Pressure Vessel Steel Plate

What Is Vessel Plate?

Pressure vessel plate is a steel plate used to manufacture steam boilers, pressure vessels and other pressure vessel structural parts. This kind of steel plate is subject to certain air pressure and water pressure, as well as different temperature environments, such as high, medium and low temperature, so the requirements for this kind of steel plate are stricter.

Product Description

It includes carbon steel, carbon-manganese steel, micro-alloy steel, low-alloy high-strength steel and low-temperature steel. The working temperature is generally between -20°C and 500°C, and can reach 560°C in some cases.

Definition: In addition to requiring certain strength and toughness, the material is also required to be uniform and harmful defects are strictly limited.

Type: According to the composition, it can be divided into two categories: carbon steel plate and alloy steel plate; according to the strength, it can be divided into high, medium and low voltage steel plates; according to the use environment, it can be divided into high, medium and low temperature steel plates and corrosion-resistant steel plates.

What Are The Classifications Of Boiler Plate Steel?

1. In terms of materials, boiler steel plates can be divided into two categories: special carbon steel plates and low alloy heat-resistant steel plates;

2. According to different working conditions, boiler plates can be divided into two categories: steel plates for manufacturing room temperature and medium-temperature pressure-bearing parts and steel plates for manufacturing high-temperature pressure-bearing parts.

Boiler quality plates for room temperature and medium temperature (below creep temperature) are mostly made of carbon steel, including carbon steel, carbon manganese steel, carbon manganese silicon steel, etc., which are mainly used to manufacture boiler drums, header end covers below medium temperature and other pressure-bearing part.

Main Characteristics Of Steel Plates For Boilers

Since boiler steel plate is an important product for important purposes, with strict safety and reliability requirements and high manufacturing technical difficulties, the material must have the following main characteristics:

boiler steel plate in a certain temperature range (in the normal temperature and high temperature) with high yield strength properties;

steel boiler plate has sufficient toughness, manufacturing or use of brittle damage will not occur;

pressure vessel plate has a small strain aging sensitivity, especially in the corresponding working temperature region, to ensure a certain value of aging impact work;

pressure vessel steel plate has a low notch sensitivity, can prevent the steel in the welding, open hole, local stress concentration region to produce cracks;

pressure vessel plate material has good welding performance;

vessel steel plate has good welding performance;

A: It includes carbon steel, carbon-manganese steel, micro-alloy steel, low-alloy high-strength steel and low-temperature steel.

Q: What are the implementation standards for boiler plate?

A: GB/T, EN, ASTM/ASME, JIS, etc

Q: What are the delivery statuses of steel plates for pressure vessels?

A: There are four main delivery states of container plates, namely quenching, normalizing, annealing and tempering.

Q: What are the application ranges of boiler steel plates?

A: Widely used in petroleum, chemical industry, power stations, boilers and other boiler container industries, used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas Bottles, high-pressure water pipes of hydropower stations, turbine casings and other equipment and components.

Q: Dimensions, shapes, weights and allowable deviations of boiler steel plates

A: The size, shape and permission of the national standard steel plate should comply with the deviation regulations of GB/T709--2006; according to the requirements of customer Party A and through agreement between the supplier and the buyer, container steel plates with stricter deviations can be supplied; the steel plates are delivered according to the theoretical weight, and the theoretical calculation The thickness adopted is the arithmetic mean of the maximum and minimum allowable thickness of the steel plate, and the density of the steel plate used in the calculation is 7.85g/cm3. Generally speaking, the density of container plates, low alloy plates, high-strength plates, etc. should be calculated according to 7.85g/cm3.

Q: What are the characteristics of container steel plates?

A: Since the boiler steel plate works under medium temperature (below 350°C) and high pressure, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and gas corrosion. It is required to ensure a certain strength and have good welding and cold bending properties. It has a very special composition and many excellent properties. In the current market, this kind of container plate is mainly used to make pressure vessels. For different situations and different uses, the corresponding materials should be different.
