1
Q: How do I choose the right flange for my joint?
A: Choose based on the joint structure and application, not just pipe diameter. For two pipe ends that are bolted face-to-face, a flat butt-joint flange with a gasket is normally used. For joints that need to be opened often, a V-band flange with a matched clamp profile is convenient to service. For a turbo inlet, choose a T3 or T4 turbo flange that matches the turbine housing. Male/female interlocking flange pairs are generally designed for metal-to-metal sealing without a gasket.
2
Q: Which material should I choose — stainless steel or carbon steel?
A: Stainless steel offers better corrosion resistance, especially in wet, salty or chemically exposed environments. Carbon steel is a cost-effective option for many exhaust and high-temperature applications, but it normally requires a protective surface treatment to improve corrosion resistance. The right choice depends on working temperature, corrosion exposure, welding requirements and cost.
3
Q: Can the flanges be customised?
A: Yes. We support custom flanges based on your drawing, photo or sample, including non-standard sizes, bolt-hole patterns, port shapes and surface finishes. Custom marking and packaging are also available on request.
4
Q: How long do the flanges last, and can they be reused?
A: Service life depends on the material, working temperature, corrosion exposure and installation quality. Stainless steel generally provides better corrosion resistance, while coated carbon steel can be a cost-effective option for many applications. Flanges can normally be reused if they remain flat, undamaged and free from significant corrosion. A distorted, cracked or heavily corroded flange should be replaced rather than reused.
5
Q: Why does my joint still leak after I tighten the bolts?
A: A gasket alone does not guarantee a leak-free joint — flange flatness, alignment, gasket type and pipe fit all matter. Check that both faces are flat and clean, that the gasket is centred and the correct type, and that the pipework is not pulling the joint out of alignment. If a flange face is significantly warped, replacing the gasket alone may not solve the leak.
