May I ask about a pilot plant setup: since there are 2 columns, 6 kg of steam is required
Thread Content
I have a pilot plant setup that requires 6 kg of steam to be supplied to 2 columns; these columns have a diameter of 350 mm and a height of around 600 mm. I need to find a manufacturer to produce these components and have them delivered to the site for use in the pilot plant. My questions are: 1. Does the manufacturer need to have a certification for manufacturing pressure vessels? Is it necessary to report anything before taking the processed items away, or are there documents such as a pressure vessel certification required? 2. Once it is brought to the site, does the pressure vessel need to be reported at the factory, or should one go to the **relevant department to make the report? How should this process be carried out correctly?
Pressure vessel manufacturing units must be qualified, and the products leaving the factory must come with a complete set of documentation (including material inspection reports, X-ray images of welds, pre-shipment tests, and so on); legitimate companies will carry out these procedures； Upon arrival at the site, special equipment (pressure vessels) must be reported to the special inspection agency before installation (it is advisable to handle this along with the relevant pressure pipelines as well) ； After providing the necessary information, installation can proceed. Once installation is complete, it is still necessary to go to the special inspection agency for registration; only after that and once everything is in order can it be used.
Do production units need to obtain any certificates related to pressure vessels or similar equipment? Do manufacturers have to register with the local quality supervision agency?
The manufacturing unit must be qualified, and the equipment it produces must fall within the scope of its qualifications. The equipment leaving the factory must come with a certificate of conformity and quality certification documents. For specific details, refer to the \"Safety Technical Inspection Regulations for Fixed Pressure Vessels\".
With this height-to-diameter ratio, it can be considered not a tower. To determine whether it is a pressure vessel, look at the design pressure. If 6 kilograms of steam are introduced, but the operation is at atmospheric pressure. Steam pressure reduction can be considered, along with the use of a safety valve to control the pressure source. Chinese-style equipment is considered as atmospheric-pressure equipment. If it has to be done under pressure, there’s nothing that can be done.
