Introduction

 Blind Flange, is also called BL flange. There is no hole in the center, and the function is to close or isolate the pipeline. Mainly used for pipe ends or as heads. Blind flange can be used in an existing operation flow, or for future expansion requirements. It also permits easy access to the interior of a line or vessel, once it has been sealed and must be reopened.

Eathu can supply carbon steel bind flange and stainless steel blind flange.Size range of blind flange:1/2”-24”,customize up to 48”;pressure of blind flange:150LBS/300LBS/400LBS/600LBS/900LBS/1500LBS/2500LBS.The face type:FF,RF,MFM,RTJ,TG.


RTJ blind flange normally use for high pressure occasion which from PN6.3 to PN25.0;RF blind flange normally use for PN0.25 to PN25.0

As the blind flange manufacturers in China,EATHU can also supply OEM flanges according to customers’ drawings or designs.

Welcome to contact Eathu for more information.
