How to calculate the added value of the boiler vessel steel plate?

Boiler vessel steel plate added value is an important indicator often used in boiler and related industries. It can provide users with a very important reference in practical applications. However, what does the boiler vessel steel plate added value specifically mean, calculate the boiler vessel steel plate?
What is the use of plate added value and how to calculate it? Many people are not too clear. We will explain to you how to calculate the added value of boiler vessel steel plate.

1. According to the type of steel plate, the theoretical weight calculation method of steel plate is different:
For example, the thickness of ordinary medium plate and low alloy steel plate is generally negative deviation, which means that the theoretically calculated weight is generally greater than its actual weight. The boiler vessel steel plate generally has a positive deviation, which means that the thickness of the steel plate is greater than the actual thickness. Generally, this large thickness is called the boiler vessel steel plate thickness added value. Therefore, it is necessary to add its added value when calculating the weight by theory.

2. The calculation standard of the added value of the boiler vessel steel plate varies during use according to actual needs. The old and new standards have the following differences:

Thickness tolerance and weight difference:
(1) Thickness deviation: The new standard allows the lower limit negative deviation of -0.3mm, and the old standard allows the lower limit negative deviation of -0.25mm.
(2) Theoretical weight calculation: The thickness adopted by the new standard theoretical weight is the arithmetic average of the thickness allowed by the steel plate, and the nominal thickness of the steel plate used by the old standard theoretical weight + added thickness.
