It is the advanced technique in the world to make wind pipe with pin-board type flange. It is capable of making standard and mechanical rectangle flange in batches, compared with traditionally angle iron flange making, it features saving time, saving materials, high effect, fine sealing performance, durable and solid connection. Therefore, it is suitable for making rectangle wind pipe with big section.
