Audited Supplier Lap joint flange is usually used with a lap-joint & hub. These are useful where temperature, pressure changes, vibrations and shocks are not severe. These flanges are not useful where severe bending stresses exist. These flanges have only about 10% of the fatigue life as compared to welded neck flange. For these flanges bolt holes can be easily aligned and this simplifies the installation of large diameter vessels. These flanges are useful for operations where the vessel is frequently opened up for cleaning and inspection.
Our factory is the first choice of stainless steel flanges and carbon steel flanges to meet your demands. We can provide a series of high-quality pipe flanges, such as din flanges, ansi flange, asme flanges, jis flanges, en flanges, bs flanges, 150# flanges, rjt flanges, raised face flanges, loose flange, flat face flanges, weld neck flanges, slip on flanges, plate flanges, blind flanges, socket weld flanges, orifice flanges, threaded flanges, lap joint flanges, spectacle flanges, spectacle blind, orifice plate, blank, carbon steel flanges, stainless steel flanges, based on guaranteed quality.
Common production as world standards include ASA/ANSI (USA), PN/DIN/EN (European), BS10 (British/Australian), BS4504 (British/Australian) and JIS (Japanese). Our flanges are made by forging or casting according to clients' request and flange faces are flat face (FF), raised face (RF) or ring joint (RJT) styles.
