2 UNIJOINT Flange Adaptors & Couplings

UNIJOINT, established in 1992 in the Netherlands, is a company with a vast experience in the engineering, manufacturing and marketing of high quality couplings, flange adaptors and dismantling joints. Since 2010 UNIJOINT belongs to the Talis-Group. With 10 strong brands, TALIS offers a comprehensive range of valves and services for the whole water cycle. From water recuperation to communal water distribution. From water transport to sewage treatment. With more than 20,000 products, TALIS has the most varied range on the market.

UNIJOINT offers additional possibilities on top of their standard range. The UNIJOINT engineering team is used to designing products tailored to specific customer needs e.g. with specific face to face lengths, special materials or alternative coatings. Our products can be designed to meet working pressures of 100 bar and beyond and to diameters beyond DN 4000. UNIJOINT is also able to provide project management and reporting, dedicated testing such as hydro-static pressure testing or weld inspections, documentation such as test reports, 2.2 & 3.1 material certificates, bespoke drawings or technical reports, as well as third party inspections.

UNIJOINT products can be combined perfectly with all products in the wide TALIS range such as gate valves, butterfly valves, return flow inhibitors and fit-tings as well as products from other manufactures. Quality and service are the core competences of the UNIJOINT team. Therefore we are proud to present UNIJOINT as your partner for challenging pipe connections.

3UNIJOINT Flange Adaptors & Couplings

Unijoint is the specialist when it comes to dismantling joints, flange adaptors and couplings.

The design principleAlthough there are numerous versions of flange adaptors and couplings avail-able, the basic design principle is the same for all versions:•Couplings are the flexible solution for joining two pipes. Couplings consist of

two follower end rings, a middle ring, two gaskets and a set of bolts and nuts. Each rubber gasket is contained in a compression chamber which is formed by the follower end rings, middle ring and pipe surface. By thightening the coupling‘s bolts, the follower end rings are drawn together, thus reducing the volume of the compression chambers and compressing the gaskets, resulting in a pressure tight seal.

•Flange adaptors consist of one follower end ring, a middle ring and flange, one gasket and a set of bolts and nuts. Flange adaptors are ideal for joining a pipe to a flanged product like for instance a gate valve, butterfly valve, return flow inhibitors or fittings in general. Similar to a coupling, the compression chamber is formed by the follower end ring, middle ring and pipe surface. UNIJOINT flange adaptors can be equipped with flanges to any standard.

•In order to ensure that couplings and flange adaptors give a lifetime of trouble free service, the gasket is compressed well above the pressure needed to form a pressure tight seal. This compensates for rubber creep, which may occur due to flunctuations in temperature, pressure, and general loss of strength in rubber products over a period of time.

•To ensure a correct fit, over a length of of 250 mm pipe ends must be within the following tolerances and ovality:

1. Follower end ring2. Gasket3. Middle ring4. Bolts, nuts & washers 5. Pipe surface

UNIJOINT Eurocoup flange adaptors: the straightforward solution

The UNIJOINT Eurocoup flange adaptors are the most basic type of dismantling joint. On one side, it has a flange connection in accordance with the required flange standard, on the other an insertion socket for the pipe. A variety of stand-ard pipe types can be connected.

Since the UNIJOINT flange adaptor does not offer end load restraint, it requires a fixed point in the pipeline. If the pipe end can be pulled out of the flange adap-tor, anchoring is required. The UNIJOINT flange adaptor has an expansion and contraction of ± 2,5 mm for the gasket, and offers an adjustability of ± 25 mm during installation as well an angular deflection of 3°. The UNIJOINT flange adaptor absorbs vibrations in the pipeline, overcomes axial offset and guaran-tees a permanently leaktight connection. UNIJOINT Eurocoup dedicated flange adaptors are available for a variety of pipe types. The anti- torque bolts also make the flange adaptor suitable for a fast “ one-man installation ”.

UNIJOINT Eurocoup couplings are the flexible solution for joining pipes. These couplings are ideal for absorbing noises and vibrations in pipelines and over-coming axial offset, guaranteeing a permanently leaktight connection.

Each rubber gasket is contained in a compression chamber which is formed by the follower end rings, middle ring and pipe surface. By thightening the cou-pling‘s bolts, the follower end rings are drawn together, thus reducing the vol-ume of the compression chambers and compressing the gaskets, resulting in a pressure tight seal. The UNIJOINT Eurocoup coupling allows an expansion and contraction of ± 2,5 mm and an angular deflection of 3° for each gasket (± 5 mm & 6° in total for each coupling)

The UNIJOINT Eurocoup dedicated couplings can be delivered in standard and non-standard designs e.g. stepped couplings and special couplings for high working pressures up to 100 bar. For diameters above DN 300, UNIJOINT is able to manufacture products for any outer pipe diameter according to any existing pipe standard on customers request. Non- standard coatings and higher steel grades are also available on request.

UNIJOINT stepped flange adaptors are the ideal solution for situations where the nominal diameter of a pipe is larger (or smaller) than the nominal diam-eter of the flange. Stepped flange adaptors are available for any standard and non-standard outer pipe diameter [sizes greater than DN 300] and are specially engineered to ensure a perfect and leaktight connection.

Similar to the UNIJOINT Eurocoup flange adaptors, these stepped flange adap-tors allow an angular deflection of 3° and an expansion and contraction of ± 2,5 mm for the gasket. Furthermore these stepped flange adaptors can be equipped with flanges according to any existing flange norm.

In cases where stepped flange adaptors are needed, it is best to consult with our engineering department. This will ensure a perfect design, specifically engi-neered for your specific problem.

UNIJOINT stepped couplings are the ideal solution for situations where pipe ends with different outer diameters have to be joined. These couplings are spe-cially engineered based on the lay-out of the pipeline. Similar to the dedicated Eurocoup couplings, the UNIJOINT stepped couplings are ideal for absorbing noises and vibrations in pipelines and overcoming axial offset which guarantees a permanently leaktight connection.

Stepped couplings are available for diameters greater than DN 300. Depending on the gap between both pipes to be connected, the UNIJOINT stepped coupling will be constructed with a flange in the middle. In case of a situation where dif-ferent pipe diameters have to be connected we advise to consult with our engi-neering department. It is of great importance to know what the outer diameter of each pipe end is and if the pipe ends are correctly calibrated. Other important factors are the medium going through the pipeline and the maximum working pressure.

All variants correspond to the world leading AWWA C219 standard, and are manufactured in Europe using top material qualities in a precise process.•Specially developed expanders are used for steel production, where the

rings are expanded outwards evenly under heavy pressure. This guarantees an absolutely round product with minimum tolerances to satisfy hydrostatic pressure testing according to AWWA C219.

•The high quality bolts, nuts and washers - key for a sturdy, leaktight design - are made of hot dip galvanized steel, with stainless steel versions available as an option.

•Only high-quality EPDM or NBR rubber compound qualities for water, drink-ing water and sewerage are used for the gasket. These guarantee a clean, leaktight seal for years, and at the same time allow angular deflection and pipe movement.

•The surfaces of all metal parts, apart from the bolts, nuts and washers are protected from corrosion by a fusion bonded epoxy [FBE] coating with a dry

film thickness of 305 µm. Further coatings are available as options, e.g. Rilsan, EPC, enamel, liquid varnishes [suitable for drinking water] or other special outer coatings. Inner rubber coatings suchs as ebonite are also avail-able. The choice of coating depends on the requirements resulting from the medium to be used and customer wishes.
