The cylinder is also called the drum, it is the steam boiler
essential ancillary equipment, cylinder is widely used in power
generation, petrochemical, steel, cement, construction and other
Performance structure of cylinder:
The cylinder is the main auxiliary equipment of the boiler, which
is used to distribute the steam generated during the operation of
the boiler to various pipelines. The cylinder is the pressure
equipment and belongs to the pressure vessel.The main function of
the sub-cylinder is to distribute steam, so there are several seats
on the sub-cylinder connecting the boiler main steam valve and the
steam distribution valve, so as to separate the steam in the
sub-cylinder to where it is needed.The main pressure components of
the cylinder are: steam distribution seat, main steam seat, safety
gate seat, steam trap seat, pressure gauge seat, thermometer
seat;All the materials including head, shell and flange are
Q235-A/B, 20g and 16MnR; Main products include: 159-tu1500; working
pressure: 1-2.5mpa; working temperature: 0 ~ 400℃; working medium:
steam, hot and cold water; compressed air; etc.
Technical specifications of cylinder:
When the medium is steam, it shall be designed in accordance with
the provisions of Pressure Vessel Regulations, and the diameter,
material and thickness of the cylinder shall be determined. General
principles: the diameter of the cylinder shall be 2-2.5 times of
the maximum diameter of the pipe. Generally, it can be determined
according to the flow rate of the fluid inside the cylinder.1. The
equipment specification of the specifications of the cylinder is
DN200-48 "), specific container volume set by the user, design
pressure is 1.43 MPa commonly, design temperature < 350 ℃, for
steam as the working medium, container category for Ⅰ class
pressure vessel.2. Equipment selection table
1. provides flow, pressure, temperature parameters.
2.Provide diameter and quantity of steam inlet, steam outlet and
steam drain pipes.
3.whether the cylinder size requirements.
4.whether to pressure gauge, thermometer, safety valve v, cylinder
1. standardized production.B No matter the size of the cylinder
products, the circular seam adopts automatic welding technology,
which makes the products beautiful, safe and reliable.
2.Complete varieties and wide application scope.Working pressure up
3. Each cylinder is manufactured, inspected and accepted according
to national standards.The cylinder is inspected by the factory and
inspected by the local bureau of Quality and Technical
Supervision.Ensure the quality of cylinder.Cylinder inspection
certificate drawings, etc.
4.If the user has special requirements, the cylinder can be
designed and manufactured according to the user's needs.
