Advanced Couplings – Clamps

Standard Clamps

Advanced Couplings clamps are designed and manufactured for use in the Food & Dairy, Chemical and Pharmaceutical industries where standard tube/pipe couplings are required. Clamp components are produced from stainless steel using the lost wax process. The assembled components are then barrel polished to produce the high quality finish demanded throughout the industry. Quality and precision in manufacture combined with the unique patented design of our groove profile, produce a clamp with the best joint efficiency for this type of connection..

SSH Type Pharmaceutical Clamp

Material: 304/1.4301 – 1.4401
Application: Heavy Duty
Hinge Lay-Out: Separate Segments

The heavy duty clamp in the Advanced Couplings standard range. This clamp has a double bolt configuration, and is available in 304 stainless steel material as standard, with pressure ratings certified by Forbairt. All SSH Clamps are supplied with brass nuts, aiding repeated assembling and disassembling operations by alleviating the usual thread damage of heavy duty clamps, although stainless steel nuts are available on request. Sizes range from ½” through to 8 5/8”.

Pharmaceutical Clamp for ASME VIII Pressure Vessels

Material: 316 / 1.4401
Application: Pressure Vessel
Hinge Lay-Out: Hinge Plate & Safety Bolt

This clamp is designed to meet the exacting requirements of the ASME VIII pressure vessel design code division 1, as given in Appendix 24. With a double bolt configuration at one lug side plus hinge plate and bolt at the other, the requirements of offering a secondary restraint in the eventuality of primary bolt failure is satisfied. All ASME VIII Clamps are supplied with complete 316 stainless steel component material certification, as required by ASME VIII Pressure Vessel Design. Published pressure ratings were calculated using the theoretical equations and exacting requirements given in the Pressure Vessel Code, a copy of Advanced Couplings’ working equations can be supplied upon request.

Safety Clamps

Advanced Couplings have added to their product range of clamps with the introduction of the SH Style Safety Clamp. Developed using the template of AC‘s market leading SH Clamp, they have designed and manufactured the patented Safety Clamp to improve operator safety throughout the industry, targeting hazardous high temperature steam lines.

SAF Type Pharmaceutical Safety Clamp

Material: 316/1.4401
Application: Normal / Heavy Duty
Safety Feature: Safety Gate & Eye-Bolt

The ‘gate’ style section combined with the stepped eye-bolt ensures that the clamps bolting mechanism cannot swing open whilst the clamping union is part or fully assembled. Releasing the clamp is only possible when the wing nut has been significantly loosened to enable the smaller diameter of the eyebolt to swing and pass through the sectioned gate; this ensures the clamp cannot be knocked or accidentally opened. Complete wing-nut removal is not necessary to open the clamp but the design guarantees that the eye-bolt cannot swing open whilst the union is subjected to either clamping forces or internal pressures.

SAFX Type Pharmaceutical Safety Clamp

Material: 316/1.4401
Application: Normal / Heavy Duty
Safety Feature: Safety Gate, Eye-Bolt & Nut

The ‘gate’ style section combined with the stepped eye-bolt ensures that the clamps bolting mechanism cannot swing open whilst the clamping union is part or fully assembled. Releasing the clamp is only possible when the wing nut has been significantly loosened to enable the smaller diameter of the eyebolt to swing and pass through the sectioned gate; this ensures the clamp cannot be knocked or accidentally opened. Complete wing-nut removal is not necessary to open the clamp but the design guarantees that the eye-bolt cannot swing open whilst the union is subjected to either clamping forces or internal pressures.

SAFS Type Pharmaceutical Safety Clamp

Material: 316/1.4401
Application: Normal / Heavy Duty
Safety Feature: Safety Gate, Eye-Bolt & Shroud

The Shrouded Safety Clamp is based around the design principal of the standard SH safety clamp. This new variation benefits from the added safety feature of a domed nut replacing the wing nut. Using the domed nut guarantees that the clamp cannot be loosened by hand. This coupled with the added security of the free rotating nut shroud determines that the clamp can only be released using the correct socket adapter, alleviating problems where the piping line can easily be tampered with or accidentally released.

SAFL Type Pharmaceutical Safety Clamp

Material: 316/1.4404
Application: Normal / Heavy Duty
Safety Feature: Safety Gate, Eye-Bolt & Padlock

The Lock-Out Safety Clamp is an advanced version of the Shrouded Safety Clamp. The wing-nut has again been replaced with a shrouded domed nut. The shroud however is extended in length and modified to accept a number coded or key operated padlock. Once the clamp has been assembled, the padlock’s shackle can be passed through the holes in the nut shroud stopping the hexagon head of the nut from being accessed and loosened by a spanner or socket set. The Lockout Safety Clamp ensures the process / piping line can only be accessed by a designated maintenance engineer who has the padlock’s key / number combination.

3 Segment SAF3 Type Pharmaceutical Safety Clamp

Material: 304/1.4301
Application: Light – Normal Duty
Safety Feature: Safety Gate & Eye-Bolt

The ‘gate’ style section combined with the stepped eyebolt ensures that the clamps bolting mechanism cannot swing open whilst the clamping union is part or fully assembled. Releasing the clamp is only possible when the wing nut has been significantly loosened to enable the smaller diameter of the eyebolt to swing and pass through the sectioned gate; this ensures the clamp cannot be knocked or accidentally opened. Complete wing-nut removal is not necessary to open the clamp but the design guarantees that the eye-bolt cannot swing open whilst the union is subjected to either clamping forces or internal pressures.
