Both are austenitic stainless steels. Grade 304 contains roughly 18–20% chromium and 8–11% nickel and suits general corrosion resistance. Grade 316 adds about 2–3% molybdenum, which gives much better resistance to chlorides and pitting, so it is preferred for marine, coastal, chemical and process environments. 316 costs more than 304. Read the 304 vs 316 article.
Seamless tubes are made from a solid billet pierced and drawn or rolled to size, so they have no weld seam. Welded tubes are formed from strip or plate and welded longitudinally, then usually annealed and sized. Seamless tube is typically chosen for higher pressure and critical boiler or heat-exchanger duty; welded tube is economical for general, structural and architectural use. See the seamless vs welded article.
ASTM A213 covers seamless ferritic and austenitic alloy-steel boiler, superheater and heat-exchanger tubes. ASTM A249 covers welded austenitic steel boiler, superheater, heat-exchanger and condenser tubes. ASTM A269 covers seamless and welded austenitic stainless steel tubing for general service. ASTM A312 covers seamless, welded and heavily cold-worked austenitic stainless steel pipe. See the standards explained.
They are stainless steel shields fitted over boiler tubes, especially at bends and in zones exposed to erosive flue gas. They take the wear in place of the pressure-part tube, so worn shields can be replaced instead of the tube. Ruby Infra Projects makes bend shields, half round tube shields and protective sleeves in every grade for thermal power stations. See boiler tube protection shields, half round tube shields and the boiler spares article.
