This is an SS316 tube vessel with a sealed flange and valves that can be used under oxidation, inert, or reduction gas atmosphere up to 600°C for special compounds processing. Such a tube is also suitable for use with MTI tube furnaces to create a system that pressure can reach 15 PSIG. Tube diameter is optional at 25, 38, 50, and 76 mm.Specification: Model Number TSS25D600-316 TSS38D600-316 TSS50D600-316 TSS75D600-316 Outside Diameter: 25 mm 38mm 50 mm 76 mm Inside Diameter: 21 mm 32 mm 44 mm 70 mm Tube Length: 600 mm 600 mm 600mm 600 mm Working Temp. 600°C continuous (without load) Working Pressure 15 PSIG ( 1bar) Installation Thoroughly clean the copper gasket before use Use torque-adjustable wrench to tighten the flange properly Warning: Regularly run visual inspection on the tube surface. The high-pressure vessel is the consumable part, please replace the tube once deformation is noticed. Must install a pressure regulator on the gas cylinder side to regulate pressure. Service-life design for 2,000 hours at 800C. Attention: In order to have a longer tube service life, Please use a quartz or alumina crucible to carry the sample, instead of loading the sample directly inside the tube, please click the picture below to choose one crucible boat:
