Detailed Product Description

Slot Dipping Device

The Slot Dipping Device has been designed to provide a convenient and safe means of manually measuring the levels and temperature and taking samples of petroleum, petrochemical, chemical and other volatile or hazardous liquids in bulk storage tanks, in pressures of upt 40" (1016 mm) WG.  It is available in 6" (150mm) size and is mounted on the roofs of tanks and can be used in place of conventional gauge hatches with the following advantages:

• Negligible loss of vapour
• Operations not exposed to hazardous vapours
• No product spillage due to wiping of the tape

The device can accommodate both heavy and light dip weights and also the Temperature and Sampling Device.

The Temperature and Sampling Device has been designed to provide a means of taking samples and temperature of products stores in bulk in the petroleum, petrochemical, chemical and allied industries.  When used in conjuction with the Slot Dipping Device which is suitable for pressures upto 40" (1016 mm) WG. loss of vapour is greatly reduced.

Servicing

All tank environmental protection equipments can be supported by our service department who can provide expert and specialist installtion and commissioning service and complete 'on site' equipment maintenance, repair and servicing faclities including equipment condition surveying and certification and maintenance training.

Operation

Tape adaptor has a small clearance around the tape through which only a very small amount of vapour can escape and is permanently attached to the tape.  When the upper section of the device is isolated from the tank by the closure pallet the plug can be removed and the tape weight inserted with the tape adaptor replacing the plug.  Gauging can proceed when closre pallet has been lowered.  Indicating paste is normally used when gauging spirit tanks.  When gauging black oil tanks it is advisable to use the adaptor which incorporates a tape wiper.

Sampling

Eighter a gauging tape or a PVC covered wire rope can be used with the corresponding adaptor.  The method of sampling follows closely that for gauging except that the cap on the upper chamber is opened and the sampling device is placed in the upper section and the tape/ rope connected.  The tape adaptor or rope adaptor is inserted in the cap and after lowering the pallet, sampling can proceed.
