1.High Precision & Tight Tolerances:
Achieves strict dimensional tolerances (ISO H7-H11) and ultra-smooth inner surface (max Ra 0.4μm), ensuring optimal performance in precision hydraulic systems.
2.Superior Material Quality:
Uses premium raw materials from top Chinese steel makers (TPCO, Bao Steel, etc.), with a range of high-performance grades (ST52.3, E355, SAE 4140, 304L stainless steel) for durability and pressure resistance.
3. Seamless & High-Pressure Resistance:
Made from seamless cold-drawn tubes, enabling it to withstand high pressure, making it reliable for hydraulic cylinder applications.
4. Advanced Manufacturing Processes:
Utilizes advanced techniques like honing and skiving & roller burnishing (SRB) for enhanced surface finish and structural integrity.
6. Strict Quality Control:
Features a dedicated QC team (10+ members) conducting rigorous inspections (chemical analysis, tensile testing, roughness checks) and a total quality management system to guarantee consistency.
7. Customization Flexibility:
Accepts small orders (even single pieces) and offers customizable sizes (metric: 30-800mm ID; imperial: 1.5-30" ID) and lengths (up to 14 meters) to meet diverse needs.
8. Excellent Weldability:
Facilitates easy integration into cylinder manufacturing, reducing production complexity.
9. Reliable Packaging:
Protected with anti-rust oil, plastic/steel end caps, and seaworthy packaging (wooden cases) to prevent damage during transportation.
10. Global Certification & Recognition:
Certified by ISO 9001, API, JIS, etc., and trusted by customers worldwide (USA, Canada, UAE, South Africa, etc.) with a strong market reputation.
1.Hydraulic and Pneumatic Cylinders: Core component for manufacturing and repairing hydraulic cylinders and pneumatic cylinders, used in industrial machinery, construction equipment, and automation systems.
Why Choose Our Tubing?
At Besdrill, we are committed to delivering excellence in every component we manufacture, and our tubing are no exception. Here's why customers worldwide choose our solutions:
Quality is a core priority: raw materials are sourced from top Chinese steel manufacturers such as TPCO, SHA STEEL, and BAO STEEL. A dedicated QC team of over 10 members conducts rigorous inspections (including chemical analysis, tensile testing, dimension checks, and roughness testing) before shipment, supported by a mature total quality management system. The company holds certifications including ISO 9001, API, and JIS, ensuring compliance with international standards. East Ai's product range includes honed tubes, skived & roller burnished tubes (SRB tubes), chrome-plated rods, hydraulic cylinders, and cold-drawn tubes, with materials covering carbon steel (SAE 1020, ST52, E355, SAE 4140) and stainless steel (304L, 316L). The company supports OEM and ODM services, accepting both small and large orders to meet diverse customer needs. With a global customer base, East Ai exports its products to countries including the USA, Canada, Mexico, Saudi Arabia, UAE, South Africa, Russia, Thailand, Australia, and Brazil, earning trust for its reliable quality and professional service.
In addition to providing you with Tubing, we can also offer you other types of water well drilling. For more information, please consult us.
