我公司生產(chǎn)的氯甲院專用加料管，已經(jīng)申請國家專利。其特點在于襯層采用特殊工藝成型的PFA材料，內管脹接，外管膠接加固定銷固定，所有法蘭接口均采用整體模壓成型。由于是同種襯層PFA材料，所有焊縫的焊接完全融合成一體。避免了焊縫在高溫和高氣流震動的情況下開裂和產(chǎn)生泄器的危險。該PFA加料管可以在200°c高溫長時間運行，具有耐強腐蝕和強滲透的特點。

The special feeding pipe for Chloromethane reactor produced by our company is our patent product. Its characteristic is that the lining layer is made of PFA material formed by a special process, the inner tube by expanded, the outer tube by glued and fixed with a fixed pin, and all flange interfaces are integrally molded. Due to the same lining PFA material, all welding seams are completely integrated into one. The danger of cracking and leakage of the weld under the conditions of high temperature and high air flow vibration is avoided. The PFA feeding tube can be operated at a high temperature of 200 °C for a long time, and has the characteristics of strong corrosion resistance and strong penetration resistance.
