Product Description

Steel Expansion Joint Metal Pipe Joint

The metal pipe joint quickly connects valves, pumps, meters and pipe assemblies.Designed for ease of use, the expansion joint is easy to install and allows for fast periodical maintenance whenever required.

And was developed to provide greater versatility for the designer at the planning stage and the engineer in the installation stage of flanged pipe work systems and to allow for simple maintenance programmes.

1. Product Performance 
The product is manufactured through welding or metal casting, and the loosing part is sealed by echelon ring rubber. Operated by gland and bolt and based on the principle of rubber's elastic deformation under pressure, the seal ring will be deformed and static seal will be done between joint body and expansion pipe wall. According to clients demand and product performance, metal and seal ring materials will be selected strictly. High— Strength antifouling paint is painted outside and the joint bolt is made of high— Strength carbon steel or stainless steel, since there is some space between body and expansion, so axes and radial displacement will appear. Inside pipe, it becomes available to compensate and release pipe blind plate propulsion and makes it easy to maintain and change pump and valve. Therefore, it is an ideal matching product for pipe's installation and operation. 

2. Application Range 
The metal product is functioned with pull and pressure resistance and excellent seal performance and easy installation. Hence it is widely used in power, metallurgy, drainage and sewage disposal to connect pump, valve and pipe, etc. It also has some multi-directional displacement during pipes' operation so as to release blind plate propulsion and protect pipes, especially it makes it easy to install and maintain pipes. However, force-transferring joints shall be used on the pipe corner and pump exit, because, the joints can transfer blind plate propulsion from pump start to pump and pipe through force— Transferring bolt and prevent pull to centralize close to pipe or pump or damage equipment by impact force. Other joints can be selected freely for other positions. Our tenet: Your trust is our honor and will manufacture high— Quality products for you.

Functions

 

Allows for Adjustment 

The Steel Expansion Joint Metal Pipe Joint are double flanged fittings that accommodate up to 100mm (4”) longitudinal adjustment and can be locked at the required length with the tie bars supplied. Not only does this system allow for fast, easy maintenance of valves, pumps or meters, it simplifies future pipe work modifications and reduces downtime when changes need to be made.
Easy to Install

The installation is also straightforward using just a spanner and torque wrench to tighten the high tensile steelor stainless steel tie bars. With fewer tie bars than flange holes and the tie bars acting as flange jointing bolts the process is speeded up but still offers a secure, rigid, fully end load resistant system with a pressure rating equal to that of the flange.
The Range
A comprehensive range is available from DN40 (1½”) to DN2400 (80”) with virtually any flange drilling or pressure rating supplied, although larger sizes and custom made Dismantling Joints can be designed and built on request.

Full Flange Sealing 

For applications where a full-face flange is required, i.e. wafer and butterfl y valves, the flange of the spigot piece provides a full flange sealing area.
Excellent Corrosion Protection  

The flange adaptor and flange spigot are coated with WRAS approved Rilsan Nylon 11 providing excellent protection from transport, storage, site and corrosion damage. The tie bars are Zinc Plated as standard with other coatings, grades and finishes available on request. The nuts and bolts are Sheraplex coated to WIS-4-52-03, offering long term protection against corrosion.

Simple to Fit     

Harnessing is accommodated within the bolt circle, eliminating other complex anchoring systems and reducing space requirements.
Ultimate Sealing Capability   

The EPDM gasket in the dismantling joint is compressed independently of the tie bars with the sealing capability secured as soon as the fasteners reach required torque.
