1.0 Description Emergency Release Breakaway

1.1 Area of use

The Emergency Release Coubling (NTS-PU) can be used in loading arms, hoses- and pipelines forthe transfer of fluids or gas.

Typical application :

Ship loading and unloading Loading arm systems Ship to ship transfer Ship to onshore Onshore and offshore service pipe-lines Subsea manifolds

1.2 Design

Both halves of this emergency coupling are equipped with non returning, spring loaded valves; theyare held together by a fast coupling connection. Separation is triggered by a pulling force via thehose or loading arm. The separation force is individually preset for max. protection of the hoseline.

1.3 Function

In the mounted status the NTS-PU is open and allows for free flow. If a tensile force exceeds thepreset value the two halves separate. The valves instantly close on both ends to prevent spillage.The separation does not result in the destruction of parts (shear pins); no spare parts or specialtools are required to instantly reassemble it after depressurizing and draining the hose line.

1.4 Advantages

Working in any direction (angle)

Built-in either direction possible or assembled in either flow direction

Easy reassembly after separation

Mounting: tighten mounting screws, push 2 halves together and remove themounting screws

Cable-free activation

Fully functional immediately after being built in; no further activation required

Spare-part-free, non-destructive separation

No shear pins involved and no destruction.

Easily reassembled w/o tools or spare parts

Ideal for LPG transfer lines

1.7 Approvals

CE-marked, Type-examination (Module B) according to Directive 97/23/EC ATEX, Manufactures Certificate of conformance according to Directive 94/9/EC (ATEX) Conform with clean air regulation (TA-Luft) Manufactured under DIN EN ISO 9001:2008


2.0 User Manual - NTS-PU

2.1 Installment:

1. To assure a safe function the NTS-PU needs to be installed as follows:a. Tensile force either axial or at an angleb. The coupling halves need to have enough space to fully separate.

This guarantees the complete closure of the valves.

For all sizes 6” - 12” (DN150 – DN300) the minimal required distance between the twohalves is 8’’ (200mm) at the point of separation.

2. The ARTA NTS-PU can be installed in any direction.

3. Installation should not lead to stress on the production line.

4. Mounting screws must be removed before the use of the NTS-PU

5. During the separation small amounts of media could escape. We therefore recommend anadditional spray protection.

6. The user manual (installation instructions) and the mounting screws should be kept in secureand accessible location.

Caution!The Valves of the NTS-PU are spring loaded.

Inappropriate disassembly could lead to injuries!

7. Warning !!!!!!!!!!

During the (un)fueling process no person should be standing in the danger zone of the NTS.The separated hose end might pose an injury danger during the separation process.Emergency contingencies are to be followed according to local regulations and jurisdictions.


2.2 Reassembly of the NTS-PU after separation

1. Depressurize and empty the hose / loading arm

2. Inspect both coupling halves for possible damage

3. Check valves manually for easy function

4. Evenly apply mounting screws to release levers

5. Place the two valve pins on top of each other and press the top halve downward into the bottomhalve. Then carefully remove the mounting screws while still holding down the top halve untilthe connecting elements engage

6. Do not conduct the final leakage test with air


2.3 Assembly / Manual

1. We recommend for the transport eyebolts and suitable lifting belts

2. Use a suitable lifting device and a solid frame for the assembly !!!!!!!!!!

eyebolts


3. Screw in (assemble) the allen screws. The lever then opens to allow reconnection

4. Screw in the four threaded rods

3.0 Test – and Maintenance recommendations – NTS-PU

3.1 Test periods of the Emergency Release Coupler

Independently from governmental regulations, we recommend to test Emergency ReleaseCouplers at least once a year according to the test recommendations for thermoplastic,elastomer-type hoses.

A more vigorous use requires shorter test intervals. Elevated temperatures, higherconcentrations, impurities and abrasive particles can significantly influence the corrosionresistance in Emergency Release Couplers.

3.2 Test procedure

Test procedures are regulated by the local plant safety committee. It could involve for examplepressure test of both coupler halves or the mounted coupler, a separation test and/or visualinspection.The results need to be documented.

3.3 Pressure testing the coupling halves

Test both halves individually (adaptor and inline) for leakage. Mount the threaded end (flange)of the separated halve to the test unit and pressurize the system with fluid up to the requiredworking pressure. Increase the pressure stepwise and check for leakage.

3.4 Pressure testing of the mounted NTS-PU

Close the coupler on one side with a blind threaded end / blind flange and fill with fluid in anupright position. Apply the test connection and pressurize the system to the requested workingpressure. Increase the pressure stepwise and check for leakage.

3.5 Separation testing

Build in the NTS-PU in an axial fashion and trigger the separation with e.g. a cable winch. Theuse of a tensile force meter is recommended.

3.6 Maintenance

All ARTA® Emergency Release Couplers (breakaways) have minimal need for maintenance. Allguiding elements, o-rings and seal rings should be periodically checked for porosity as well asfor wear and tear.

Upon request, we can train the operating staff.

Spare parts for ARTA® Emergency Release Couplers (breakaways) can be ordered with therespective part number and product identification which can be found engraved onto thecoupler.

3.7 Repairs

Repairs to the ARTA® Emergency Release Couplers (breakaways) can only be performed bytrained and authorized personnel followed by subsequent testing, labeling and documentation.The spare parts available for many years.

3.8 Cleaning

The NTS-PU needs to be thoroughly cleaned before any repair.
