Product Description

Tantaloy relief springs are usually used in chlorinators and chlorine feeders, 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 maintains tantalum's excellent corrosion resistance to halogens and acids, even hydrofluoric acid. 

We can custom tantaloy springs according to the spring data, such as

• Material ; 　 　 　
• Wire Diameter;   　
• Outside Diameter; 　 　
• Mean Diameter;  　
• Inside Diameter;　 　
• Free Length;   　
• Effective No. Coils or Active Turns; 　
• Total No. Coils or Full Turns; 　
• Working Length;　 　
• Working force;   　
• Modulus of Torsion(Alternative);　 　
• Ends square and ground;　 　

on request or according to the customer's drawings or blueprint.

Tantaloy relief spring is made of tantaloy "61" metal wire, NRC91(92.5%/7.5% Ta/W) tantalloy wire, which can provide a lifetime warranteed service, the NRC91 tantalloy springs can fully meet the requirements of gas chlorinators for the water and wastewater (the chlorination for the disinfection of water & wastewater) treatment industry 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.
