What is duplex ball valve?
What is duplex ball valve?
Duplex Ball Valve. Duplex ball valves are used for on/off control without pressure drop, and ideal for quick shut-off since a 90deg turn offers complete shut-off angle, compared to multiple turns required on most manual valves.
How strong is duplex stainless steel?
For example, a Type 304 stainless steel has a 0.2% proof strength in the region of 280 N/mm2, a 22%Cr duplex stainless steel a minimum 0.2% proof strength of some 450 N/mm2 and a superduplex grade a minimum of 550 N/mm2.
What is duplex stainless steel used for?
Duplex stainless steel, famous for its excellent combination of good mechanical properties and high corrosion resistance, is widely used in the industrial fields, such as the production of seawater heat exchangers and the chemical containers for use in the high-concentration chloride environments.
What is hyper duplex stainless steel?
Hyper-duplex stainless steel (HDSS) is a new type of duplex steel that offers pitting resistance numbers (PRE) higher than 48. Within the modern duplex family, these duplex stain- less steels exhibit both the highest levels of corrosion pitting resistance as well as mechanical strength.
What grade is super duplex?
Our duplex steel grades 2507 and 4501 are regarded as super duplex stainless steel grades. They are highly alloyed and have a corrosion resistance comparable to high performance austenitics like 254 SMO®.
What is super duplex pipe?
Super Duplex Pipe is a category of duplex pipes. Duplex is a material that has the features of ferritic steel and of the austenitic steel. So this material possesses high strength from the ferritic structure and high corrosion resistance from the austenitic structure.
Is super duplex stainless steel?
SuperDuplex stainless like Duplex, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades.
Is duplex a super alloy?
Alloy Designations Due to excellent corrosion resistance and high strength, the most widely used duplex stainless steel is 2205. The name 2205 comes from a typical composition of 22% Chromium and 5% Nickel. UR52N+ is a popular “super duplex” grade that has high strength and exceptional corrosion resistance.
What grade is super duplex stainless steel?
What are the benefits of super duplex stainless steel ball valves?
For instance, as compared to regularly used carbon steels or stainless steel grades the Super Duplex Stainless Steel Ball Valves have increased tensile strength, superior corrosion resistance properties and have the ability to withstand elevated temperature settings.
What is super duplex stainless steel made of?
Made of a 50/50 mixed microstructure of austenitic and ferrite, super duplex stainless steel is much stronger than austenitic and ferritic steel grades that have similar corrosion resistant properties. This increased strength is caused by the augmented chrome and nickel content in their composition.
What is a super duplex needle valve?
The closing mechanism of a Super Duplex Needle Valves is a disk which is able to rotate. Frequently referred to as a sluice valve, Super Duplex Hydraulic Valves are a kind of fitting which could be opened by lifting a barrier out of the pathway of the flow of media. Os-Lok is your superior alternative to Swagelok & Parker A-lok .
What are the advantages of high alloy valves?
Lastly, these high-alloy valves are advantageous when the Pitting Resistance Number (PREN) is required. Super duplex, used in exotic alloy valves, is a common name for a wide range of materials.
