Made of SUS 316 L grade steel, this Ring Joint flange can endure 5 k to 30 k operating pressure range. Its standard conforms to JIS norms. This type of industrial flange is used for connecting pipelines by welding. Its advanced design promotes effective transfer of stress from weld neck pipe flange to pipelines. As its result, possibility of high stress accumulation minimizes. Provided Ring Joint flange is suitable for high pressure based job. Rigid body, ability to resist high welding temperature, long lasting surface finish and capacity to endure large fluctuation in temperature and pressure are the key aspects of this flange.
