904L stainless steel BUTTWELD FITTINGS

UNS N08904 Seamless Fittings, Stainless Steel 904L Pipe Fittings, ASTM A366 SS 904L Butt weld Pipe Fittings, DIN 1.4539 Stub End, ASME SA366 SS 904L Pipe Bend Exporter

For many years, Bhawal Steel Agency has been producing SS 904L buttweld fittings. We provide a variety of SS 904l buttweld fittings, including long radius and elbows, as well as 45 and 90-degree angles. Fittings come in a variety of sizes, ranging from 2 inches to 48 inches in nominal diameter, and are customized to meet the customers' needs.

SS 904L is also known as a popular grade with good corrosion resistance in high-temperature environments. With ASME B16.9 and B16.28 norms, 904L Stainless Steel Buttweld Pipe Fittings fall under the ASTM B366 specification. These standards and specifications call for pipes with nominal bore sizes ranging from 1/8 inch to 48 inches, and they can be ordered seamlessly, welded, or manufactured to meet special needs. The wall thickness and pressure capabilities vary depending on the nominal bore size. Along with custom-built specifications, we offer common sizes, shapes, and dimensions. Different varieties are used for various purposes, such as the Alloy 904L Elbow, which is used to change the direction of a pipeline without putting too much pressure on the walls when welding. The schedules provide the wall thickness and pressure ratings. The schedules vary in length from 5 minutes to 160 minutes and XXS minutes. The types of SS 904L buttweld fittings are ASTM A403 WP904L SS ELBOW LONG RADIUS, ASTM A403 WP904L ELBOW SHORT RADIUS, ASTM A403 WP904L REDUCING ELBOW, ASTM A403 WP904L SS 45 DEGREE ELBOW, ASTM A403 WP904L FABRICATED TEE, ASTM A403 WP904L REDUCER, ASTM A403 WP904L ECCENTRIC REDUCER, ASTM A403 WP904L STUB ENDS, ASTM A403 WP904L TEES, ASTM A403 WP904L END CAP, ASTM A403 WP904L COUPLING, and so on.
