Lung Shun Fa tube fittings are applied to high pressure, impulse, vibration, vacuum and temperature. The tube fittings has been specifically designed for use on instrumentation, process & control systems and equipment employed in chemical, petroleum, fluid power, electronic and pulp & paper plants.
"LSF" tube fittings, a leak tight seal is achieved through the simple action of tightening the nut against the body. This provides the axial thrust required to compress the captively held ferrules against the O.D. of the tubing. The staged swaging action of the ferrules during the compression phase of make-up provides the key to LSF's sealing superiority.
Stainless steel tube:
1.TP304 and TP316 of ASTM A269 or A213 or equivalent.
2.TP304 and TP316 of JIS G3459 or equivalent.
3.The wall thickness selection should be based on the operating pressure, temperature and shock conditions. Fully annealed tubing is recommended. Stainless steel tubing having a hardness of less than Rockwell B90 should be used.
