GLL threaded parts use 304/316L medical grade stainless steel as the core material, giving the product three core characteristics:
1. Super corrosion resistance : In corrosive environments such as moisture, acid and alkali, GLL threaded parts can effectively resist oxidation and rust, and are especially suitable for high-corrosion scenarios such as chemical industry, food processing and marine engineering. Among them, 316L material is optimized for high salt spray and strong acid environments, becoming the first choice for chemical equipment and offshore platforms.
2. Wide temperature range and stable structure : From ultra-low temperature of -200℃ to high temperature of 800℃, GLL threaded parts can always maintain structural strength to meet the needs of extreme working conditions such as polar scientific research, aerospace, etc.
3. Medical-grade cleanliness standards : The surface is designed to be non-porous and complies with FDA and EU food contact material certifications. It is widely used in medical devices, pharmaceutical equipment and other fields with strict cleanliness requirements.
GLL has pushed the precision of metric threads to a new level through automated CNC machining centers and intelligent detection systems:
1. High-precision machining system :The thread pitch and center diameter tolerances are strictly controlled within ±0.02mm, ensuring 100% compatibility with standard parts and eliminating leakage or assembly problems caused by dimensional deviations.
2. Surface strengthening black technology :The rolling thread process is used to increase the surface hardness to HRC≥45, while reducing the friction coefficient and significantly extending the service life. After testing, this process improves the wear resistance of threaded parts by more than 30%.
GLL original “cold extrusion molding + laser calibration” process has achieved two major technological breakthroughs :
The thread tensile strength is increased by 20%, and the torque bearing capacity is better than the DIN/ISO standard; Laser calibration ensures zero deviation of thread angle and verticality, suitable for high-precision assembly scenarios.
GLL core advantage: full scene coverage from corrosion resistance to customization
1. Scenario-based corrosion resistance solution 316L material is specially designed for high salt spray (such as offshore platforms) and strong acid (such as chemical reactors) environments, and there is no risk of rust in long-term use.
2. Millimeter-level precision guarantee The thread tolerance is strictly controlled within ±0.05mm to ensure sealing performance and assembly stability, and is suitable for precision scenes such as medical equipment and high-pressure containers.
3. Flexible customization service Supports personalized customization such as special threads (left-handed, fine teeth), special-shaped heads (hexagonal flanges, heads with holes), etc., to meet the unique needs of non-standard equipment.
FAQ
