Raw Material Selection
The manufacturing process of buttweld fittings begins with the careful selection of raw materials.
Sheetal Industries is a reliable manufacturer, stockist, and distributor of high-quality Super Duplex Steel UNS S32750 Buttweld Fittings. Designated as F53, these fittings possess a distinctive combination of higher strength, along with excellent corrosion resistance, because of their higher content of chromium, molybdenum and nitrogen. Compared to UNS S32760 (F55), UNS S32750 has better overall strength and slightly better performance in chloride-rich environments like seawater and brine. These fittings are especially valued in industries that demand durability and reliability under extreme pressure and corrosive conditions. Their excellent weldability, low-temperature toughness, and high thermal conductivity make them a solid choice for heat exchangers and offshore platforms.
Table Of Content
The fittings are manufactured in line with ASTM A815 / ASME SA815 specifications. The chemical composition includes Chromium (24–26%), Molybdenum (3–5%), Nickel (6–8%), and Nitrogen (0.24–0.32%), with minimal Carbon, Manganese, and Silicon to maintain corrosion resistance. The density of UNS S32750 is 7.8 g/cm³ and the melting point is approximately 1350°C. These characteristics enable the fittings to sustain their form and functionality at high temperature and pressure. Super Duplex Steel S32750 Buttweld Fittings come in various shapes and sizes such as elbows, tees, reducers and crosses each of which is engineered to meet diverse piping needs while providing long service life.
These fittings find extensive application in chemical processing, oil and gas refinery, marine and desalination plant operations. Their resistance to pitting and stress corrosion cracking makes them ideal for applications in underwater pipelines, offshore structures and brackish water applications. All the products go through a regime of testing involving hydrostatic testing, ultrasonic testing, and positive material identification (PMI) to guarantee performance and conformity to international quality standards. Sophisticated forming and welding processes are used in manufacturing to improve structural integrity and accuracy of dimensions.
Each fitting is carefully packed using protective materials like bubble wrap, plastic end caps, and strong wooden crates to prevent damage during shipping. Documentation such as test certificates and product markings is provided with each batch to ensure full traceability.
