Factory Pressure Test

Factory pressure test is a critical quality inspection procedure before equipment delivery. It is mainly conducted on reaction kettles, tanks, pipelines, and pressure vessels through hydrostatic or pneumatic testing. Specified pressure is applied inside the equipment and maintained for a set period to check for leaks, deformations, or insufficient pressure resistance in welding seams, sealing surfaces, and the overall structure, ensuring safe and stable operation under actual working conditions. The whole process strictly complies with national and industrial standards, with complete pressure data records. Only passing the test can the equipment proceed to the next production stage. This procedure effectively eliminates potential safety hazards, guarantees the sealing performance and structural strength, and provides important assurance for the ex-factory quality of products.
