BP420 - Burst plugs

The Dynisco Model BP420 burst plugs are specifically designed for use in plastic extrusion systems. Burst Plugs (also known as rupture disks) are designed for reliable, emergency relief of excess pressure in a system. The Model BP420 will instantaneously rupture at a specific, predetermined pressure and temperature. Each one-piece assembly consists of a 304 stainless steel body with a welded Inconel rupture disk. The disk is flush with the tip of the burst plug with no cavity for product build-up. A burst plug may be specified for primary relief in applications where pressure build-up can occur so rapidly that the response time of a relief valve is inadequate, such as in polymerization reaction vessels.

All burst plugs are tested at rated burst pressure and temperature. In addition, markings on the burst plugs are laser engraved, more visible, and each is labeled and shipped with protective packaging.

Ordering Guide for Burst Plugs BP420 Series

BP420 - Dimensions  

All dimensions are inches (mm) unless otherwise specified.

Transducer Mounting Hole Cleaning Tool Kit

Installation of transducers into improperly cleaned or sized holes is one of the major causes of damage to these instruments. With this kit, the .312" tip diameter hole, the 45 degree seating surface, and the .451" hole can be cleaned. The kit includes a gauging plug which is used to verify that the hole has been correctly machined and cleaned. M10 and M18 cleaning kits also available.
 

Transducer Mounting Hole Machining Tool Kit

The Dynisco Transducer Mounting Hole Machining Tool Kit contains all of the necessary drills and taps to prepare a standard 1/2 - 20 UNF transducer mounting hole and the 45 degree seat. All tools included in this kit are made of premium grade, high strength tool steel. Care should be taken in the use of proper speeds and feeds, lubricants, and a method to assure continual alignment of each progressing tool. M10 and M18 kits are also available.

BP520 - Burst plugs with indication

The BP520 series of pressure fuses have a "pop-up" indicator cap. A fine conductor passes through the construction of the fuse and the indicator cover of the part, which, when the fuse is activated or by emergency release of pressure, pushes out the fuse cover and thus disconnects (ruptures) the tested conductor.
