Issues regarding the construction acceptance of skid-mounted equipment
Thread Content
RT: In recent years, compressor equipment has increasingly been installed using the pre-assembled, ready-to-use format. I was wondering if anyone here knows which standard specifies the construction and acceptance requirements for such equipment?
These types of equipment are usually supplied, installed, and commissioned as a complete package; everything is subject to the terms stipulated in the contract. As long as the production conditions are met, that’s sufficient.
The problem is that **there’s a sinister organization called… Supervisors. For them, acceptance means following certain standards, but where do these standards come from?**
In accordance with the contract requirements, the following standards are also referred to: AQ 3002-2005 – Technical requirements for barrier-type explosion-proof portable vehicle fueling (gas) installations; GB T 25358-2010 – Portable rotary oil-free air compressors for use in the petroleum and natural gas industry; GB T 25359-2010 – Integrated portable reciprocating compressors for use in the petroleum and natural gas industry; GB T 31018-2014 – Guidelines for modular design of mobile laboratories; GB T 31982-2015 – Specifications for modular design of mechanical products; HG T 20659-2014 – Technical specifications for the convection section modules of tubular furnaces in the chemical industry; SH T 3134-2002 – Technical specifications for vehicle gas stations equipped with portable fueling installations. “Modular Principle Design Methods and Applications” by Tong Shizhong, Standard Edition, 1st edition, 2000
The connection pipes in skid-mounted equipment are considered pressure pipes, and they must comply with the technical specifications related to the installation of pressure pipes
The pipes connected inside the jack actually do not need to comply with the technical specifications related to the installation of pressure pipes; following the welding procedures is sufficient
Are there any clear regulations on this in the standards or norms?
The regulations specify it; it’s not here with me, but once I find it I’ll send it over
Generally, when buying something, there is a technical agreement, right? It has to be in accordance with the technical agreement
It is definitely necessary; both the supply and scope of work should be in accordance with the technical agreement. However, regulatory issues cannot be avoided even if they are not specified in the technical agreement
