Material selection has a major influence on the final system reliability and life cycle cost in high operating industries. In the majority of cases, cobalt-based alloys such as Hastelloy C276 Flanges are used to line the pipelines through which chlorides, sour gas, and high temperatures flow. Nickel chromium molybdenum flanges in UNS N10276 that comply with ASTM B564 and ASME B16.5 or B16.47 standards will resist corrosion very well, both by pitting and stress. The sizes available usually range from 1/2 inch to 48 inches in diameter, covering pressure classes 150 to 2500.
Several projects in Dammam and Jubail involved the purchase of weld neck, blind, and ring type joint variations, which came with good quality control documentation and traceability. The same goes for marine and desalination equipment, where the corrosion of seawater is the main factor. In this case, Copper Nickel Flanges in alloys like UNS C70600 and C71500 are very effective in resisting biofouling and erosion. Along with ASME B16.5, these flanges are made according to the dimensions laid down therein and are available in both raised face and flat face versions depending on the needs of heat exchangers and offshore piping.
Customers who are located in Riyadh, for example, often consider hydrostatic testing, PMI, and third party certifications as their top priorities. pipingmaterial.sa is a B2B platform that assists two verified parties, the supplier and the end user, in finding each other for the technically correct flange requests in Saudi Arabia. It is a virtual showroom that allows users to make detailed cross-reference specifications before placing the order, resulting in minimal risk exposure in oil and gas and power applications. The dependable source channels help to boost the efficiency of the project schedule and the level of the quality assurance in the regional industrial development.
