Galvanized Nipples Koxy Galvanized Equal Nipple (FIG.280) is a high-performance pipeline connector made of premium malleable iron with hot-dip galvanized finish. Compliant with EN10242/ANSI/ASME B16.3 standards, it supports PN25 (2.5MPa) working pressure and 200°C maximum temperature, ideal for water, oil, gas and petrochemical pipeline systems. With precise threading (EN10226/ASME B1.20.1), it ensures pressure-tight connections and easy installation, suitable for steel/cast iron pipeline assembly in industrial, commercial and municipal projects.
Functional Advantages Threaded Versatility: Enable the creation of custom pipeline configurations (straight, branched, or angled) via threaded connections, adapting to project-specific requirements.
Corrosion Resistance: Hot-dip galvanized finish provides long-term protection against rust and chemical erosion, ensuring reliability in harsh environments.
Structural Integrity: Manufactured from high-strength malleable iron, compliant with tensile strength (350MPa) and hardness (HB150) standards for high-pressure systems (up to 25BAR).

Application Scope
Certificates We implement a 4-step quality control (QC) process throughout production:
Incoming material inspection: Test steel plates/forgings for chemical composition and mechanical properties (e.g., tensile strength);
In-process testing: For pipes (hydrostatic pressure test), valves (leakage test at 1.5x rated pressure), fire hydrants (flow rate test);
Final inspection: Check dimensions, surface finish, and certification compliance;
Third-party audit: We accept inspections by SGS, BV, or your designated QC team before shipment.
All products come with a 12-24 month warranty (varies by product type) against manufacturing defects.
Our one-stop service covers the entire project lifecycle to save your time and costs:
Pre-sales: Technical consultation (e.g., selecting the right pipe material for corrosive environments, valve type for high-temperature systems);
Supply: Integrated product bundles (e.g., fire pipeline + fittings + valves + sprinklers) with unified specifications;
After-sales: Installation guidance (video tutorials or on-site support if needed), maintenance training, and replacement of defective parts;
Documentation: Unified shipping documents (commercial invoice, packing list, certificate of origin) to simplify customs clearance.
We offer flexible and secure payment terms tailored to international trade, including options for full payment and advance payment based on cooperation scenarios:
General scenario: Full payment acceptance
For most orders (e.g., new client first cooperation, standard product orders ≤$30,000), we accept full payment before shipment. This can be done via:
T/T (Telegraphic Transfer): 100% full payment to our designated bank account;
PayPal/Western Union: 100% full payment for small orders (≤$5,000) or sample orders.
Specific scenarios: Advance payment available
For specific cooperation cases, we support advance payment (partial prepayment) to reduce your upfront capital pressure, including:
Long-term cooperative clients (with 2+ successful previous orders): Advance payment of 30%-50%, and the remaining balance before shipment (via T/T);
Large orders (≥$50,000) or customized product orders (e.g., non-standard fire pipelines, special-pressure valves): Advance payment of 40%-60% (to cover raw material costs), and the remaining balance after production inspection but before shipment (via T/T or L/C);
Government/engineering project orders (with official procurement contracts): Advance payment of 20%-30% (subject to contract negotiation), and the remaining balance in installments based on shipment progress.
Other secure terms
L/C (Letter of Credit): Irrevocable L/C at sight issued by a first-class bank (available for both full payment and partial advance payment, preferred for large orders ≥$50,000);
Credit terms: 30-60 days credit for long-term trusted clients (after 3+ successful orders and credit verification, applicable to regular repeat orders).
Absolutely. As a one-stop supplier, we specialize in customizing products to match your unique project needs:
Customizable parameters: Pipe diameter (DN15-DN2000), valve pressure rating (PN10-PN400), material (304/316 stainless steel, carbon steel, galvanized steel);
Fire system customization: We collaborate with your engineers to design integrated systems (e.g., high-rise building fire pipelines + matching valves + sprinklers) and provide 2D/3D drawings for confirmation before production.
Sample production is available for testing prior to mass orders.
