High score, high score, about the non destructive testing of pressure vessels in the new capacity sp

TOFD: I've only seen relevant introductions and live demonstrations (buy equipment, they say that the on-site practice of the national exam is in them) Because I don't do flaw detection, I don't know much about it Now, there are study classes in Beijing, and as far as I know, at least five sessions have been held, but ah, the pass rate has been low recently, 50 to 60, and you can check it through the Internet.

Ultrasonic is difficult to inspect welds with a thickness of less than 10 mm. As long as the thickness is more than 10mm, the inspection is possible.

Hello, I am talking about the annual inspection of pressure vessels, there are no qualification requirements for professionals in this use unit, and it is generally the personnel who use the unit tube pressure vessel (boiler pressure vessel pressure pipeline safety management) to conduct inspection, and he can inspect it, ** You can follow the content of the "Pressure Vessel Annual Inspection Report" in the "Pressure Vessel Annual Inspection Report" in the "Pressure Vessel Periodic Inspection Rules". If your unit's funds are not a problem, you can also find a special equipment inspection center.

JB T4730-94 has been replaced by JB T4730-2005, and now the non-destructive testing of pressure vessels is carried out in accordance with JB T4730-2005 "Non-destructive Testing of Pressure Vessels".

JB T non-destructive testing of pressure equipment.

Instead of JB 4730-1994

Although I am not the god of pressure vessels, as a passer-by, I would like to extend my most sincere wishes, I hope you will receive a satisfactory answer as soon as possible, but if there is no satisfactory answer, it is also a perfect choice to adopt me, and the reward of 200 is also put, and I am short of 285 to buy a key ring Thank you.

It is a pleasure to be able to ** this topic with you.

I can only say one aspect of inspection: non-destructive testing:

There are 13 methods, which can be referred to NB T 47013.

Hello, there is no requirement that the self-inspection needs to have two special equipment management personnel.

The annual inspection of pressure vessels is an external inspection, how to implement the system, whether to measure the wall thickness of the vessel, and the wall thickness is a matter of inspection.

Make inspections and inspections clear.

Hello! We'll be happy to answer for you. New Capacity Requirements:

The pipe flange of pressure vessels containing liquefied petroleum gas, extremely and highly hazardous media with a degree of toxicity and strong permeability and moderate hazard media shall be at least a high-neck butt welding flange in accordance with the provisions of the industry standard HG20592 HG20635 series standard. (Note that at least applied).

Apparently not contradictory. Thank you.

It is recommended that you take a look at the "Regulations for the Safety and Technical Supervision of Pressure Vessels" (the new version is called the "Regulations for the Safety and Technical Supervision of Fixed Pressure Vessels") and the "Regulations on the Safety and Technical Supervision of Special Equipment". If you are troublesome, you can directly ask the local area (boiler and pressure vessel inspection institute).

1.Inspections are required.

2.The in-service inspection of pressure vessels is divided into two types: annual inspection and regular inspection. The annual inspection is conducted once a year and can be carried out by the user unit itself or entrusted by an inspection agency.

Periodic inspections must be carried out by an inspection agency, generally once every 6 years. However, the first periodic inspection should be carried out in the third year after the pressure vessel is put into use.

The requirements for annual inspection are described in Article 115 of the Regulations for Safety and Technical Supervision of Fixed Pressure Vessels. Periodic inspection requirements can be found in the periodic inspection section of the procedure. For specific matters, please refer to the "Rules for Periodic Inspection of Pressure Vessels".

Look at the regulations, there's a rule there.
