SUS 304 316 Heat Exchanger Stainless Steel Tube 20ft Length surface finish Annealed & Pickled
CNMAX (MAX STAINLESS STEEL) has pride in providing a whole range of high-class, customizable and innovative ASTM A249,ASTM A213 TP347/347H Stainless Steel Tubes using state-of-art technology.For more than five decades, SPEZILLA has been serving the needs of the oil and gas industries, automotive, shipbuilding, power plants.We place importance not just on managing material sales, but also on ‘before’ and ‘after service’.
High strength, excellent corrosion resistance and minimized carbon content make Alloy 304 and 304L Stainless Steels useful for applications where welding is required. Uses include architectural mouldings and trim, welded components of chemical, textile, paper, pharmaceutical and chemical industry processing equipment.
904L (00Cr20Ni25Mo4.5Cu , UNS N08904)
Boilers, heat exchanger, heaters or condensers.
304,304L, 316, 316L, 321, 310, 310S, 309S
OD from 1/2“ to 4“
Wall Thickness: 0.035“ to 0.109“ (0.9 mm to 2.77 mm)
All tubing is produced with the most advanced Hydrogen Bright Annealing units and weld bead cold working equipment. Only approved raw material suppliers are used that provide uniform wall thickness, Rockwell hardness, strength and elongation. The work cells are equipped with precise roll form tooling, regularly scheduled laser alignment and in-line eddy current testers with automatically programmed cut-out saws. This provides tubes that are produced to the tightest OD, ovality, straightness and length tolerances along with a superior weld condition.
