Stainless Steel Pipes in Pakistan
Where corrosion, contamination or high temperature would destroy carbon steel, stainless steel pipe earns its cost several times over. A. Karimjee & Sons supplies austenitic, duplex and super duplex stainless steel pipes to ASTM A312, A358, A778, A249, A269 and A270 — covering everything from general process lines to sanitary tubing and aggressive chloride service.
