Tantaloy springs or Tantalloy springs, made of NRC® 91 Metal wire, are primarily used in gas chlorinator (chlorination system or chlorine gas feeder), its H.S. code 8421 99 90 00 or 8421 99 00 91 of filtering or purifying machinery and apparatus for liquids or gases, it is available for tantalloy inlet spring, tantalloy relief spring, tantalloy ejector spring, tantalloy compression spring, tantalloy ejector check valve spring, Vacuum regulator inlet spring, safety valve spring, etc., for their superior tensile and yield strengths and torsion modulus. These properties are retained at high temperatures in vacuum. Furthermore, this tantalum alloy has good dimensional stability even after repeated thermal cycles to 2400°F(1315 °C) in vacuum. This tantalum alloy spring maintains tantalum's excellent corrosion resistance to halogens and acids, even hydrofluoric acid contributing to its unique features(Both RoHS compliant and the following ROHS):
- Remarkable dimensional stability even when thermally cycled to 2400 °F(1315 °C) in vacuum.
- Outstanding corrosion resistance to chlorine, bromine and inorganic acids (except for HF - hydrofluoric acid);
- High strength and " springiness" or excellent resilience which are retained at high temperatures under vacuum;
- Superior toughness + stiffness, high-temperature mechanical properties and high density.

------What is the Gas Chlorinators?----------------------
Chlorinators are devices used to inject chlorine into water. They are used to add chlorine to water for the purpose of disinfection. Chlorinators can also be used to add chlorine to sewage to destroy bacteria and eliminate odors.
Chlorinators are said to be fairly simple to operate. Easy operation, combined with chlorine's ability to destroy bacteria within a desirable time period, makes chlorinators popular for a number of applications. Furthermore, chlorine offers long-term protection against certain bacteria and is fairly low in cost.
Gas Chlorinators are widely used in the Municipal And Industrial Water Treatment such as :
Drinking Water - disinfection of potable water; taste and odor control; iron & manganese precipitation; Hydrogen Sulphide removal.
Industrial Process Water - food processing; poultry processing; canning and bottling.
Chilling Water - meat, fish & poultry processing; canning.
Washdown Water - food processing; poultry processing; dairies; canning & bottling.
Cooling Tower Systems - algae & slime control; Legionnaire's disease control.
Drip Irrigation Systems - eliminate slime & algae deposits.
Citrus Packing - citrus canker destruction; washing.
Fruit & Vegetable Processing - increase shelf life; washing.
Poultry Processing - hand washers; eviscerating line; bacteria reduction; chilling water; increases shelf life.
community, hotel & motel, country club, schools; disinfection & algae control. Chlorinators are often used in swimming pools. Swimming pools can harbor dangerous pathogens that thrive in the water and have the ability to threaten the health of swimmers. Sometimes, bacteria found in swimming pools can cause rashes or illnesses. Chlorinators can be used to rid swimming pools of these often invisible, but still hazardous pathogens. Though chlorine is capable of destroying certain harmful substances, its use in recreational pools is generally not harmful to humans. However, too much chlorine can be irritating to the eyes and skin. An overabundance of chlorine in a swimming pool can also cause harsh vapors. Therefore, it is important to choose a good chlorinator model, capable of effectively regulating the amount of chlorine in the water.
In addition to keeping swimming pools clean, chlorinators have another helpful purpose. They work to reduce the amount of labor required for pool maintenance. With many types of chlorinators, the amount of chlorine in the water need only be checked on a weekly basis. Most have automatic gauges that indicate whether or not more chlorine is needed. Such gauges also indicate when the water has too much chlorine.
Sanitary Sewage - effluent disinfection; pre-chlorination; odor control; reduce Biochemical Oxidation Demand (BOD); control filter ponding.
Package Treatment Plants
Process Wastewater - disinfection; odor control; up-sewer chlorination.
Plant Wastewater - cyanide destruction.
Color Removal - dye waste treatment.
Chlorinators with automatic gauges make adjusting chlorine levels easy. Many allow the user to change chlorine levels with a simple twist of a dial. With such easy adjustment, pool owners can spend more time enjoying their pools and much less time on pool maintenance.
Thought most people don’t have to worry about disinfecting their own drinking water, there are some locations in which homeowners find it necessary to do so. In such places, chlorinators can be used to make water safe for human consumption. Often, these chlorinators are part of in-house treatment systems, along with softeners and filters.
Operation way of Vacuum System for gas chlorinator :
Water flowing through the ejector venturi, creates a vacuum which opens the check valve in the ejector. The vacuum is carried through the vacuum line to the vacuum regulator where the pressure differential created causes the inlet valve at the vacuum regulator to open, initiating gas flow. A spring opposed diaphragm in the vacuum regulator, regulates the vacuum. The gas passes under vacuum through the flowmeter, the rate control valve, the vacuum line and to the ejector.
The system is completely under vacuum from each ejector to the vacuum regulator inlet safety valve. If the water supply to any ejector stops or vacuum is lost for any other reason, the spring loaded inlet valve immediately closes and isolates the gas supply. If the gas source is depleted, the unit seals to prevent moisture from being drawn back into the gas source.
When more than one feed point is desired multiple flowmeters and ejectors can be supplied.
