The minimum length of the equipment tube section is 300 mm; is there no specification regarding a maximum length? Is only a minimum length specified, with no requirement for a maximum length? Xiaobai, I have a question – I couldn’t find it in the standards.
It is necessary to understand the origin and principle behind his rules; one cannot simply look for an opposite term just because a rule exists. For reference.
The widest board you can buy is the maximum.
The common plate width in the market is 1500 for stainless steel, and 2000/2200/2500 for carbon steel
The maximum width is the width of the sheet material that can be purchased, and this width depends on the width of the rolling machine; the sheet materials used in chemical equipment are generally a little over 2 meters wide. If you want to ask if there are boards with a greater width? Yes, the panels used on aircraft carrier decks are 4.8 meters long, but chemicals industries don’t require such high-quality panels.
The shortest tube section takes welds and stresses into account!
The maximum length depends on the mode of transport! Items that exceed transportation requirements are shipped in segments.
This post was last edited by zjq1962 on 2021-12-14 08:47 to clarify why a minimum length is required. It’s not specified that a minimum must be set; a maximum also has to be specified! The greater the cylinder width, the fewer circumferential seams there are. However, the cylinder width is determined by manufacturing capabilities, and no standards are set for it.
Sigh, why do the people upstairs always use a critical tone? Everyone has been a beginner at one point. The fact that you can ask this question shows that you are at least thinking about it, and I think that’s great! The standard specifies a minimum shell section length. Primarily, this is done to prevent manufacturers from piecing together numerous scraps and leftover materials. To ensure the quality of the equipment’s welds, various factors such as the heat-affected zone of the welds were taken into account; ultimately, a length limit of 300 mm was established. Understanding the purpose of this length specification naturally makes it clear why there is no limit on the maximum length. It’s like children who are over 1.1 meters tall need to buy tickets when taking the train; do you think it’s necessary to set further limits as well?
The width of steel plates is limited; it’s not possible to have an unlimited length
Due to transportation constraints, if the board is too wide, traffic police will issue a ticket.
