Industrial equipment assembly normally depends on standardized mechanical parts that are expected to transfer loads in a predictable manner and that have a certain service life. In manufacturing and EPC projects, it is generally the case that when ordering from a fasteners manufacturer in India to supply the UAE, standards such as ASTM A193, A194, ISO 898, and DIN 931 for bolts, nuts, studs, and screws are referred to. Production usually includes both metric and inch sizes ranging from M8 to M64, tensile classes from 4.6 to 12.9, and materials like carbon steel, alloy steel, and austenitic stainless steels.
Different process choices lead to different performance qualities, with cold forging being a method for making high-volume hex fasteners, whilst hot forging is a method briefly describing the production of large diameter studs. Heat treatment procedures such as quenching and tempering specify the product's hardness and yield strength whereas different types of coatings like zinc flake, hot dip galvanizing, and Xylan are only a few examples from a long list of possibilities that will reduce corrosion. Dimensional inspection, ultrasonic testing, and chemical analysis are just some of the tests that are routinely performed in order to keep the tolerances that are used for the power generation, mining, and heavy machinery industries. Having traceability through heat numbers and mill test certificates, the manufacturer or supplier is able to demonstrate its compliancy during third party audits.
Fasteners are in direct contact with pressure retaining components and the accuracy of preload will determine a good gasket seating and vibration performance. Engineering calculations are done for determining the bolt circle diameter, flange thickness, and operating temperature so as to prevent leakage or fatigue failure of the pipe system used for carrying steam, hydrocarbons, or chemicals. To these joints, a procurement that is done by reference often to a Flange Manufacturer in India serving Italy for ASME B16.5 and EN 1092-1 slip-on, weld neck, and blind flanges is the natural step. These are made in ASTM A105, A182 F316, and pressure classes 150 to 900 and they can be used everywhere for cross-border industrial projects worldwide.
