2. Product Description

2.1 Product Introduction

The supplied pipeline parts cover four core categories, all made of high-quality SS316 or 316L stainless steel to ensure durability and corrosion resistance: 1) Seamless Tubes (1/4″, 1/2″, 3/4″, 1″ sizes, e.g., 2302052, 2302068, 2302089, 2302091); 2) Fittings (elbows, tees, reducers, connectors, e.g., 2115879, 18457949-001, 2115042); 3) Valves (ball valves, check valves, e.g., 11331885-001, 1552161, 20030891); 4) Auxiliary Parts (strainers, pipe nipples, couplings, e.g., 510112, 52024-20-D-8, 52124-SS). Each part is manufactured with precision CNC machining and seamless forming technology, ensuring consistent quality and perfect compatibility with industrial pipeline systems. Key parts like the 510112 Y-type strainer and 1552161 check valve are designed to protect downstream equipment by filtering impurities and preventing backflow.

2.2 Functional Description

Each pipeline part plays a critical role in ensuring the integrity, efficiency, and safety of industrial fluid transmission systems, with clear functional positioning:

• Seamless Tubes (e.g., 2302052 1/4″ SS316, 2302091 1″ 316L): Serve as the core of fluid transmission, transporting liquids, gases, or slurries in industrial processes. The seamless design eliminates weak points (e.g., welds) that are prone to leakage, with a working pressure of up to 1000 psi and temperature range of -20°C to +200°C. 316L stainless steel tubes offer enhanced corrosion resistance for harsh chemical environments.
• Fittings (e.g., 2115879 1″ 90° Elbow, 18457949-001 1/2″ Tee, 2115065 1″ Tube to NPT Connector): Connect tubes of different sizes or directions, ensuring smooth fluid flow and secure connections. Elbows (90°) change fluid direction without excessive pressure loss (pressure drop ≤5 psi); tees split or combine fluid flow; reducers (e.g., 2115854 1/2″ to 3/4″) adapt to different tube sizes, maintaining system efficiency.
• Valves (e.g., 11331885-001 2-Way Ball Valve, 1552161 1/2″ Check Valve, 20030891 1-1/2″ Swing Out Ball Valve): Control fluid flow, pressure, and direction. Ball valves provide on/off control with a service life of ≥50,000 cycles; check valves (1 psi crack pressure) prevent backflow, protecting pumps and downstream equipment; swing out ball valves allow easy maintenance without removing the entire valve.
• Auxiliary Parts (e.g., 510112 Y-Type Strainer, 52024-20-D-8 Pipe Nipple, 52124-SS Coupling): The Y-type strainer (0.062″ mesh) filters impurities from fluids, preventing clogging of valves and pumps; pipe nipples and couplings connect threaded components, ensuring leak-proof joints with a torque resistance of ≥300 N·m.

2.3 Structural Features

All pipeline parts adopt advanced structural design and high-quality SS316/316L stainless steel, tailored to the rigorous requirements of industrial fluid transmission, with the following key features:

1. Material Superiority: SS316/316L stainless steel contains molybdenum (2-3%), which enhances corrosion resistance against chlorides, acids, and alkalis—meeting ASTM A213 standards for seamless tubing. The material has a tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%, ensuring durability under high pressure and mechanical stress.
2. Precision Design: Fittings and connectors have precision-threaded ends (NPT, COMPR) with a thread tolerance of 2A/2B, ensuring tight, leak-proof connections. Seamless tubes have a smooth inner surface (surface roughness Ra ≤0.8 μm), reducing fluid friction and pressure loss by 15% compared to welded tubes.
3. Structural Integrity: Elbows and tees have a thickened wall design at the bend, increasing pressure-bearing capacity by 25% and preventing deformation under high pressure. Ball valves feature a full-port design, minimizing flow resistance, while check valves use FKM seals for enhanced leak-proof performance (leak rate ≤0.1 cc/min at 1000 psi).
4. Corrosion Protection: All parts undergo passivation treatment, forming a protective oxide layer on the surface, which improves corrosion resistance and meets ASTM A967 passivation standards. This treatment extends the service life of parts by 30% in corrosive environments.

2.4 Applicable Working Conditions

2.5 Maintenance & Care Recommendations

To extend the service life of the pipeline parts, reduce maintenance costs, and ensure the optimal performance of industrial fluid systems, the following practical maintenance recommendations are provided (tailored to industrial operational scenarios):

1. Routine Inspection: Conduct a monthly visual inspection of all parts to check for corrosion, leaks, or damage. For valves, test operation to ensure smooth opening and closing; for strainers (e.g., 510112), clean the mesh every 2 weeks to remove accumulated impurities and prevent clogging.
2. Regular Cleaning: Clean the inner surface of tubes and fittings annually using a non-corrosive cleaning agent (e.g., neutral detergent) to remove scale and deposits, maintaining smooth fluid flow. Avoid using abrasive cleaners that may damage the passivation layer.
3. Replacement Guidelines: Replace valves (e.g., ball valves, check valves) every 5-7 years or when leakage, jamming, or excessive wear is detected. Replace seamless tubes if corrosion thickness exceeds 10% of the wall thickness (e.g., 0.035″ wall tube: replace if corrosion ≥0.0035″).
4. Storage Conditions: Store unused parts in a dry, ventilated warehouse with a temperature of 0°C to +30°C and relative humidity ≤60%. Avoid direct sunlight, rain, and contact with corrosive substances (acids, alkalis). Store tubes in a horizontal position to prevent bending and deformation.
5. Installation Notes: When installing parts, use proper tools to tighten threaded connections (torque: 20-30 N·m for 1/2″ NPT, 30-40 N·m for 1″ NPT) to avoid over-tightening or under-tightening. Ensure alignment of tubes and fittings to prevent stress on joints, which can cause leaks. Use Teflon tape for threaded connections to enhance leak-proof performance.
