1. Application and treatment of radial extrusion pipe making equipment.

　　According to the production process and equipment operation manual and relevant regulations of this industry, the user unit should formulate the processing rules and operating procedures of the radial extrusion limiting pipe machine and strictly implement them.

　　2. Damage and repair of suspension roller shaft.

　　The suspension roller shaft is the main part of the radial extrusion limiting pipe machine, and it is also a vulnerable part. The wear of the whole length is uneven, especially in the cement pipe mold, the contact part of the rolling ring wears faster, and the relative error of other parts on the shaft should not exceed 3mm, otherwise it will seriously affect the qualified rate of the product. There are other protections in these two vulnerable places, but they are not ambitious.
