Special Letter from the Quality Inspection Office Regarding Issues with Steam, Water, and Oil Cylinders
Thread Content
In accordance with the notice issued in Special Circular No. 2017(1336) by the Quality Inspection Office regarding opinions on matters related to the safety supervision of pressure-bearing special equipment, must all steam (oil, water) cylinders be subject to inspection and supervision going forward? If inspection is required, how should it be classified? ? ?
Is manufacturing inspection related to classification?
Please carefully understand the meaning of the text following the marks you make
Those smaller than 30L or 150mm are registered and inspected along with the boiler itself, without classification； Those with a capacity of 30L or more, or 150mm or more, can be registered and classified either in conjunction with the boiler or in accordance with TSG 21.
Should the tolerance inspection be specified on the drawing? ? ?
Values greater than 30L fall outside the scope of the regulatory specifications; the heat transfer oil has not reached its boiling point
The drawings certainly need to be clearly written. Lack of classification does not mean that manufacturing supervision and inspection are not required.
Lack of classification does not mean that manufacturing supervision and inspection are not required. Where does it come from? All unclassified containers do not require supervision and inspection. The scope of containers defined by the Special Equipment Law is consistent with that defined by the Containers Act. Only containers required for inspection as specified in the fixed capacity regulations are inspected. In other words, only containers that have been classified are subject to inspection.
So how should we understand this document issued by the General Administration of Quality Supervision, Inspection and Quarantine? ? ?
Which containers require inspection and monitoring shall be determined in strict accordance with the requirements of the Solid Waste Container Regulations. Article 1.3 of the Fixed Volume Gauge constitutes a special provision within the scope applicable to Article 1.4. Only those that fall under category 1.3 but not category 1.4 are subject to inspection. It falls under 1.4.2 and does not include requirements for surveillance inspection. Take a close look at Document No. 1336. Inspection is only carried out for those under the jurisdiction of the fixed capacity regulations. If it is less than 30L or has an inner diameter of less than 150mm, no inspection is required, as it meets the requirements of the Solid Waste Regulations. Document No. 1336 requires handling in accordance with the solid capacity regulations. Only by handling it in accordance with the fixed-volume regulations can it conform to the spirit of Document No. 1336.
