Optimizing Multi-Pressure Threaded Pipelines: Haihao Group Supplies Dual-Material Threaded Fittings to Ivory Coast
Managing piping networks across industrial, marine, and utility infrastructures in West Africa requires precise matching of fitting metallurgy to fluid aggressiveness and pressure ratings. While high-pressure process loops and chemical dosing manifolds demand high-purity corrosion resistance, utility air and general water supply lines rely on cost-effective, durable galvanization. Addressing these diverse operational requirements, Haihao Group has completed manufacturing, NPT thread gauging, pressure testing, and container dispatch for a comprehensive multi-material consignment supplied to an industrial engineering customer in Ivory Coast.
This export shipment integrates two complete series of precision NPT threaded fittings: heavy-duty 1000 psi Class 316 stainless steel components alongside reliable 150 psi hot-dipped galvanized (HDG) carbon steel fittings.
Consignment Order Matrix: Dual-Pressure & Dual-Material Range
To support instrumentation, branching, and piping size reductions across the client’s facility in Ivory Coast, the shipment covers an extensive assortment of hex nipples, hex couplings, reducing bushings, equal tees, and elbows:
| Component Type | Size Range | Pressure Rating | Material Grade | Thread Profile | Primary Service Application |
| Hex Nipple (Male x Male) | 1/8” to 3/4” | 1000 psi / 150 psi | ASTM A276 SS316 / HDG Steel | NPT Male x Male | High-pressure & utility line jointing |
| Hex Reducing Bushing | 1/2” x 1/4” to 1” x 3/4” | 1000 psi / 150 psi | ASTM A276 SS316 / HDG Steel | NPT Male x Female | Inline line-size reduction points |
| Full Hex Coupling | 1/8” to 2” | 1000 psi / 150 psi | ASTM A276 SS316 / HDG Steel | NPT Female x Female | High-torque straight pipe joining |
| Equal Female Tee | 1/4” to 1″ | 1000 psi/ 150 psi | ASTM A276 SS316 / HDG Steel | NPT Female (3 Ends) | Instrument & utility branch take-offs |
| 90° Female Elbow | 1/2” | 150 psi | Hot Dipped Galvanized Steel | NPT Female x Female | Utility fluid directional change |
Metallurgical Integrity: SS316 Corrosion Resistance & Heavy-Duty Galvanized Protection
Procuring small-bore threaded fittings through a certified 1000 psi SS316 NPT fitting supplier eliminates risks of thread galling, seal blowout, or premature atmospheric rusting under humid tropical conditions.
Haihao Group enforces strict manufacturing controls across both material options:
High-Pressure Molybdenum-Stabilized Stainless Steel: Machined from bar-stock ASTM A276 SS316, the 1000 psi series handles aggressive media, saltwater exposure, and severe process pressures. The 2.0- 3.0% molybdenum content prevents pitting corrosion in coastal West African environments.
Hot-Dipped Galvanized Surface Defense: The 150 psi carbon steel line undergoes hot-dip galvanizing, depositing a thick zinc-iron alloy barrier that seals the metal against ambient humidity and general utility water corrosion.
Precision CNC NPT Thread Profiles: All male and female threads conform strictly to ANSI/ASME B1.20.1. Taper angles and thread depths are CNC-machined to ensure proper thread engagement and leak-free sealant distribution without cracking fitting bodies during wrench tightening.

Strict Quality Inspection, Thread Gauging & Export Packaging
To uphold our reputation as a trusted 1000 psi SS316 NPT fitting supplier, every fitting in this dual-material batch passed stringent quality protocols before shipment:
100% Thread Gauge Verification: Calibrated L1 and L2 NPT plug and ring gauges verified all male nipples, female couplings, reducing bushings, and tees for perfect thread pitch and taper alignment.
Pressure Proof Testing: Hydrostatic and pneumatic shell testing confirmed structural integrity at 1.5 x rated working pressure (1500 psi for SS316 and 225 psi for HDG items).
Rust Prevention & Protective Capping: Stainless items received solvent cleaning and passivation, while HDG items were treated with rust-inhibiting oils. Threads were fitted with protective plastic caps to prevent transport damage.
Complete Certification Package: Supplied with EN 10204 3.1 Mill Test Certificates detailing chemical heat analysis, mechanical yield/tensile strength, coating thickness logs, and pressure test verification.
Partnering with an experienced 1000 psi SS316 NPT fitting supplier ensures smooth field fit-up, zero thread binding, and long-term operational safety across high-pressure and utility networks.
