Top loading arms permit the transfer of liquid or liquefied gas from one tank to another through the manhole on the top of a road or rail tanker.
Depending on whether the product is ‘dangerous’ or not, this connection may be open (manhole not sealed), semi-closed (via a cone to the top of the tanker) or closed. A closed connection indicates that the product is dangerous or toxic and made by a flange to the top of the tanker, sometimes equipped with a cone and vapor hose to prevent the vapors from being released into the atmosphere.
When one is top loading, one will have to put operator safety as a number priority as the operator will be on top of the tanker.
Basic Characteristics:
Arm material: carbon steel, stainless steel, aluminium, etc
Custom types: PTFE lined, electric heat tracing, steam jacketed,etc
Nominal diameter: DN50-DN200 (2″-8″)
Design pressure: -0.06Mpa-6.0Mpa
Design temperature: -40°C-100°C
Connection with tanker: open, vapor cone, flanges,etc
Vapor cone seal: PTFE, nitrile rubber, EPDM, etc or other material on request
Swivel joint main seal: PTFE
Balance: compression spring cylinder
