VMP SU Rectangular membrane

Producer: RSBP

The VMP safety rupture disc is designed for the passive explosion protection of process equipment with combustible dust and air in accordance with EN 1127-1. It releases and discharges explosion products into the environment.

In fail-safe condition, the membrane seals the openings in the equipment to be protected. In the event of an explosion, it opens and releases the flames and shockwave to the outside. The pressure in the equipment drops to safe values and there is no destruction of the structure.

Description

VMP SU rectangular explosion membrane is made of stainless steel. Due to its three-layer design it is suitable for protection of equipment with pressure pulses and operating temperatures up to 240 °C. It is resistant to overpressure.

VMP bursting discs are certified according to TP TC 012/2011 and EN 14797.

Advantages

Suitable for operating conditions with temperatures up to 240 °C. Resistant to mechanical damage, vacuum and pressure pulses.
Large selection of sizes allows a suitable rupture disc to be fitted to most types of process equipment.
Easy to assemble – only two steps are required for assembly, using the pre-drawn drawing sets and assembly instructions.
Easy to maintain – we will give you a detailed operating manual, describing the frequency of all operations. The customer’s employees are only required to visually inspect the cleanliness and integrity of the blast panel.
Easy to replace after an accident. Can be installed without altering the structure of the existing process equipment.
Only requires maintenance once a year, which reduces the cost of operation.

Installation

VMP SU is supplied either with top frame, seal or separately. The safety rupture disk must be checked before installation:

Integrity of the original packaging;
The membrane itself and the seals are undamaged;
The connecting material is present, if it is included in the scope of delivery;
No damage to the indicator, if ordered.

The installation of rupture discs requires a design. It determines, among other things, the number of process openings on the equipment to be protected to release the explosion and the number of VMPs respectively, their type, the possibility of operation under existing conditions. The project is to be developed by a specialized company. For example, ATEX.CENTER.

The rupture discs are installed in accordance with the manufacturer’s instructions and the explosion protection project. The work consists of two basic steps. First, the mechanical installation is performed, followed by the installation and adjustment of the electrical part.

The installation of each membrane must be recorded in a special logbook or operating book with the date, initials and signature of the authorised person.

The scope of delivery includes:

Consignment note
EU Declaration of Conformity 2014/34/EU;
Inspection certificate;
Operating instructions.

We will provide on request:

wiring diagram of the indicator;
technical description of the opening indicator;
technical description of the spark protection relay;
Panel wiring diagram;
Checklist;
The operating logbook.

Maintenance

The maintenance manual is included in the scope of delivery and is used as a basis for the operator’s documentation. In this manual, the maintenance intervals are determined.

Maintenance of the membrane consists of periodic inspection for cleanliness and damage, corrosion. Basic rules:

All operations must only be carried out with the equipment switched off;
Inspect the VMP for cleanliness and damage every shift;
Perform dusting and screw connection checks at least every six months or more frequently depending on the operating conditions;
Instruct employees on safety measures when working near the explosive membrane immediately after its installation (hiring a new employee) and at least once a year thereafter – the VMP is classified as an injury-prone equipment;
Do not enter the frame space and safety area when the equipment is in operation.

The safety rupture disc may only be serviced by the manufacturer, RSBP, or its authorised representative. The service interval is at least once a year.

Optionally

VMP can be equipped with:

Door opening indicator. This is a diaphragm status indicator. If the VMP is opened the contact will be interrupted and the electrical circuit will be disconnected. The indicators can be magnetic or cable.
Mounting kits for G1, G2 and G indicators. To be supplied on request.
Intrinsic safety relay. Intrinsic safety relays are hazardous for life. The relay creates a boundary between the safe and hazardous area.
Frames for VMP (type SU and D). Needed for mounting those membranes where there are no built-in frames. Made of stainless steel.
Flanged seals. As standard they are made of EPDM material. As an option it can be replaced with silicone (FDA).
Thermal insulation. Available on request.
