According to "Special Equipment Safety Supervision Regulations":
Article 75 Without authorization, manufacture and installation of boilers, pressure vessels, elevators, hoisting machinery, passenger ropeways, large-scale amusement facilities, special motor vehicles in the field (factory), their safety accessories, and safety protection devices. , Transformation, and manufacturing activities of pressure pipeline components shall be banned by the special equipment safety supervision and management department, and the illegally manufactured products shall be confiscated, and those that have been installed or modified shall be ordered to be restored to the original state or ordered to be reinstalled and modified by the unit that has obtained the license within a time limit. Impose a fine of 100,000 yuan up to 500,000 yuan; if the criminal law is violated, the person in charge and other directly responsible persons shall be responsible for the crime of producing and selling fake and inferior products, the crime of illegal business, the crime of major liability or other crimes in accordance with the Criminal Law. Investigate criminal responsibility according to law.
The license for the manufacture of boiler and pressure vessel steel plates is valid for 4 years. The manufacturing, installation and maintenance unit should inform our company 6 months before the license expires. We will apply for a renewal for your company. A decision to grant or deny permission is made before the expiration of the validity period. If the validity period of the license expires without renewal, it shall not be allowed to continue to engage in related projects such as manufacturing, installation, renovation, and maintenance engineering.
