Nickel-based alloys are present in a wide range of uses, e.g., chemical industry, offshore desalinization/inverse osmosis, low-cost brackish water heat exchangers, etc. In these nickel alloy applications corrosion resistance and strength are the most critical properties of the material. Often the engineers will refer to the ASTM B165 and ASME SB165 specifications when they are in the market for seamless or welded nickel-copper (Cu-Ni) tubing. These specs introduce the different tube diameters (thin wall, medium wall, instrumentation, heavy-wall, heat exchangers, etc.) that the purchaser can choose from, serve as a point of reference for corrosion resistance, and have a yield/tensile strength of approximately 70 000 psi and thermal conductivity that is fairly good material indicators for the engineers.
One of the midstream procurement platforms e.g., pipingmaterial.sa provides project buyers with options to identify stockists and mills who supply the popular monel 400 tube in outer diameters from 6 mm to 219 mm with cold drawn or annealed conditions for refinery brine service applications. Specification of high performance nickel-chromium-molybdenum alloys is a common practice for highly acidic and oxidizing environments in flue gas scrubbers, pharmaceutical reactors, and multipurpose chemical plants. Material datasheets often reference ASTM B622 or B619 for seamless and welded pipe and tube products including solution annealed conditions with wall thickness tolerances defined by ASME and ISO codes.
Groups involved in procurement working alongside local EPC contractors in Jeddah usually weigh pitting resistance equivalent numbers and weldability prior to the confirmation of alloy selection. On pipingmaterial.sa buyers and project engineers can find nondiscriminatory distributors offering corrosion resistant hastelloy c22 tube in sizes from 1/4 inch instrumentation coils to large heat exchanger tubing along with ASTM compliant certification supporting sour gas processing and chloride rich process streams within Saudi industrial supply networks.
