Product Packaging

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.

Q: What is the difference between a bolt-on exhaust flange and a V-band flange?

A: A bolt-on flange uses bolts and a gasket, making the joint straightforward to install and service, but the gasket is a consumable item that should be replaced when the joint is opened. A V-band joint is more compact and faster to remove, but it requires a matched flange and clamp and good alignment — there is no industry-wide sizing standard for V-band flanges, so components from different makers are not always interchangeable.

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.

What tolerances do you hold on flanges?

A: Tolerances are confirmed feature by feature based on your drawing. Bore, thickness, sealing faces and bolt holes may have different tolerance requirements. The applicable tolerances can be provided with the technical datasheet.

Q: What information do you need to quote a flange?

A: Please provide the application, flange type / joint structure, outside diameter, bore, thickness, bolt-hole pattern and quantity, plus the material and surface finish you need. A drawing, photo or sample helps us confirm the details.
