Floating suction assemblies are designed to draw off uncontaminated fuel from just below the surface of liquid storage tanks. The float ensures that water; foreign matter or sediment at the bottom of the tank is not withdrawn with the fuel. A pivot mounted, unsinkable aluminum or Stainless Steel float will provide the buoyancy required to keep the floating suction near the surface of the fluid.
The intake faces downwards and is fitted with a vortex breaker to provide anti-vortex protection and stop ingress of contamination from the bottom of the tank. Floating suctions are custom made to meet individual requirements of each installation. Diameters and lengths or heights of tanks must be provided. For horizontal tanks or tanks in which the height is much greater than the diameter, double arm design assemblies can be supplied.
Model 92021 Automatic Tank Level Gauge is a float actuated tape driven gauge and by means of a digital counter indicates float travel accurately to 1/16 inch. Model 92021 meets all the specifications and recommendations of the American Petroleum Institute in accordance with API Bulletin 2509B.
Model 92302 Liquid Level Indicator is a reliable float actuated level gauging system. It is designed to provide reliable and virtually trouble-free service for installation not requiring accuracies better than ±1 inch.
A rupture disk is a precision relief device designed to rupture at a predetermined pressure and temperature. It is means of providing protection for personnel and equipment. As such, it must be a safe device. Rupture disks are used where instantaneous and full opening of a pressure relief device is required. These devices are also utilized where “zero” leakage is required of a relief device. These devices can also be used in series as “quick opening” valves.
No dead space
Systems are designed to avoid dead space, improve cleanliness and avoid contamination.
Spring-to-close hand wheel
The actuators such as the Magic Hand Wheel provide an accurate flow and an intuitive use.
Many accessories and options
The quick connection and accessory interchangeability provide a customised solution to meet your needs.
What Is Corrosion Monitoring?
Corrosion monitoring can be described as "The regular measurement of corrosion or corrosivity as it effects an asset". It is most often used to make comparisons between actual and predicted corrosion rates, or for the evaluation of measures taken in prevention or mitigation. Some but not all corrosion monitors are sensitive to erosion that may occur in process plants due to high flow rates and entrained solids.
The asset may equally be a pipeline, a concrete bridge, a large HVAC system in a building, an offshore oil & gas facility or a printed circuit in a computer. When that part of the asset that is of interest is inaccessible, simple methods such as visual inspection or manual measurement cannot be used and special techniques must be introduced. This is especially true of continuous processes where internal corrosion may advance at a rapid rate and lead to catastrophic failure long before traditional "inspection" can detect it. Corrosion Monitoring has therefore, come to be associated mainly with internal corrosion of process equipment, although there are a wide range of other applications where the techniques can do valuable work.
Corrosion is not an isolated phenomenon; it is a natural process that attacks any material, particularly metals, under the right conditions. It is therefore prudent to expect corrosion; to look for it and to be prepared to prevent it once a tendency to corrode is discovered.
However carefully a process plant is designed and the materials of construction selected the risk of corrosion is only reduced. Experience tells us, often with horrific consequences, that it is never eliminated. Failures due to corrosion can be costly to repair, costly in terms of lost or contaminated product, costly in terms of pollution and environmental damage (which in turn may result in fines or closure of the installation), and ultimately it may be costly in terms of human safety.
Fear of corrosion can result in over-design or selection of materials which are not otherwise ideal. By adding to capital cost this may make projects commercially unattractive or unfeasible, so that ultra-safe design alone is not a correct response. Many projects are designed with corrosion allowances in the calculations and monitoring in place to evaluate actual corrosion rates against those predicted, allowing action in good time if a variance is observed. In addition to this valuable service, corrosion monitoring can be used as a pro-active tool to assist with operating the plant in a more effective way, thereby prolonging life and gaining optimum throughput. For example, in the oil & gas industry the produced hydrocarbon liquids or gas and associated water are to some degree variable in composition, temperature, pressure and flow rate. This causes complex corrosion and erosion problems in the production process equipment that are often episodic in nature.
Most operators seek to solve these problems by using some form of chemical treatment in conjunction with careful materials selection. In each case a fine balance must be found between the cost of treatment, the rate of plant deterioration and the rate of production if the business objective is to be met. Corrosion Monitoring is a key tool for this, advising when to treat and what the corrosion rate will be in any given mode of operation. This is information that can drive a continuous improvement process.
Corrosion monitoring methods
In order to incorporate corrosion monitoring into a strategy it is necessary to understand the basics of CORROSION MONITORING METHODS and the tools available. The range of available monitoring methods is wide, but they fall into three main groups: -
