Structural performance and advantages of stainless steel reactors

In fields such as petroleum and chemical engineering, reactors serve as pressure vessels that complete processes like vulcanization, nitration, hydrogenation, hydrocarbonization, and polymerization, playing an important role in providing a physical or chemical reaction environment. Depending on the usage scenario, the materials of the reactors vary, with commonly used materials including stainless steel, carbon manganese steel, zirconium, nickel-based alloys, and other composite materials, among which stainless steel reactors are the most common.

Difference between stainless steel reactors and enamel reactors

With the development of technology, both food and chemical industries require various reactions, leading to a diverse range of reaction kettle types. However, the commonly used reaction kettles are still stainless steel reaction kettles and glass-lined reaction kettles. Below, we will introduce the differences between the two types of reaction kettles.

Welding between mechanical equipment components of pressure vessels

Due to the characteristics of pressure vessels and the chemical process properties of the internal media, it is often necessary to set up safety devices and measurement and control instruments on the vessel to monitor the parameters of the working medium, in order to ensure the safe use of the pressure vessel and the normal progress of the process.

Basic knowledge of openings and pipe connections in pressure vessel shells

Due to process requirements and maintenance needs, various sizes of holes are often made on the cylindrical body or heads of pressure vessels, or connecting pipes are installed, such as manholes, handholes, sight glass holes, material inlet and outlet connecting pipes, as well as openings for installing pressure gauges, level gauges, safety valves, temperature measuring instruments, and other connecting pipes.

Pressure vessel combined cylinder and sealing device

The wall of the cylinder is composed of two or more layers of discontinuous materials in the thickness direction. The composite cylinder can be further divided into two main categories: multilayer and wound types based on structure and manufacturing methods.

Introduction to Single-Layer Cylindrical Pressure Vessels

The wall of the cylinder is made of a single material in the thickness direction, meaning the wall has only one layer (the anti-corrosion layer applied for preventing internal medium corrosion is not included). Single-layer cylinders can be further divided into several types based on the manufacturing method, including single-layer rolled and welded type, integral forged type, forged and welded type, and non-welded bottle type.

Basic structure of pressure vessel equipment manufacturing

Pressure vessels are typically welded structures composed of plates and shells. Among the pressure components, the corresponding shells for cylindrical bodies, spherical tanks (or spherical heads), elliptical heads, dish-shaped heads, spherical crown heads, conical heads, and expansion joints are cylindrical shells, spherical shells, elliptical shells, spherical crown + ring shells, spherical crowns, conical shells, and annular plates + ring shells.
