TERMINAL > LOADING
For over 35 years Liquip loading arms have been the benchmark for innovation to those who have used them. Their reduced weight and advanced balance mechanism technology make Liquip loading arms the most maneuverable loading arms available and the loading arms of choice for customers around the world.
"Smooth as velvet, slick as silk"
C&N Petroleum Equipment (PTY) Ltd supplies the Liquip range of laoding arms.
Velvet Touch arms can be customised to suit individual requirements, all with one thing in common...the "VELVET TOUCH".
The name Velvet Touch is a reference to the ease of operation and is the culmination of extensive research into different balancing systems after 35 years in the petroleum equipment manufacturing industry.
It utilises the properties of perhaps one of the best support mechanisms available today and one which is used and well proven in many different applications around the world, the gas spring.
With the gas spring of the Velvet Touch as the backbone of our loading arm range, we manufacture arms for top and bottom loading of petroleum products and chemical applications in a range of sizes and materials.
Specialist arms include low profile gravity unloading arms, LPG loading arms, bitumen arms and vapour recovery arms.
In line with Liquip's dedication to quality, Liquip loading arms and components are made to world standards in accordance with ISO9001 Quality Assurance System.
Liquip use the latest in available design and manufacturing techniques to ensure that our arm designs work to their full potential, giving our customers the best possible solution for their investment, and consistent product quality.
Repeat sales with existing satisfied customers across 27 countries proves that our loading arms continue to provide significant benefits and value for money.
CHEMICAL COMPATIBILITY
Liquip loading arms are available in a range of materials and seals to suit various chemicals and liquids. Liquip reference industry standard chemical compatibility charts when deciding compatibility of materials and physically test product compatibility with seal and gasket material.
If in doubt, consult Liquip and if available provide your recommendations and material safety data sheet for specific products.
THERMAL RELIEF
Over pressuring of the loading arm can be caused by thermal expansion of the product contained in the loading arm pipe work, i.e. the temperature of the static product within the loading arm is higher than the ambient temperature.
This is caused as a result of the sun heating the pipe and product; as the temperature rises so too does the pressure within the loading arm.
This increase in pressure, if severe enough can cause seals and gaskets to rupture and can damage the API coupler. Recommended operating static pressure for loading arms is 1,000 kPa, refer to Liquip Tech Talk T011.
Liquip recommend that you consult your company policy on thermal pressure relief and put in place a system to prevent over-pressurisation through thermal pressure buildup.
FUEL VELOCITY
Loading rates differ between installations. It is always advantageous to maximise loading flow rates in order to minimise loading time.
However ensure that the fuel velocity at any flow rate, does not exceed maximum safe rates.
Excessive velocity increases the generation of dangerous static electricity and should be considered.
It may be wiser to increase the size of the loading arm to achieve the same flow rate, thereby minimising static generation.
ORDERING INFORMATION
To ensure each loading arm that leaves our factory operates to its maximum potential, Liquip requests that the dimensional details and designs of each installation be checked by our design department.
If your requirements are beyond the scope of this catalogue, contact us.
Design survey sheets are available from Liquip and Liquip distributors.
The following is the information needed to recommend an arm to suit your requirements:
To help maximise the productivity of your loading arms and thus provide the best value for money, it is important that Liquip be consulted early in the planning stage of the bulk liquid terminal or loading rack.
The loading arm is the last component of an expensive supply chain so it is important not to compromise this important asset.
