WATER HEAT-PROTECTIVE SCREEN (VPE)
TU 28.99.39-049-72410778-2018
Purpose and scope
The water heat-protective screen (VPE) is intended to reduce the exposure of an operator (nozzleman) or equipment to flame thermal radiation in case of fire.
The water screens are designed for use is a system with firefighting monitors and fire towers at facilities associated with the negative effects of heat flow on either operator or equipment.
The use of water screens is provided for by the requirements of SP 155.13130, SP 231.1311500.2015, SP 326.1311500.2017, as well as in the revision of SP “Racks for flammable, combustible liquids and liquefied hydrocarbon gases at oil refining and petrochemical enterprises. Fire safety requirements".
Distinctive advantages
- Simple and reliable design.
- Usability.
- Increased protection against the screen destruction when used in conditions of variable temperatures (fire conditions - negative outside air temperatures).
- Extra nozzle opening protection.
Materials of manufacture
Climatic models U, HL, UHL, T, OM: housing and details - stainless steel.
