Loading and unloading equipment

The OSN-SNS bottom discharge arm is designed for safe and efficient unloading of petroleum, aggressive, and food liquids from railway tankers through the bottom nozzle. It uses full-bore stainless steel swivel joints approved for explosive areas by Rostekhnadzor. The unit supports over 9000 cycles without leaks and has a service life of at least 10 years. Supplied with a durable spring compensator for reliable operation.

This liquid phase loading arm enables safe and sealed transfer of liquefied hydrocarbon gases to and from tank cars. Equipped with PCT swivel joints and flexible connections, it adapts to various valve configurations. Quick couplings ensure fast connection, while relief valves and hoses provide safe depressurization after operation.

The OSN-UZG-050 drain stand unit is designed for efficient tanker unloading. It features a flexible pipeline system with PST joints and a quick coupler, allowing easy and secure connection regardless of valve position. Safety is enhanced by dual ball valves and a pressure release hose, ensuring safe operation under varying field conditions.

Loading and unloading is performed through two valves for the liquid phase and one vapor recovery valve on the tank hatch. The unit consists of two risers: a liquid phase loading/unloading riser with two quick couplers and a vapor phase drain riser with one quick coupler.

This stainless steel clamp is designed for the safe loading and unloading of liquefied hydrocarbon gases in rail tankers. It securely attaches riser pipes to the tank’s top valves and prevents sparks during contact with equipment. Its quick-release design simplifies operation and enhances safety in fire-prone industrial environments such as the oil, gas, and chemical sectors.

A standard drop pipe is used in tanker loading systems for safe and controlled fluid transfer. Made from carbon steel, stainless steel, or aluminum alloy, it can be configured to prevent sparking and jet reactivity. When sealed with a cap, the liquid is released from the sides, ensuring smooth flow without impact. Its standard length is 1800 mm, but can be tailored to specific tanker dimensions as needed.

The standard support is used in open tanker filling to securely hold the top loading arm. It also provides a mount for a vibration-based emergency level sensor, which is fixed at the required height inside a protective cylinder with perforations. This design ensures liquid level equalization and safe, reliable operation in industrial conditions.

Top loading arms for road and rail tankers — reliable equipment for loading petroleum products and liquids, compliant with GOST standards.

The vapor-sealing cover is designed for use in closed loading operations. It minimizes vapor leaks from the tank and is compatible with various tanker hatch designs. Its construction includes a rotatable ring with rollers for easy alignment and a connector for vapor recovery systems. It also features a mechanism for attaching a level sensor, following the same principle as on standard support systems. This design ensures reliable and environmentally safe operation.
