Dismantling joints find major applications in water, sewage, and another liquid medium. The dismantling joint can be supplied which are suitable to be used with the flanged pipe.
We can offer dismantling joints that can be used with valves, pumps, and other application designs to perfection and easy to dismantle. We can offer dismantling joints from 50 mm nb to 2500 mm nb with varying thickness to suit various applications and as per clients’ requirements.
The installation is additionally straightforward using just a spanner and wrench to tighten the high tensile steel or chrome steel tie bars. With fewer tie bars than flange holes and therefore the tie bars acting as flange jointing bolts the method is sped up but still offers a secure, rigid, fully end load resistant system with a pressure rating adequate to that of the flange.
The Dismantling Joints are double flanged fittings that accommodate up to 100mm (4”) longitudinal adjustment and may be locked at the length with the tie bars supplied. Not only does this technique leave fast, easy maintenance of valves, pumps, or meters, it simplifies future pipe modifications and reduces downtime when changes got to be made.
A comprehensive range is out there from DN50 to DN2500 with virtually any flange drilling or pressure rating supplied, although larger sizes and custom made Dismantling Joints are often designed and built on request.
Never re-use this joint taking into account its important deformation. Even if the joint seems to be in good report, it should not be re-used. The price of a new joint is quite lower than the cost of work of assembling and disassembling of the joint because of later problems due to the re-use of the joint.
To transport the dismantling joints to its installation site, it should be packed in a stable, properly sized container. The container also needs to ensure that the dismantling joints are protected against weather influences and damage. When the dismantling joints are transported long-distance (e.g. overseas) and exposed to special climate , it must be protected by sealing it in plastic wrapping and adding a desiccant.
Visually inspect the dismantling joints for any signs of injury including scratches, loose parts, broken parts, or the other physical damage which will have occurred during shipment. If the damage is observed, immediately file a claim with the shipping carrier. If applicable, please photograph the damage detected on the dismantling joints. Dismantling joints that are damaged during transportation are the responsibility of the customer.
During storage, the dismantling joints should be protected against sand, dust, and any other impurities, and therefore the dismantling joints should be stored in a dry, well-ventilated area. Avoid long-term storage of the dismantling joints outdoors exposed to the effects of rain, sunlight, or frost. The direct exposure of the dismantling joints to radiation heat emitted by radiators should be avoided. It is also recommended to utilize the original shipping container and packing materials to properly store the dismantling joints.
Dismantling joints are designed for the easy assembly and disassembly of pipe sections and valves. Without dismantling joints it would be almost impossible to longitudinal adjust the valve or similar items with the pipeline when they are installed. This helps with the maintenance or replacement of pumps, valves, or similar items. Each fitting features a standard range of length adjustment of up to 50 mm and may accommodate limited lateral and angular misalignment.
Joints for establishing pipe connections have developed a long way. As a result, in today’s marketplace, there are many different types of mechanical joints
readily available, ranging from dedicated push-in socket joints, welded joints to wide tolerance joints covering various pipe materials.
Consequently, brute force has to be used to take the butterfly valve out, potentially resulting in damage or, even worse, the pipes having to be cut and later replaced by welding back a pipe and flange and/or inserting a mechanical joint. These efforts are time-consuming, increase the system’s downtime, and require additional components to be added to fix the situation.
Flange Adaptors are used to connect one plain-ended pipe to a flanged device, and mechanical couplings are used to connect two plain-ended pipes with each other. The Mechanical Couplings and Flange Adaptors of the UNI JOINT Range are of the dedicated type, which means they are designed for one specific pipe material (usually steel or ductile iron pipes). These are ideal for situations where the selected pipe materials, nominal sizes and pressure ratings are known in advance.
Below, we set out the most common types of mechanical joints and some of the key considerations when deciding between specifying a standard or bespoke, fabricated solution. We also examine why these fabricated mechanical joints are capable of meeting such demanding needs, looking at the aspects of the design and manufacturing process that make such a crucial difference to the end product and deliver key benefits for those operating water networks.
On top of this, they also allow (as standard by design) 3° of angular deflection per pipe. This allows connection to pipes that are misaligned and movement during service. In the case of couplings, this angular deflection also enables bends in pipeline systems.
