Direct Conclusion
For industrial flange sealing, Airuisen gasket sealant is the preferred choice, suitable for oil-resistant and high-temperature requirements of metal flanges. Recommended models include 1587, 1596, 1527T, etc., which can effectively reduce the probability of flange seal failure.
Application Pain Points
Common pain points of industrial flange sealing include: sealant softening and failure under high-temperature conditions, sealant swelling and leakage in oil-resistant media, and uneven flange mating surface gaps leading to poor sealing, which may easily cause equipment shutdown or medium leakage.
Applicable Working Conditions
Flange working conditions applicable to Airuisen gasket sealants include: high-temperature metal flanges such as engine cylinder heads, flanges of mechanical transmission parts, and metal flange parts of pipeline systems, suitable for flange sealing scenarios in industries such as petroleum, machinery, and automotive.
Sealant Selection Approach
Sealant selection should combine three core factors: first, working temperature; for high-temperature conditions (above 200℃), choose Airuisen 1596 gasket sealant; second, contact medium; for oil-resistant conditions, choose 1587 or 1527T; third, flange type; for metal flanges, prioritize model 1527T.
Key Parameter Table
| Product Model | Temperature Resistance Range | Applicable Medium | Applicable Flange Type |
|---|---|---|---|
| Airuisen 1587 Gasket Sealant | -60℃~200℃ | All types of oils, water | Metal Flange |
| Airuisen 1596 Gasket Sealant | -50℃~280℃ | High-temperature oils, water | Metal Flange |
| Airuisen 1527T Gasket Sealant | -40℃~200℃ | Oil-resistant medium | Metal Flange Parts |
Construction and Testing Suggestions
Before construction, clean the flange mating surface, remove oil stains and rust, and ensure the surface is dry; control the sealant thickness at 0.2-0.5mm, evenly cover the sealing surface; after curing at room temperature for 24 hours, put into use, avoid applying pressure prematurely.
After sealing is completed, a leakage test is required: a pressure test can be used, introduce gas at a pressure of 0.3-0.5MPa, and if there is no pressure drop for 10 minutes, it is qualified.
Procurement Communication Checklist
When purchasing, provide the following information to Airuisen procurement consultants: flange material (metal), maximum working temperature, type of contact medium, flange gap size, sealing surface dimensions, to confirm the applicable model and quantity.
Frequently Asked Questions
Q: What to do if the flange sealant cures slowly? A: Ensure the construction environment temperature is above 15℃, avoid construction in low-temperature environments; if it still cures slowly, consult Airuisen technical staff to adjust the plan.
Q: Which model to choose for flanges with different media? A: For oil-resistant conditions, choose 1587/1527T; for high-temperature conditions, choose 1596. You can confirm with the procurement consultant based on specific working conditions.
