In highly demanding process industries, choosing an alloy is hardly a matter of preference but more a question of which material performs better under the given conditions. The Inconel 718 Tube specification is a classic example of a story that goes beyond stainless steel performance capabilities to deliver strength to the highest temperature and stress conditions. Manufactured under the guidelines of ASTM B163, ASTM B167, and ASTM B444, these tubes come both in seamless and welded, usually from 6 mm to 219 mm OD with schedules compatible with ASME B36.19.

The strength of the nickel-chromium base alloy, which is reinforced with niobium and molybdenum, not only confers to the alloy excellent resistance to fatigue but also makes it stable over 650°C. Hence its application to heat exchangers, pressure vessels, and subsea assemblies that have been deployed in the projects of Riyadh and Dammam. When it comes to combining nickel alloys with other piping materials, compatibility of the materials is the core issue. Design teams will normally consider aspects such as thermal expansion coefficient, galvanic corrosion potential, and design pressures consistent with ASME Section VIII and API standards. In the case of a changeover to high-strength stainless and duplex pipelines, the use of forged parts made to the specifications of ASME B16.5 or B16.47 is the norm.

These are usually available in pressure classes 150 to 2500, and the grades selected from ASTM A182 F51, F53, or F55 are those that meet the conditions of chloride environments of the kind found in Jubail chemical plants. Under offshore and sour environments, Duplex Flanges are recognized for their two-phase microstructure which not only brings about a higher yield strength but also provides an enhanced resistance to pitting and stress corrosion cracking. Through pipingmaterial.sa, confirmed purchasers and suppliers within the length and breadth of Saudi Arabia can communicate and obtain in-stock certified components with EN 10204 3.1 certification and inspection through compliance.
