Loading & Unloading
Solutions
WSI’s range of Gas Loading Arms and Unloading Arms are specifically designed to handle liquefied gases like LNG and LPG. Whether for top or bottom loading or unloading of tank trucks or (Russian) railcars there is a WSI Gas Loading Arm to suit the application. All Gas Loading Arms and Unloading Arms are of modular design with flanged connections of all the major components, thus allowing easy arm configurations and superior maintenance capabilities. The inlet flange connection of our LPG Loading Arms and LNG Loading Arms will suit the application

- MOC: carbon steel, stainless steel or low temperature steelSeal materials Viton, PTFE or Kalrez, depending on the process parameter
- Design pressure: 25bar, higher on request
- Design temperature: -196°C to +80°C for LNG Loading Arms, -40°C to +80°C for LPG Loading Arms
- Gas Loading Arms are available as product and vapour recovery arm
- For bottom loading this can be carried out as Bottom Loading Station, e.g. two Gas Loading Arms (one for liquid and one for vapour) installed on a single standpost.
All WSI Gas Loading Arms are designed and manufactured within our certified ISO quality management systems and in line with ASME 831.3 Process Piping code. All loading arms and swivel joint assemblies are 100% hydro tested. Dye penetrant testing and Radiography carried out to required specifications. Full manufacturing documentation and MTR's can be provided with each Gas Loading Arm. Standard paint finish for carbon steel is shot blasting to SA 2 1/2 and Poly Urethane RAL 7035 paint finish. Specific painting specifications also provided. If required, TPI will be provided
BOTTOM LOADING ARMS
WSI range of bottom loading arms are specifically engineered to handle the unique nature of liquid compressed gasses and vapors transported in tank trucks or railcars, or trans-loaded between the two. Up to #300 rated with minimal flanged connections in carbon steel and stainless steel to handle refined products such as LPG, Propane, Butane, Isobutene, Anhydrous Ammonia, LNG as well as course unrefined NGL's.
Typical size is 2" but larger 3" and 4" are available for specialized applications. For longer reach applications a 3" arm is usually better suited for structural strength with a 2" connection point to the tank truck or railcar.
Connection devises will vary with different applications. Each WSI compressed gas bottom loading arm is designed to work with either, dry-gas couplers and adapters, hammer unions or lap flange connection points. Outboard swivel joints are incorporated in to each bottom loading arm with multiple flow control and connection options. Isolation valves, breakaway devices and remote shut down devices can all be incorporated in to each configuration of bottom loading arm arm.
All bottom loading arms are offered in standard length configurations or custom sized to suit the exact application

DETAILS
The W720 Long Reach (unsupported) bottom loading/unloading arm is ideal for transferring compressed gas liquids and vapors to or from tank trucks or rail cars. The W720’s long reach enables greater flexibility with miss-spotting or obstructions from other rail car and tank truck equipment
The W720’s long reach and signi cant miss-spot capabilities are due to a swivel boom that extends “unsupported” from the riser on the stand post. This provides an extra plane or rotation and allows the loading arm to track a distance along the bottom side of a rail car, or bottom side or rear of a tank truck

TOP UNLOADING ARMS
WSI range of top unloading arms are specifically engineered to handle the unique nature of liquid compressed gasses and vapours transported in tank trucks or railcars, or trans-loaded between the two. Up to #300 rated with minimal flanged connections in carbon steel and stainless steel to handle refined products such as LPG, Propane, Butane, Isobutene, Anhydrous Ammonia, LNG as well as course unrefined NGL's.
Typical size is 2" but larger 3" and 4" are available for specialist applications. For longer reach applications a 3" arm is usually better suited for structural strength with a 2" connection point to the tank truck or railcar. .
Connection devises will vary with different applications. Each WSI compressed gas loading/unloading arm is designed to work with either, dry-gas couplers and adapters, hammer unions or lap flange connection points. Outboard swivel joints are incorporated in to each loading arm with multiple flow control and connection options. Isolation valves, breakaway devices and remote shut down devices can all be incorporated in to each configuration of top or bottom, loading or unloading arm.
All loading/unloading arms are offered in standard length configurations or custom sized to suit the exact application.
All WSI loading arms are designed and manufactured within our certified ISO quality management systems and in line with ASME B31.3 Process Piping code.

DETAILS
W320-H long reach top loading arms are designed speci cally for loading/unloading compressed gas liquids and vapors from and to railcars where miss-spotting is likely i.e. when connecting with a line of coupled varying length railcar tanks. The W320-H’s longer reach and miss-spot capabilities are due to a “swivel boom” that extends “unsupported” from the riser on to which a xed reach loading arm is attached. This provides an extra plane or rotation and allows the loading arm to “track” a considerable distance along the centerline of a railcar.
W320-H has a 2” SS drop hose, 90° Style-30 Outboard swivel joint assembly with an option of a 2” ball valve to allow for orientation on top of the rail car as well as controlling the supply to/from the loading arm.
Outboard connections can be dry-gas coupler, hammer union or lap flange to suit the application. Breakaway couplings, remote shut down devices and purge systems can be incorporated as required.

DETAILS
W420 long reach top loading arms are designed speci cally for loading/unloading compressed gas liquids and vapors from and to railcars where a signi cant miss-spotting capacity is required and additional equipment is to be carried by the arm. i.e. when connecting with a line of coupled varying length railcar tanks and breakaway devices are to be incorporated. The W420’s longer reach and signi cant miss-spot capabilities are due to a “swivel boom” that extends “supported” from the riser on to which a xed reach loading arm is attached. This provides an extra plane or rotation and allows the loading arm to “track” a considerable distance along the centerline of the railcar as well as carry additional weight.

DETAILS
W420-DH long reach, dual connection top loading arms are designed speci cally for loading/unloading compressed gas liquids from and to railcars where signi cant missspotting capacity is required and both liquid connections on the rail car are to be used. The W420-DH’s longer reach and signi cant miss-spot capabilities are due to a “swivel boom” that extends “supported” from the riser on to which a xed reach loading arm is attached. This provides an extra plane or rotation and allows the loading arm to “track” a considerable distance along the centerline of the railcar. Dual drop hoses are attached at the apex swivel joint via a “cross bar” which spreads the dual drop hose assemblies across the width of the manhole so both liquid connections can be orientated and simply connected
W420-H has 2 x 2” SS drop hoses, 2 x 90° Style-30 Outboard swivel joints with an option of a 2 x 2” ball valves to allow for orientation to both liquid connections on top of the rail car as well as controlling the supply to/from the loading arm.
Outboard connections can be dry-gas coupler, hammer union or lap flange to suit the application. Breakaway couplings, remote shut down devices and purge systems can be incorporated as required.

FEATURES
- Typical range of vertical movement is +70° park position to -20° load position
- Made from all carbon steel or stainless steel.
- A separate 2” vapor hose can be “piggy backed” to the loading arm to guide and connect/disconnect both liquid connections as well as the vapor connection at the same time without orientating a separate piece of hose
- Typical boom length is 1,800mm. Primary length is 2,000mm to 2,500mm with a 1,500mm drop hose and Style-30 swivel joint.
