The stainless steel grooved fittings are manufactured and tested according to (CJ/T 152-2010）,
materials are available to stainless steel 304L ,stainless steel 316L .the grooved fitting is mainly
composed of three parts sizes：seal rubber ring, clamp and lock bolt ,size from 32mm up to
323mm with max working pressure is 4Mpa 。
*Material performance superiority .
*Advantages of environmental protection
*Easy opration
*Cost-effective superiority
*Quick connection and safe installations
*Remarkable corrosion resistance
*Superior crush resistance
TECHNICAL DATA
The last manufacturing process of stainless steel grooved fittings can be annealed ，polished and sandblasted ,
also all the groobed fittings absolutely are passed leakage test ,
