Flexible metal accordion connector consists of various components and parts. These components and components together will give these products great resilience and flexibility. We are going to introduce these parts to you, my dear ones.
Accordion Fitting Parts
- Blues: A flexible metal accordion connector has a jumper. This jumper, which is made up of several rings, creates flexibility in the joints. Jumper material can be ferritic stainless steel 409, 410, 430, austenitic stainless steels, AISI 304, 316 L, 321, color metals AL, CU, chrome steels such as Corten Steel, nickel based alloys, carbon steel (ST 14, ST 37, ST 52, …) and … Be. Material type is selected according to temperature and fluid type.
- Flange: A flange is a common standard coupling that is chosen according to factors such as temperature and pressure. The most common standards available for flanges are JIS, BSI, ASME and DIN.
- Internal wall: The inner wall is the part that is fixed in a flexible metal accordion connection from one side and free from the other. This section is responsible for bonding against abrasion, corrosion and … Prevent it. In addition, this section is able to prevent turbulence and pressure drops. The inner wall is a great heat shield for the jumper at high temperatures. This part creates an insulator for the connection. Regarding design, application, choice of interior wall and … In the following sections، we will explain to you in detail.
- Reinforcement rings: These rings are placed at the end of the root of the accordion blues. Reinforcement rings are responsible for strengthening the accordion part of the connection against the pressure of fluid passage. A particular type of ring has a cross-sectional surface in the shape of T. These types of rims have the task of splitting the movement between the blades of the accordion jumper.
- Kevlar: Kevlar is a section in flexible metal accordion connector. Stress analysis in accordion joints follows a rule called thin wall shell analysis. Therefore, the force that results from the pressure of the fluid will create environmental stresses in the simplicity of the blues. In high-pressure cases, a blues ring is used to reinforce the simplicity of the blues that is not found in the form part. We call this ring Kevlar.
- Movement Control: This section has different shapes according to the type of application of the joints. The task of this section is to resist the force of trust. If we need something to adjust or control the connection movements, this is the best option.
- Cover: Other components of flexible metal accordion connector can be pointed to the cover. The cover is responsible for protecting the connection from external pressures and impacts. Also, if there is a possible leak in the pipe, it will prevent the spraying of the fluid out.
- Equipment for transportation: The most sensitive part in a flexible metal accordion connector is its accordion texture. There is a possibility of damage to this tissue during transfer. These equipment are responsible for basic transportation. During transportation for different reasons such as different directions, connection weight, etc. The shape of the accordion part may change. Or the pieces may be put together so that the connections come in contact with each other.
Therefore, measures must be taken to prevent collision and damage to a flexible metal accordion joint. Note that these equipment are not designed to perform and prevent fluid pressure during the thrust test. Therefore, they must be disconnected from the connection before launching and testing the pipeline. In some cases, harnesses are designed for transportation that are in the form of bolts and nuts. These controls are used for initial adjustment.
