ASTM UNSS31603 316L/00Cr17Ni14Mo2/1.4404 DN 15-1200 Class150-Class2500 SS 316L Threaded Hex Head Bushing and Flush Bushing

Product OverviewOur carbon steel bushings (also called pipe reducers or threaded bushings) are compact pipe fittings designed to connect pipes with different internal/external thread sizes, enabling smooth size transition while saving installation space. Crafted from high-quality carbon steel via precision machining and threading processes, these bushings feature excellent thread accuracy, strong mechanical strength, and reliable corrosion resistance. They are valued for easy on-site installation (no welding required), tight sealing performance, and cost-effectiveness, making them an essential component for low-to-medium pressure piping systems in industrial, commercial, and municipal projects globally.Product Specifications1. Material GradesWe offer a range of carbon steel grades to match diverse application requirements: • A105: The most widely used grade for carbon steel bushings, featuring good ductility and thread machinability, suitable for general low-to-medium pressure (up to Class 300) and ambient-temperature systems (e.g., water supply, gas lines). • A350 LF2: Low-temperature resistant grade (minimum operating temperature -46°C), ideal for cold-environment piping like refrigeration systems or outdoor pipelines in frigid regions. • 1045 Carbon Steel: High-strength grade with enhanced hardness (HRC 20-25), designed for high-pressure (up to Class 600) industrial systems requiring durable thread connections. • Custom Grades: Available upon request, compliant with international standards (ASTM, ASME, DIN, GB) or customer-specific drawings to meet special needs (e.g., corrosion-prone or high-vibration environments).2. Structural & Dimensional Parameters• Thread Type: Compatible with global thread standards, including: ◦ NPT (National Pipe Taper): Tapered threads for self-sealing, widely used in North American markets (water, gas, oil lines). ◦ BSPT (British Standard Pipe Taper): Tapered threads for medium-pressure systems, common in European and Asian markets. ◦ BSPP (British Standard Pipe Parallel): Parallel threads (requires gaskets for sealing), suitable for low-pressure fluid transmission.
