Respected Clients and Partners,
Lanyu Machinery is proud to announce a major technological advancement! We have introduced the longest domestically available specialized equipment for surface strengthening of non-magnetic steel, which is now officially operational. This upgrade enables us to provide you with higher-quality, longer-lasting non-magnetic steel products and services.
This equipment enhancement fully supports the strengthening treatment of our self-developed patented LYNTM9 non-magnetic steel series (including non-magnetic drill collars, spiral drill collars, stabilizers, etc.), enabling comprehensive internal and external surface strengthening. The service life of these products has been increased by 20%-30% compared to conventional methods, and we guarantee stable performance in compliance with API 7-1 standards for up to 5 years. Our products are delivered in a high-strength, durable state right out of the factory.
Key advantages of the equipment:
Capable of processing workpieces up to 10 meters in length
Internal bore as small as Φ25.4mm, external diameter range: Φ50-300mm
Thread processing length up to 200mm
Post-strengthening: No magnetic increase for 5 years, core performance improved by an additional 20%-30%
We are also introducing two convenient services to enhance your efficiency and quality:
🔄 Used Component Recycling and Exchange
Your used non-magnetic steel products can be exchanged for products in the same series or other types of petroleum drilling tools. This promotes recycling, cost savings, and green efficiency.
🔧 Incoming Material Strengthening Processing
We welcome you to provide your own materials, and we will offer professional internal and external surface strengthening along with customized solutions. Enjoy flexible processing and controllable lead times.
🎁 Raw Material Purchase Benefits
