Top Loading Arms

KANON top loading arms are specially designed to suit both open filling of a wide range of products across all industry sectors or closed filling of the type of highly aggressive liquids associated with the chemical and petrochemical industries.

Loading arms can be manufactured for every application, and following years of experience, KANON have developed, and continue to develop, widely accepted solutions for filling tankers.

The three basic top loading styles are:

1) Single Top Loading Arm
2) Single Top Loading Arm with vapour return or pressure line
3) Single Top Loading Arm for vapour return


Top loading arms can be provided with various useful accessories (as shown later in this brochure) including:

• Top level detection: (bubble pipe sensing or electronic)
• Press down cylinder to prevent the arm lifting
• Drop pipe deflector
• Telescopic drop pipe (preventing foaming or electrostatic build up)

Where required, top loading arms can be provided with heat-tracing, jacketing and insulation.

1) Single Top Loading Arm. Usually equipped with four swivel joints, and with or without a cone, the standard loading arm offers great flexibility and covers the complete range of manhole sizes as found on most tankers. For closed filling applications additional swivel joints can be included in the drop pipe to ensure stress free connections.

Semi-closed loading incorporating a cone in combination with a vapour line either hard piped to form a double top loading arm, or flexible and piggyback mounted on a single product arm is the more typical design. This solution offers effective vapour return whilst maintaining flexibility for the tanker fleet.

Alternatively, fully closed loading using secure flanges, or specific couplings, provides a true ‘closed loop’. However, mating connections are required on both the loading arm and tanker top dictating the need for a dedicated tanker fleet. Closed loop system also offers the possibility of unloading by pressure, through the drop pipe of the product arm whilst pressurizing the tank via the ‘vapour line’ of the loading arm.
