-type is used mostly for pipes with big diameter. This study found improved environmental performance for ductile iron pipe in terms of energy consumed and emissions produced during manufacture due to its longer life span.

Provide installation manual which support the contractor on the proper soil, handling, storage, bedding, laying, joining, backfilling and testing procedures. LPS comprises a loose sleeve of polyethylene that completely wraps the pipe, including the bells of any joints. Sfeir Trading FZC will provide the contractor a site service representative to train on the site preparation, installation and testing.
