ACL® SH DB SAF
ACL has now added the below sizes to the SH Safety Clamp range, in order to comply in part with AD2000 A5. The double bolt safety clamp enables the user to gain the advantage of a double bolt clamp whilst maintaining a majority of assembled components during scheduled maintenance intervals.
The clamps can be supplied with standard 316 fasteners, or alternatively with anti-galling materials (ref. ACL Anti-galling clamps).
Our single layer screen mesh gaskets range from 10 Mesh to 100 Mesh and are offered from stock with stainless steel inners & either Black EPDM or Clear Silicone outers – USP Class VI compliant. Alternative outers are available on request. The gaskets are unbonded therefore the mesh or outer can be replaced relatively easily.
Advanced Couplings Ltd are delighted to offer a Metal Detectable gasket – fully produced in the UK from UK sourced compound – to FDA & USP Class VI compliant grade.
The inclusion of ferrites in the compound make it metal & x-ray detectable so that any fragments of rubber, for example by abrasion or breakdown of the seal, can be identified by standard metal detectable software in use in Food & Pharmaceutical production lines.
Bends & Tees
We can now offer a range of clamp union ended bends (90° & 45°) and tees as an ancillary product for use with our standard range of clamp union fittings.
- BS 4825 & ASME BPE Standard
- Enhanced Surface Finished
- Imperial sizes stocked, other sizes available to order
Hex. Nut Design Improvement
In our efforts to continually improve our products we are introducing a change to the Domed Hexagon Nut used to tighten our range of clamps. These nuts are used to replace the Wing Nut in certain applications. The previous Domed Hexagon Nut was phased out from November 2017, and is replaced by the new Hexagon Flat Nut (see images below for comparison).
The Hexagon Flat Nut has the following advantages over the Domed Hexagon Nut;
- The contact point of the hexagon flat nut is only on the face of the clamp segment. This means the force is applied solely to a plane parallel to the nut face. This has benefits over the domed hexagon nut which has a contact point inside the legs of the clamp segment.
- In addition to the above, galling tends to be reduced as the thread at the tip of the nut is not deformed with use. This damage often results in a tighter thread which has been seen on multiple applications.
- The hexagon flat nut also maintains the perpendicularity of the thread to the clamp body. This reduces the off-collinear misalignment of the thread further reducing the tendency to gall.
