Pressure test manifold: JYGH-105 test manifold is a matched assembly for hydraulic test and is a necessary equipment to achieve control of pressure .
1. Main technology specification Working pressure : 105MPa Working medium:Water & oil Working temp:-29°C thru 121°C Nominal bore: Main bore: φ25mm (1″ ) Side bore: φ25mm (1″ ) Connection type: Union Material class: EE Product specification level: PSL3
2. Structure statement The material of the manifold should conform to therequirement of API Spec 16C and NACE MR0175. The manifold consists of manual plate gate valve ,hydraulic plate gate valve. cross, tee, flange and unionetc
3. Maintenance Cad base grease will fulfill thrust bearing and be checked of consumption and added up without delay,if go bad or polluted, it should be replaced. Check valve chamber and grease monthly ,timelysupplement to ensure lubrication between valve gate and valve seat and sealing reliability. Stem thread should be injected with grease. If valve stem has leakage. grease can be injectedthrough the injection valve in the bonnet.If not applicable. the stem pack should be replaced . Out of usage, the assembly should be cleaned upand inspected. especially for plate valve,the valve gate. bonnet, valve seat and valve chamber should be cleaned up. heavily abrasive part should be repaired and replaced, the grease inside valve chamber should be replaced and re-filled .
