The Ventilation Nozzle (PV) is designed for ventilating tanks and preventing foreign objects from entering them. Ventilation nozzles of various designs are installed on tanks containing low-evaporation petroleum products to maintain constant communication between the tank's vapor space and the atmosphere. For tanks storing petroleum products with a vapor flash point below 120°C, the ventilation nozzle is installed with a flame arrester.
This nozzle is a component of vertical cylindrical tanks used for storing petroleum products.
The minimum throughput capacity of the ventilation nozzle is determined based on the maximum performance of receiving and dispensing operations (including emergency conditions) according to established formulas.
In terms of resistance to environmental climatic factors, the nozzle complies with U and UHL versions of placement category 1 according to GOST 15150-69.
---The Mounting Nozzle (PM) is intended for installing technological equipment (such as breathing valves and ventilation nozzles) necessary for tank operation. It is installed on horizontal and vertical tanks for storing oil, petroleum products, and chemical liquids.
In terms of resistance to environmental climatic factors, the nozzle complies with U and UHL versions of placement category 1 according to GOST 15150-69.
---The Receiving and Dispensing Nozzle (PPR) is designed for mounting various types of shut-off valves and technological equipment, and it is installed in the lower part of the tank. This nozzle is also used for filling and emptying operations of the stored tank products.
In terms of resistance to environmental climatic factors, the nozzle complies with U and UHL versions of placement category 1 according to GOST 15150-69.
---The Measuring Hatch (LZ) is designed for measuring levels and taking samples of petroleum products in oil depot and gas station tanks.
Measuring hatches (LZ) are characterized by ease of maintenance, convenience of use, low weight, and overall structural durability.
In terms of resistance to environmental climatic factors, the nozzle complies with U and UHL versions of placement category 1 according to GOST 15150-69.
---The Sight Hatch (LS) is designed for inspecting and ventilating the internal space of a tank during repair and cleaning, as well as for performing installation work for equipment inside tanks.
In terms of resistance to environmental climatic factors, the nozzle complies with U and UHL versions of placement category 1 according to GOST 15150-69.
---The Manhole (LL) is designed for internal inspection, repair, or cleaning of vertical steel tanks. Manholes are manufactured in two versions: round and oval.
The manhole is installed on the vertical wall of a steel tank and welded to the body through a reinforcing pad. Upon customer request, the manhole can be equipped with a swivel device.
In terms of resistance to environmental climatic factors, the nozzle complies with U and UHL versions of placement category 1 according to GOST 15150-69.

To connect tanks and apparatus to pipelines and install various fittings, special pipe sections called **nozzles** are installed, mounted, and welded in.
**Manholes** and **nozzles** fall under the category of tank equipment and are positioned to maximize operational efficiency. Manholes and nozzles are produced from the same material as the tank walls to which they are installed. Analogues that match the physicochemical properties of the main material by 80 percent are permitted.
To purchase a manhole, you need to submit a request using any convenient method, paying attention to the following characteristics:
· **body shape** – round or oval;
· **nominal diameter**;
· the letter **"P" in the marking** indicates the presence of a swivel device, facilitating the opening and closing of the manhole;
· the letters **"T" and "U"** – climate version options.
Our production of manholes is certified, and each product undergoes all necessary leak tightness tests.
