Working in conjunction with a leading tank safety specialist, we have designed the OsecoElfab Intermodal Container Disc (ICD) specifically for manufacturers of intermodal tanks and other vessels used to transport dangerous goods. The ICD meets the international standards required for this.

The OsecoElfab ICD is solid metal disc with a non-fragmenting design. Score lines on the convex side of this forward-acting disc ensure material will not buildup on the media-facing side. Additionally, the disc can be fully lined on the process side to prevent contact between the metal and any corrosive media.

The ICD is supplied complete with inlet and outlet gaskets. The disc will withstand full vacuum with no additional vacuum support required. The non-fragmenting design offers full bore relief in the event of a rupture, making the ICD excellent for use in conjunction with safety relief valves.

As manufactured in North Shields (EMEA/APAC), the ICD is a holderless disc for installation directly between industry-standard flange fittings. The disc is self-aligning for failsafe installation. It is supplied as standard with a laser-etched stainless steel tag for full traceability.

The version manufactured in Broken Arrow (AMR) is designed to fit standard threaded or bolted railroad tank car safety vents, using the FAS disc and insert holder.
