ASTM B366 Hastelloy C22 Pipe Cap
HASTELLOY Alloy C-22 is a nickel-chromium-molybdenum alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. It resists the formation of grain boundary precipitates in the weld-heat affected zone making it suitable for use in the as-welded condition. C-22 has outstanding resistance to both reducing and oxidizing media and because of its resistibility can be used where "upset" conditions are likely to occur. It is proven to possess excellent weldability and high corrosion resistance as consumable filler wires and electrodes. The alloy has proven results as a filler wire in many applications. As filler wire use when other corrosion resistant wires have failed.
Alloy C-22 can easily be cold-worked because of its ductility and cold-forming is the preferred method of forming. More energy is required because the alloy is generally stiffer than austenitic stainless steels. 0.28" thick sheet in the heat-treated at 2050°F, rapid quenched condition, has an average olsen cup depth of 0.49".
Hastelloy C-22 is a great alternative when superaustenitic stainless steels (AL-6XN®, 904L, and 254 SMO®) and duplex stainless steels (2205 and 2507) will not withstand extremely aggressive media. This is because it is a nickel-chromium-molybdenum-tungsten alloy with better overall resistance to uniform and localized corrosion than any other Ni-Cr-Mo alloy, like Hastelloy C-276, C-4, and alloy 625.
The function of a Hastelloy Butt Weld End Cap Fitting is to block off the end of a line in a piping system. The Butt Weld Cap Pipe Fittings is fitted by placing the end cap over the open line and welding around the joint. Meanwhile, our products are can further be made-to-order as per the detailed requirements given by our valuable clienteles.
ASTM B366 Hastelloy C22 Pipe Cap Specifications
1.Size: 1/2" To 120" (DN15-3000)
2.WT: Sch5-Sch160,XS,XXS,STD
3.Standard: ASME, JIS, DIN, ANSI, etc.
Hastelloy C22 is very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications.
