Obtain Class B boiler certificate
Thread Content
Hello everyone! Our company is preparing to obtain a Class B boiler certificate. Currently, while manufacturing the products to be tested (oil boilers), we are facing the following issues: 1. Do the drawings of the products to be tested need to first have the design approval stamp issued by the special inspection agency? 2. When undergoing inspection, is one finished product or one semi-finished product prepared? 3. For a finished product, since it is an oil furnace, is heat-insulating packaging necessary? (After packaging, it’s hard to see clearly the actual product and the water pressure.) 4. Is the water pressure checked when inspecting the finished product? 5. Should I burn it to show them? 6. What should the semi-finished product look like (horizontal oil furnace)? New questions are welcome – let’s work together to find solutions! Thank you all!
1. Approval of the drawing design for the product to be inspected. 2. Produce one finished product and one semi-finished product. 3. Do not package them. 4. Is it necessary to check the water pressure? 5. The department needs to see it burning. 6. Provide one tube sheet and one boiler drum
But we don’t have a Class B manufacturing certificate yet; can the design approval stamp be added to the drawings?
The drawings definitely need to be approved first. After applying for a Class B certificate online, there seems to be a receipt confirming acceptance, and that can be used along with the drawings to submit them for approval
After the application is accepted, an acceptance number will be provided, which can be used to submit the drawings to the provincial special inspection institute for approval. The finished product does not require insulation; the semi-finished products are the main pressure-bearing components, such as furnace tubes and tube sheets. Water pressure is required, but combustion does not. Based on my personal experience. . . .
