Forged Fittings Thread Pipe Nipple Incoloy 800H 1" SCH80 100mm Length Class 3000# ASME B16.11

1. Product Description

This product is a forged threaded pipe nipple manufactured from Incoloy 800H (UNS N08810) in accordance with ASME B16.11 standards . A pipe nipple is a short length of straight pipe with male threads on both ends, designed to connect two female-threaded fittings or pipe ends . Incoloy 800H is a nickel-iron-chromium alloy with controlled carbon content (0.05-0.10%) and a solution-annealed grain structure (ASTM 5 or coarser), providing significantly higher creep and rupture strength compared to standard alloy 800 . This 1" SCH80, Class 3000# fitting is designed for permanent threaded connections in high-temperature and corrosive service environments.

2. Key Product Parameters

3. Application / Usage

This threaded nipple is ideal for high-temperature and corrosive process systems:

• Petrochemical Processing: Furnace cracker tubes, pigtails, headers, convection and cracking tubes

• Power Generation: Steam superheater tubing, high-temperature heat exchangers, nuclear reactor components (HTR-PM)

• Chemical Processing: Nitric acid condensers, organic acid handling systems

• Heat Treatment Industry: Radiant tubes, muffles, retorts, furnace fixtures

• Concentrated Solar Power: High-temperature nitrate heat storage systems up to 650°C

4. Advantages

• Superior High-Temperature Strength: Controlled carbon content (0.05-0.10%) and solution annealing provide optimum creep and rupture properties above 500°C

• Excellent Oxidation Resistance: Forms a protective Cr₂O₃-SiO₂ oxide layer, resisting "microclimate reaction" and high-temperature corrosion

• Good Corrosion Resistance: Excellent resistance to nitric acid, organic acids, and stress corrosion cracking in aqueous environments; resistant to pitting and crevice corrosion

• Cost-Effective: Lower nickel content than Inconel alloys, offering a balance of performance and economy for high-temperature service

• Threaded Convenience: No welding required; fast installation, easy disassembly for maintenance

5. Functions

The pipe nipple provides a simple, reliable threaded connection between two female-threaded components (fittings, valves, or pipe ends). It serves as a transition piece in small-bore piping systems, enabling quick assembly, disassembly, and component replacement without welding operations.

6. Installation Instructions

1. Preparation: Clean pipe threads and fitting threads; remove all dirt, oil, and debris.

2. Thread Sealant: Apply Teflon tape or pipe dope to male threads to ensure a reliable seal.

3. Thread Engagement: Screw the nipple into the first female fitting by hand, then tighten with a wrench. Install the second fitting onto the opposite end.

4. Avoid Over-tightening: Do not exceed recommended torque to prevent cracking the fitting body.

7. Precautions

• Thread Compatibility: NPT, BSP, and BSPT threads are not interchangeable. Verify thread type per system specification .

• Temperature Limitation: For aqueous corrosion service, limit to approximately 500°C ; for dry atmospheres, higher temperatures are possible but verify system conditions.

• Creep Design: At elevated temperatures (>500°C), creep and rupture properties must be considered in system design .

• Pre-oxidation: In CSP applications, pre-oxidation treatment can enhance corrosion resistance .

8. Shipping & Delivery

• Standard delivery time is typically 15–30 days, subject to order quantity and specification availability.

9. Payment Terms

• Common international payment methods include T/T (Telegraphic Transfer) and L/C at sight (Letter of Credit) .

10. Packaging

• Products are securely packed in plywood cases or wooden crates with internal cushioning to ensure safe transportation and prevent damage during transit.

11. After-Sales / Return & Warranty Policy

• All products undergo strict quality inspection before shipment.

• In case of quality issues, retain original packaging and provide relevant photos or third-party inspection reports.

• Specific return, exchange, and warranty terms are subject to the final sales contract agreement.
