An ISO 9001:2015 Certified Company,Cromwell Distribution is a leading Stockist of industrial forged flanges (A-182, ANSI B16.5) and plate flanges (A-240, ANSI B16.5) . The flanges are Stockistsin a range of pressure ratings to meet customer specifications. Slip-On flange, Weld-Neck flange and Lap-Joint Flange are three of the most popular types of flanges by us, with Threaded flange and Blind Flange also supplied to order.
We specialise in stockists a comprehensive range of carbon steel flanges,alloy steel flanges and stainless steel flanges from ½”NB to 48”NB. Steel flanges are widely used as connectors in piping systems to connect pipes to pipes, tees, reducers, elbows, valves and other piping equipments.
Other special large diameter flanges can also be supplied on customer demand. We stock many standard size large diameter slip-on flanges, blind flanges and weld neck flanges in 304/304L, 316/316L and also A-105 – carbon steel. Steel flanges are widely used in various industries including power generation, oil and gas transportation, petrochemical plants, refineries, waste water treatment plants, marine and pharmaceuticals plants among others. We can offer carbon steel and alloy steel flanges with electro-galvanized coating and blackodising finish. Our flange products are supplied with EN 10204 3.1 Test Certification, with complete details on the chemical and physical properties of the materials. They are permanently marked with size, schedule, grade, and heat code.
A flange is type of fitting used to connect pipes, valves, pumps and other equipment to form a piping system. A flanged joint involves three separate components; the flanges, the gaskets, and the bolting. One of the most important advantage of using a flange is that it allows more flexibility in maintenance.
