Application of High Pressure Clamp Fittings

High-pressure clamps are the go-to for attached piping or hoses in food factories where liquid or solids are being moved to the equipment used to manufacture food. Additionally, high-pressure clamps are sanitary and can be taken off regularly and cleaned in order to meet the high-performance requirements seen in food factories today, where preventative maintenance is required frequently.

In pharmaceutical piping, high-pressure clamps allow for the quick connections to be made while keeping pressure stable and allow the maintenance of equipment, along with modification to the layouts of the production line.

Currently, in some brewing, beverage and fermentation operations, high-pressure clamps are the primary connection method between the vessels used to store the liquids and the pipelines that transport these liquids. This provides a stable operation in cases of pressure fluctuations that can be caused by the fermentation system and fermentation.

In process piping in the chemical industry, high-pressure clamps are used to connect and transport chemical processes from a variety of process media; and their stainless-steel construction allows them to withstand the challenges of most industrial manufacturing applications.

In bioprocessing and laboratory applications, high-pressure clamps connect small reactors and fluidic lines, providing a compact solution that allows for modular set-ups of bioprocessing equipment.

The main difference between the two is the capacity of the fittings for the working pressure. The high-pressure clamp fittings are generally designed to work with a working pressure of around 1200 psi.
On the contrary, the capacity of the standard tee clamp fittings for the working pressure depends on the clamp used with the standard tee clamp fittings. The clamp can either be a high-pressure clamp or a standard sanitary clamp.
When installing high pressure clamp fittings, it is important to note that the ports of the pipes are aligned correctly, together with the gaskets. The clamp should be tightened uniformly, not too tight or too loose, in order to ensure that pressure is not unevenly distributed, which could affect sealing performance. In addition, clamp parts should be of suitable specification depending on system pressure requirements.
High pressure clamp fittings offer several advantages over welded connections, including that this type of fitting allows for easy assembly or disassembly of connected parts without welding, which is very convenient in situations where equipment needs maintenance or even cleaning.
Most high pressure clamp fittings can be used with standard sanitary clamp piping. However, for a high pressure system, it is normally necessary to use corresponding reinforced clamp fittings with appropriate gaskets to ensure that the system can operate at increased working pressures.
What is a High Pressure Clamp Fitting?
A high-pressure clamp fitting is a type of fitting that is used for connecting two pipes in a high-pressure fluid system. The fitting ensures that a secure and stable connection is established between two pipes in a high-pressure system, while also ensuring sealing performance. The high-pressure clamp fitting is comparable to other clamp fittings but is constructed in a sturdy manner that ensures it can perform under high pressures.
Composition of High Pressure Clamp Fittings
High-pressure clamp fittings have a number of key components that play a crucial role in ensuring that the connection is stable and that the sealing process is effective in high-pressure conditions.
Fitting Body (Ferrule)
The body of the fitting acts as the main component in the high-pressure clamp connection. The body is usually made from high-strength stainless steel, such as SS304 and SS316. The end face is subjected to precise machine work to create a surface that can mate with the opposite end face of the equipment or the pipe connection.
High-Pressure Clamp
The high-pressure clamp presses the two end faces of the fitting firmly together. The high-pressure clamp has a thicker and stronger design compared to the standard clamp in a sanitary connection.
Gasket
The gasket is placed between the two end faces of the joint. When subjected to the clamp, it acts as a sealant that helps prevent leakage of the fluid. Depending on the type of medium used and the temperature requirements for the project, the gasket material used may be EPDM, PTFE, or silicone.
Bolt and Nut
The bolts and nut help hold the clamp in place. This ensures that the joint is firmly held together at all times when the system is in operation.
Working Principle of High Pressure Clamp Joints
The working principle of high-pressure clamp joints is based on ensuring proper connections between two pipes through the coordination of clamp structures and elastic sealing rings. The process of creating a proper connection through a high-pressure clamp joint is done through the following steps:
Step 1: Connection
The first step is to place the elastic C-shaped rubber sealing ring over two ends of the pipes that have annular grooves. The lubricant is applied before this process takes place.
Step 2: Engagement
Subsequently, position two metal clamp plates over the outer edge of the seal. Ensure that the inner flanges of the clamp plates engage the annular grooves of both the pipes precisely. Tighten the bolts of the clamp plates to create a stable force, thereby engaging the two sections of the pipes firmly.
Step 3: Sealing
Upon the commencement of the transportation of the fluid by the pipeline system, the fluid enters the inner cavity of the C-ring seal. The fluid, upon increasing the pressure, pushes the seal from the inner side, causing the seal to engage more firmly with the outer wall of the pipe as well as the inner wall of the clamp, thereby creating a more reliable seal.
Concurrently, the clamp, which is engaged with the grooves, ensures a strong pull-out resistance, thereby preventing the blowing apart of the joints, even under high-pressure conditions.
Pressure Ratings for High Pressure Clamp Fittings
High-pressure clamp fittings are designed for use in piping systems that demand an increased level of pressure rating. When compared to standard sanitary clamp connections, high-pressure clamp fittings exhibit reinforced structural strength. This allows for the formation of a stable connection that can withstand the required level of pressure.
In standard configurations, the level of pressure rating for high-pressure clamp fittings is around 1200 psi. However, the rating may vary depending on factors like pipe diameter, gasket materials, and temperature.
Impact of Size on Pressure Rating
In clamp connections, the level of pressure exerted on the pipe is greater for larger pipe sizes. Therefore, high-pressure clamp fittings of different sizes may vary with regard to their respective pressure ratings. The level of pressure rating is greater for smaller pipe connections. The connections for larger pipe diameters are reinforced to ensure stability.
Impact of Gasket Material on Pressure Performance
Gaskets form an integral part of the clamp connections. The gasket materials available in the market vary with different pressure and temperature resistance.
For example, PTFE gaskets are known for their chemical resistance and high-temperature performance. Similarly, EPDM and silicone gaskets are suitable for a wide range of temperature and media services. The selection of the right sealing materials helps to achieve the stability of the sealing performance.
Impact of Temperature on Pressure Rating
Another factor that affects the clamp connections is the temperature rating of the piping systems. When the temperature is raised, the elasticity of the sealing materials may change. Therefore, it is important to consider the temperature rating of the clamp connections when you are dealing with high-pressure clamp fittings.
Design Advantages of High-Pressure Clamp Structures
In comparison to the standard Tri-Clamps, the high-pressure clamp connections are designed with a thicker clamp or a double-bolt design. This design helps to achieve greater clamping forces with uniform stress distribution. This helps to achieve the pull-out strength of the clamp connections. This is a significant advantage of the high-pressure clamp connections.
