Welded Pipe
1. Manufacturing Process
By bending a steel sheet or steel strip into a tube and then welding the joint by a welding process. Common welding methods include high-frequency welding and spiral welding.
2. Appearance
There are obvious welds on the surface, but modern technology can be treated to make the welds less obvious. The wall thickness is uniform and the precision is high.
3. Performance
The bearing capacity is relatively low, but the cost is low, easy to process and install. The weld is its weakest link, but with technological advances, the quality of the weld has improved significantly.
4. Application Field
Widely used in tap water engineering, petrochemical industry, agricultural irrigation, urban construction and other fields, suitable for low pressure fluid transport and building structure.
5. The Cost
Recyclable, environmentally friendly and compliant with modern green building standards.
Seamless Pipe
1. Manufacturing Process
By perforating the solid tube billet or steel ingot, and then through hot rolling, cold rolling or cold drawing and other processes, there is no weld inside.
2. Appearance
Smooth surface, no weld, good integrity, beautiful appearance. However, due to the limitation of manufacturing process, there may be some non-uniformity of wall thickness.
3. Performance
High bearing capacity, excellent corrosion resistance and high temperature resistance, suitable for high pressure, high temperature and other harsh environment.
4. Application Field
Mainly used in petroleum geological drilling, petrochemical cracking, boiler tube, high-precision structural steel pipe for aviation, etc., suitable for high pressure, high temperature and corrosive environment.
5. The Cost
The manufacturing process is complex, the price is high, but the performance is superior.
Welded pipe and seamless pipe each have their own advantages, the selection should be based on specific needs. If high pressure capacity and corrosion resistance are required, seamless pipes are the better choice; If the cost and production efficiency requirements are higher, welded pipes are more suitable.
Highly customized design: Flexible size: Support customized pipe diameter, wall thickness, length and bending Angle, perfect for the structural needs of different bicycle models (such as mountain bikes, road bikes, folding bikes).
Lightweight and performance optimization: Through the scientific design of the pipe wall thickness, the overall weight is reduced while ensuring the strength, and the control flexibility and riding speed of the bicycle are improved.
High strength and durability: 20# steel material is with high strength and toughness, it can withstand the impact, vibration and long-term load during riding, and is suitable for key components such as bicycle frame and bracket to ensure riding safety and stability.The use of advanced welding technology, the weld is uniform and firm, the overall structure has strong fatigue resistance, and extends the service life.
Economical and efficient: The cost of 20# steel is controllable, combined with customized production to reduce material waste, cost-effective, suitable for small and medium-sized batch orders.
Environmental protection and sustainability: Steel can be 100% recycled, in line with the trend of green manufacturing, helping the brand to enhance the environmental image.
Frame connection tube: As the main beam, lower tube or rear triangle support parts of the bicycle frame, the customized size and threaded interface can be adapted to different types of vehicles (such as mountain bikes, road bikes, folding cars) to ensure the balance of rigidity and lightweight frame.
Steerer Tube: Used to connect the front fork to the handlebars, the precision welded and threaded design improves the stability of the steering system, especially for mountain bikes that require high intensity to cope with rough terrain.
Shelf support: The lightweight and torsion resistance of the custom pipe can carry the weight of luggage, suitable for long-distance touring or commuter cars, and the threaded interface allows quick installation/removal of the shelf.
Fender/kettle holder fixed tube: Modular expansion of accessories through threaded connection to meet the individual needs of users.
Handlebar Stem: Threaded welded tubes are used to secure the handlebar and steering system to ensure precise handling, especially for the high-intensity demands of racing road cars or gravel trucks.
Pedal Spindle: High-precision threading ensures a reliable connection between the pedal and the crank, reducing the risk of loosening during riding.
Seatpost: The customized length and diameter of the threaded tube can be adapted to different frames, and the surface anti-corrosion treatment extends the service life, especially for outdoor riding frequently.
Seat support bar: Adjustable height and Angle through thread to enhance riding comfort, suitable for commuter or recreational bicycles.
Folding joint pipe: with customized welding process and threaded interface, the frame can be quickly folded and locked, taking into account structural strength and portability, and meeting the needs of urban commuting
1Q: Why choose 20# steel over other materials (such as aluminum alloy or 304 stainless steel)?
1A: 20# steel has an excellent balance of strength and toughness, costs less than stainless steel and is easy to weld, and is suitable for bicycle parts that require high load (such as frames, shelf supports).
2Q: What parameters do I need to provide for custom welded pipes?
2A: Pipe diameter, wall thickness, length, bending Angle, thread specification (e.g. M8×1.25) and surface treatment requirements should be provided.
3Q: How long does it take to customize the products?
3A: The standard order production cycle is 7-15 days (depending on complexity), and expedited service is supported.
4Q: Will customized production lead to significant cost increases?
4A: 20# steel raw material cost is low, and small batch customization using modular process (such as unified welding after cutting), the cost of a single piece is controllable. Batch orders (more than 50 pieces) can enjoy gradient quotation, more cost-effective.
5Q: What reports will you provide when you submit the samples?
5A: Dimensional report with bubbled print, raw material cert.
