Non-Metallic Gaskets – High-Performance Sealing Solutions
At Vrushabh Engineering, we are dedicated to producing high-quality non-metallic gaskets tailored to fulfil a diverse array of industrial sealing requirements. Our gaskets are manufactured using top-grade materials and cutting-edge production techniques, ensuring consistent sealing performance across varying pressure and temperature scenarios. Complying with the rigorous standards set by ASME B16.21, our non-metallic gaskets offer a trustworthy solution for sectors that demand robust, high-performance sealing components.
What are non-metallic gaskets?
Non-metallic gaskets are constructed from flexible, soft materials such as aramid fibre, glass fibre, elastomer, Teflon (PTFE), and graphite. These materials are chosen for their durability and capacity to adapt to irregularities on flange surfaces, thereby guaranteeing a secure and efficient seal. In contrast to metallic or semi-metallic gaskets, non-metallic options are specifically designed for moderate pressure and temperature applications, making them particularly suitable for industries such as chemical processing, food and beverage, pharmaceuticals, and power generation.
At Vrushabh Engineering, we produce non-metallic gaskets from a selection of high-performance materials, including:
- Aramid Fiber – Renowned for its strength and thermal resistance.
- Glass Fiber – Offers exceptional thermal stability and chemical resistance.
- Elastomer – Provides flexibility and resistance to chemical deterioration.
- Teflon (PTFE) – Exhibits high resistance to chemicals and extreme temperatures.
- Graphite – Delivers outstanding sealing performance in high-temperature environments.
Our non-metallic gaskets are available in various shapes, sizes, and thicknesses to accommodate specific application needs, ensuring a dependable and enduring seal across a wide range of operating conditions.
Manufacturing standards and marking
All non-metallic gaskets produced by Vrushabh Engineering adhere to the ASME B16.21 standards, which specify the types, sizes, materials, dimensions, tolerances, and markings for non-metallic flat gaskets. This compliance guarantees that our gaskets fulfil international quality and performance criteria.
Each gasket is meticulously marked to ensure full traceability and identification. The markings include the following details:
- Manufacturer’s name or trademark
- Material designation
- NPS (Nominal Pipe Size)
- Class (Pressure-Temperature Ratings)
- Thickness
- ASME B16.21 marking or tag
The NPS, accompanied by a dimensionless number, indicates the nominal pipe size as defined in ASME B36.10M and corresponds to the reference nominal diameter (DN) utilized in global standards. The class designation indicates the standard flange pressure-temperature ratings as outlined in the relevant flange specifications.
The various tolerances that are followed in Vrushabh Engineering are as follows:
CATEGORY | I.D | O.D |
NPS 12 & smaller | ±1.5 mm (±0.06 in.) | +0.0, −1.5 mm (+0.0, −0.06 in.) |
NPS 14 & larger | ±3.0 mm (±0.12 in.) | +0.0, −3.0 mm (+0.0, −0.12 in.) |
Bolt circle | ±1.5 mm (±0.06 in.) | – |
Center to center of adj. holes | ±1.0 mm (±0.03 in.) | – |
Material selection and application
At Vrushabh Engineering, we recognize that the efficacy of a non-metallic gasket is significantly influenced by the material utilized and the operational conditions. Our non-metallic gaskets are crafted from durable or flexible materials, often incorporating metal or non-metal composites as reinforcements or fillers to improve strength and sealing capabilities.
The responsibility for selecting an appropriate non-metallic gasket material and thickness for a specific application lies with the user. Considerations such as the characteristics of the gasket material, operating temperature and pressure, the nature of the process fluid, and any relevant industry standards or governmental regulations must be taken into account when determining the suitable gasket.
We offer expert assistance to aid clients in choosing the most appropriate non-metallic gasket material based on:
- Corrosive Characteristics of the Fluid – Ensuring compatibility with aggressive chemicals.
- Operating Temperature and Pressure – Selecting materials capable of enduring thermal and mechanical stress.
- Seal Integrity Requirements – Guaranteeing a secure and leak-proof seal under varying load conditions.
- Regulatory Adherence – Complying with industry standards and governmental regulations.
Applications of non-metallic gaskets
Vrushabh Engineering’s non-metallic gaskets find extensive application across various sectors, including:
