Semi-Subsurface Foam Injection Device

Product catalog summary

General Description: The document describes a foam injecting device designed to deliver expanded foam to the liquid surface in storage tanks via a flexible hose. It is particularly used in tanks containing water-soluble flammable liquids or where fuel pick-up by foam is not acceptable.

Application Description: The device is suitable for applications requiring expanded foam delivery to the surface of storage tanks. It is recommended to refer to Datasheet 1008/11 for details on the foam sealing membrane SM.

Selection Table: The document provides a selection table for different application rates (4.1, 6.5, and 10 l/min/m2) and corresponding tank diameters, specifying the appropriate HSSS model numbers.

Product Features: Key features include direct surface foam delivery, a leakage warning device, air bleed device, stainless steel body, and a large capacity range up to 2500 l/min. It is suitable for tank heights between 13m and 28m and for polar-solvent liquids.

Connections: The device has flanged inlet/outlet connections according to DIN PN16 or ANSI 150lbs standards.

Optional Components: Optional components include a check valve, expander, and gate valve.

Listings or Approvals: All models are FM approved.

Order Information: When ordering, specify size, flange type (DIN or ANSI), and length of hose/tank height.

Performance Data: The document provides detailed performance data for different HSSS models, including water capacity, maximum tank height, required opening pressure, maximum back pressure, dimensions, connection sizes, maximum working pressure, and weight.

Material Specifications: The materials used include stainless steel for the hose container and foam sealing membrane, nylon for the hose, and galvanized steel for distance parts and flanges.

Installation and Operation: The document includes a typical installation arrangement at the tank base and mentions the use of a high back pressure foam generator system.
