Are your pipe beveling projects always behind schedule?
You know the feeling. You are on a construction site, maybe in the middle of a desert for a pipeline project, or inside a tight ship hull. Your team is ready to weld, but the pipe ends are not ready. The old beveling machine is too heavy to move. The blades get dull after just a few cuts. The angle is not right, so the welders have to grind for hours to fix it. This costs you money. It wastes time. And it makes your clients angry.You need a blade that cuts fast, lasts long, and fits your machine perfectly. You need a blade that handles stainless steel without breaking and cuts carbon steel like butter. You need the Kaidelong beveling machine blades.
What makes Kaidelong blades different?
We do not just sell metal pieces. We sell a solution for your pipe fabrication. Our blades are made for the real world. They work in oil fields, chemical plants, and nuclear power stations. We use the best materials. We have High-Speed Steel (HSS) for general use. We have solid carbide for hard materials. We even have special coatings for stainless steel and alloy pipes.Our factory has over 10 senior engineers. They study how the blade cuts. They design the chip breaker geometry. This means the blade cuts smoothly. It does not vibrate. It does not chatter. You get a clean, smooth finish every time. The welders love this because it means less grinding work.
A blade for every pipe and every material
Pipes come in different sizes and materials. One blade does not fit all. That is why we have a huge range of products. Whether you have a small handheld beveler or a big hydraulic machine, we have the right tool for you.
Carbon Steel and Alloy Steel Blades
If you are working on standard pipelines, our standard HSS blades are perfect. They are tough. They resist impact. You can re-sharpen them many times. This makes them very cheap to use over a long time. We have blades with a cobalt content of 6%. This helps them stay hard even when they get hot from fast cutting.
Stainless Steel and Special Alloy Blades
Stainless steel is sticky. It work-hardens. This means it gets harder as you cut it. Normal blades fail here. Our Kaidelong blades for stainless steel use special grades. We use TiAlN coating. This is a nano-structure coating. It reduces friction. It stops the material from sticking to the blade.We also have blades for Inconel, duplex steel, and other high-temperature alloys. These blades have a very sharp edge. They cut with low force. This is important for thin-walled pipes where you cannot push too hard.
Different Bevel Angles and Shapes
You need different shapes for different welds. We provide all the standard types:
- V-Type: The most common. Usually 30° or 37.5°. Good for general welding.
- U-Type: For thick walls. It has a rounded bottom.
- J-Type: For special heavy wall applications.
- Compound Bevels: Custom shapes for complex joints.
We also have flat facing tools (0°). You can use these to clean the pipe end before beveling. This ensures the pipe is perfectly square.
Technical Specifications You Can Trust
We believe in transparency. You need to know exactly what you are buying. Here are the details of our blade series.
| Blade Type | Material | Hardness (HRC) | Suitable Pipe Material | Cutting Angle | Application |
|---|---|---|---|---|---|
| SWRMH | HSS + Cobalt | 62-65 | Carbon Steel, Alloy Steel | 90° | Sealing weld removal, back gouging |
| OBMH | Carbide (K20/K30) | 90+ | Stainless Steel, Inconel | 37.5° | External beveling, high precision |
| STWRMH | HSS (M42) | 64-66 | High Strength Steel | 37.5° | Strength weld removal, no damage to pipe |
| Kaidelong TiN | HSS + TiN Coating | 63-65 | Stainless Steel, Aluminum | 30° / 45° | High speed cutting, anti-stick |
General Technical Data:
- Blade Life: Normal HSS blades can do about 80 bevels. Carbide blades can do over 500 bevels.
- Surface Finish: Ra 3.2 to Ra 6.3 micrometers. This meets most welding standards like AWS and ISO.
- Tolerance: Angle error is within ±0.5°. Size error is within ±0.05mm.
- Shipping Weight: Standard pack is about 0.5kg to 2kg. Express shipping is easy.
Fits Your Machine Perfectly
You might worry if these blades fit your machine. Do not worry. We make blades for almost all internal expansion beveling machines.
For T-Type and Y-Type Machines
These are the portable, manual feed machines. They are very common in maintenance work. Our blades use a simple locking system. You can change a blade in less than 2 minutes. You do not need special tools. Just use the wrench that came with your machine.
For II-Type (Heavy Wall) Machines
These are the big machines for thick pipes (up to 75mm wall thickness). They use automatic feed. Our blades for these machines are heavier. They have a stronger shank. They resist the high cutting force. We use indexable inserts for some models. When one edge is dull, you just turn the insert. No need to change the whole tool.
For Pneumatic and Hydraulic Machines
Pneumatic machines vibrate a lot. Hydraulic machines have huge power. Our blades are designed with a reinforced core. They absorb vibration. This prevents chipping. We work with brands like Kaidesheng, Monghao, and other OEMs. Our blades are a perfect drop-in replacement.
Real World Success Stories
Do not just take our word for it. Look at where our blades are working.Case 1: West-East Gas PipelineThis is one of the biggest projects in the world. The pipes are huge. The walls are thick. The site is remote. They used our carbide blades. The result? They changed blades once a week instead of once a day. This saved them huge labor costs. The project finished on time.Case 2: LNG Tanker ConstructionLNG ships need perfect welds. Zero leaks allowed. The angle must be exact. They used our coated stainless steel blades. The surface finish was Ra 3.2. The X-ray tests passed 100%. The shipyard ordered 50 sets immediately.Case 3: Nuclear Power Plant MaintenanceSpace is tight in a nuclear plant. Radiation is a risk. Workers cannot stay long. They need speed. Our high-feed blades cut the bevel in 3 minutes per pipe. This reduced worker exposure time. Safety first.

Frequently Asked Questions
Q: Can I sharpen these blades?A: Yes. Our HSS blades can be re-sharpened 5 to 10 times. Just use a standard tool grinder. Do not overheat the steel. Carbide blades are harder to sharpen. You need a diamond wheel. But they last so long that you might not need to sharpen them often.Q: Do you have blades for small pipes, like 16mm?A: Yes. We have blades for DN15 to DN20mm pipes. These are for the small T-type machines. The shank is thinner to fit the small space.Q: What is the MOQ (Minimum Order Quantity)?A: For stock items, you can buy just 1 set. For custom OEM orders, the MOQ is usually 50 pieces. But we are flexible. Talk to our sales team.Q: How do I pay?A: We accept T/T (Bank Transfer), PayPal, and Alibaba Trade Assurance. Trade Assurance is safe for you. We only get the money after you receive the goods.
