Some Installing Tricks and Tips for PTFE Spiral Wound Gasket

To seal the joints of pipelines and flanges gas or liquid inside the gaskets are used. Through the pipelines, the chemical industries, gas, oil and pharmaceuticals industries and many more carry toxic acids.

As emission of such acids can cause damage to the machines as well as the man so to keep the environment safe, they need protection against the leakage of such chemicals and acids.

There are many like Spray Guards, Flange Guards, Earthing Jumpers, Bellow Guards, etc. are some of the safety products and to prevent the leakage of harmful fluids they are installed at the joints of pipelines.

For the same, the spiral wound gasket is used. Moreover, for every industry in various materials and sizes, they are available.

You are required to gather the following information before installing the gaskets for your pipeline, flange or valve, joints:-

Size: Check flange class and whether the pipe size is normal. You need OD and ID if the size is non-standard:

• The thickness of the material
• Bolting dimensions
• 
  
• Nature of The Chemical: The pipelines carrying the chemical could be acid, steam or caustic. Before the installation, check the chemical strength of the material.
• 
  
• Pressure: For the consideration, the flow of the pressure and chemical of the system is required. Choose the spiral wound gasket China wisely either there is maximum pressure or operating pressure.
• 
  
• Temperature: As it is not necessary that every material is heat-resistant the temperature of the chemical matters most whether it is alkaline or acid. Check if the temperature is more than usual or normal.

Installing Tips of PTFE Ring Gasket from spiral wound gasket manufacturer for the chemical industries:-

• Clear the debris and dirt on the surface of the joints and Remove the old gasket before you install the gasket. For this step, you might need aerosol gasket remover or metal flange scrapper.

As this can cause failure in the process of installation don’t neglect.

• As full face types have extreme pressure and more holes cut them easily use ring type gaskets how far it is possible.
• 
  
• Assure the finish of the surface as well as the flatness and avoid the usage of metallic gaskets like the spiral wound gasket. For the complete process, both should be satisfactory.
• 
  
• For precise operation, tighten all the bolts properly.
