ASTM B 862 yog dab tsi?
ASTM B862 yog tus qauv kev qhia tshwj xeeb rau welded titanium thiab titanium alloy yeeb nkab npaj rau kev tiv thaiv corrosion thiab siab kub. Nws yog welded counterpart rau ASTM B861 (seamless yeeb nkab) thiab yog technically sib npaug rau ASME SB-862, ua rau nws haum rau ob leeg muaj thiab siab hlab ntsha code daim ntaub ntawv.
Thaum ASTM B338 npog welded tubing rau condensers thiab tshav kub exchangers (feem ntau me me diameters), ASTM B862 npog welded yeeb nkab-xws li loj diameters mus txog thiab tshaj 24 ntiv NPS-tsim rau piping systems, txheej txheem kab, thiab structural applications.
