Manufacturing & Quality
Hot forming or cold forming process, continuous heat treatment, precision machining. Concentric reducers feature centerline alignment for vertical pipe diameter changes ensuring central flow. Eccentric reducers feature one flat side, ideal for horizontal pipelines and pump inlets to prevent air pocket formation. 100% NDT testing including UT ultrasonic and MT magnetic particle inspection. Certified with ISO 9001:2015, CE (PED/CPR), API 5L/6D.
Applications
Widely used in oil & gas transmission pipelines, petrochemical process piping, power plant systems, municipal water treatment, shipbuilding, and industrial HVAC. For pump inlet installations, eccentric reducers should be installed with the flat side facing upward to prevent air accumulation. Monthly capacity of 50 containers with 7-15 days standard delivery. Custom size ratios and special materials available upon request.
