STAUFF ACT Clamps

STAUFF ACT Clamps are an innovatively designed solution for the installation of instrumentation pipework where anti-corrosion properties are of paramount importance (e.g. in the fields of offshore oil and gas exploration and processing).  

The design – based on the tried and tested STAUFF Clamps according to DIN 3015 – offers installation time reduction and long term cost savings due to extended service intervals. 

The STAUFF ACT clamp body design is available for the Standard Series (DIN 3015, Part 1) and the Twin Series (DIN 3015, Part 3) to cover the most commonly used metric and imperial pipe diameters from 6 mm to 42 mm (1/4 inch to 1 1/2 inch).

• Efficient Prevention of Crevice Corrosion under Pipe Clamps on Stainless Steel Pipework  

• Middle- and Long-Term Cost Savings due to Extended Service and Maintenance Intervals

• Design based on Original STAUFF Clamps according to DIN 3015, Parts 1 and 3 (Standard Series and Twin Series), the tried and tested industry standard for several decades 

• Covering the most commonly used metric and imperial pipe diameters from 6 mm to 42 mm (from 1/4 inch to 1 1/2 inch) 

• Alternative configurations and pipe diameters on request 

• Installation time reduction (compared to alternative designs) 

• Material and design in compliance with section 7.3 (Tubing Installation) of the Norwegian offshore standard Norsok Z-010 (Revision 3, published in October 2000 ), API RP 552 and NACE SP 0108-2008 (section 13)

• Material and design fully compliant with specification S-716 of the International Oil & Gas Producers Association (IOGP) for Small Bore Tubing and Fittings, which was prepared under Joint Industry Programme 33 (JIP33)

• Clamp body made of flame-retardant PP-V0 plastic material; tested and V0 classified according to UL 94 

• Integrated ACE anti-corrosion elastomer strips avoid the accumulation of seawater between clamp body and pipe 

• Drainage channels aid the dispersal of seawater (self-draining) 

• ACT Mounting Hardware is made of Stainless Steel V4A (Material Code: W55) with enhanced corrosion resistance by practically excluding metallic and non-metallic impurities during production, processing and handling (delivered in hermetically-sealed quality storage bags with 25 pieces each to avoid contamination during transport)  

• High UV stability of the clamp body material; resistant against seawater, rain and oil 

• Suitable for continuous exposure to temperatures from -25 °C to +80 °C 

• To be used in sub-sea and top-side environments; alleviating the requirement for two different products 

• Installation on Single and Double Weld Plates 

• Multi-Level Installation (with Weld Plates) 

• Installation in Channel Rails (with Channel Rail Adaptors) 

• Installation in Field Trays / Cable Ladders (with Hammerhead Bolts) 

• Multi-Level Installation in Field Trays / Cable Ladders (with Stacking & Hammerhead Bolts) 

• Multi-Level Installation in Field Trays / Cable Ladders (only with Hammerhead Bolts) 

• Subject to stringent testing at the STAUFF in-house laboratories located in Werdohl (Germany) 

• Salt spray tests according to ASTM B117 applied in controlled laboratory environments 

• Long-term field tested on a rig in the Dutch sector of the North Sea 

• Tests results independently assessed by Centre for Corrosion Technology at Sheffield Hallam University 

• Fully detailed, independent test reports available on request
