CLOSE NIPPLE (TN)

CLOSE NIPPLE (TN) – Ultra-Compact Connector for Tight-Space Piping Systems

The CLOSE NIPPLE (TN) is a highly compact, high-strength pipe fitting engineered to join two female-threaded components with minimal axial space. Featuring external threads on both ends and an extremely short overall length, this fitting is specifically designed for applications where space is severely constrained, such as in instrument lines, valve manifolds, or densely packed piping assemblies. Manufactured using the precision lost wax casting process, it ensures exceptional dimensional accuracy, superior surface finish, and consistent mechanical properties—making it ideal for critical, high-pressure applications in oil & gas, chemical processing, power generation, and marine industries.

Key Features & Benefits

• Ultra-Short Design: The defining characteristic of a close nipple is its minimal length, allowing it to connect two fittings or pipes that are nearly touching. This is crucial for installations in tight quarters where a standard nipple would not fit.

• Dual External Threads: Provides a secure, threaded connection on both ends, creating a rigid and leak-resistant joint that can withstand high pressure and vibration.

• High-Strength Construction: Made from durable materials like stainless steel, carbon steel, or alloy steel, ensuring long-term reliability in corrosive or high-temperature environments.

• Precision Manufacturing: The lost wax casting process guarantees tight tolerances and a smooth finish, which is essential for maintaining system integrity and preventing leaks.

Technical Specifications

• Process: Lost wax casting for superior quality and detail.

• Standards: Complies with international standards including ASTM, JIS, DIN, and BS NF.

• Materials: Available in a variety of materials such as stainless steel, carbon steel, alloy steel, and tool steel to meet specific application requirements.

• Sizes: Offered in a comprehensive range of nominal pipe sizes, from 1/8" up to 4", to accommodate diverse system designs.

• Supply Conditions:

• MOQ: 50 pieces

• Origin: Hebei, China

• Shipment: 30-60 days

• Packaging: Standard export packaging (cartons, plywood pallets).

Applications

This fitting is indispensable in scenarios requiring a robust connection in a minimal footprint. Typical uses include:

• Connecting pressure gauges and sensors to process lines.

• Assembling valve manifolds and instrument panels.

• Making repairs or modifications in existing, space-constrained piping systems. -任何需要短距离、高强度螺纹连接的工业管道应用。
