Frequently Asked Questions (FAQ)
Professional Piping Solutions
Q1: What are the primary differences between Reinforced PAMC Pipes and Nylon-Steel Composite Pipes?
A: * Reinforced PAMC Pipe: A high-performance engineering plastic pipe known for its exceptional corrosion resistance, lightweight nature, and smooth internal surface (low hydraulic friction). It is ideal for environments involving strong alkalis and weak acids where traditional metal pipes fail.
·
Nylon-Steel Composite Pipe: This series integrates the chemical resilience of nylon with the mechanical strength of steel. Designed for high-pressure (up to 4.0 MPa) and high-temperature (up to 160°C) applications, it is the preferred choice for long-distance oil and gas transmission or mining slurry discharge.
Q2: What is the operating temperature range for your piping systems?
A: Our products are engineered for extreme environments:
·
Reinforced PAMC Pipe: -36°C to 150°C
·
Nylon-Steel Composite Pipe: -36°C to 160°C
·
Our pipes maintain their structural integrity and impact resistance even in sub-zero Arctic conditions.
Q3: How do your pipes perform against chemical corrosion and wear?
A: Our pipes offer superior resistance in several areas:
·
Chemical Resistance: Highly resistant to alkalis (e.g., <20% NaOH), ammonia, seawater, and most inorganic salts. They are also inert to hydrocarbons like gasoline, diesel, and mineral oils.
·
Abrasion Resistance: The nylon lining’s wear resistance is 2–3 times higher than that of carbon steel. Its self-lubricating properties also result in significantly lower pressure drops, reducing pumping energy costs.
Q4: What are the maximum sizes and connection types available?
A: We specialize in large-scale solutions, with diameters reaching up to DN2000mm and pressure ratings from 1.0 to 4.0 MPa.
·
Standard Connection: Integrated flange connection for easy, bolt-on installation (no welding required on-site).
·
·
Alternative: Thermal fusion welding is available for specific pure nylon piping projects.
Industry Applications
Q1: Which industries benefit most from your products?
A: Our piping series is widely utilized in:
·
Energy Sector: Oil & gas gathering, water injection, and brine transport.
·
Chemical Processing: Soda ash, chlor-alkali, salt, and phosphorus chemical production.
·
Mining: Transport of abrasive slurries and tailings.
·
Municipal & Infrastructure: Large-scale water supply, drainage, and desalination plants.
Q2: Do buried pipelines require additional anti-corrosion coating?
A: PAMC pipes are naturally corrosion-resistant and require no extra coating. For Nylon-Steel Composite Pipes, we apply external protection such as epoxy resin with fiberglass reinforcement (or 3PE coating) based on soil conditions to ensure a long service life.
Ordering & Customization (OEM/ODM)
Q1: Do you accept OEM or custom specifications?
A: Yes. As an original manufacturer with over 100 sets of specialized equipment, we can customize pipe length, wall thickness, and pressure ratings according to your technical drawings.
Q2: What is your Minimum Order Quantity (MOQ)?
A: * Stock Items: Flexible MOQ for standard sizes to support trial orders.
·
Custom/Large Diameter: Determined based on production scheduling and raw material requirements. Please contact our sales team for a specific quote.
Q3: What is the typical lead time for an order?
A: * Standard Specifications: 15–25 working days.
·
Large Diameter (Above DN600) or High Pressure: 25–40 working days.
·
Exact delivery dates are confirmed at the time of contract signing.
Quality Assurance & Technical Support
Q1: What certifications does your company hold?
A: * Systems: ISO 9001 (Quality), ISO 14001 (Environment), and ISO 45001 (Health & Safety).
·
Standards: We are a key drafter of Chinese National/Industry Standards for the oil and gas sector (e.g., SY/T 6701, CJ/T 438).
·
Compliance: Our products hold Special Equipment Manufacturing Licenses and various Classification Society certifications for marine use.
Q2: What is the expected service life of your pipes?
A: Under recommended operating conditions, our piping systems are designed for a service life of 10+ years, significantly outlasting traditional metal pipes in corrosive or abrasive environments.
Q3: Do you provide on-site installation guidance?
A: Yes. We offer detailed installation manuals and video tutorials.
Logistics & Global Trade
Q1: What are your accepted payment and trade terms?
A: * Trade Terms: EXW, FOB, CIF, CFR.
·
Payment: Standard T/T (Telegraphic Transfer). Typically 30% deposit upon order, with the remaining 70% balance due before shipment or against inspection documents.
Q2: How are pipes packaged for international sea freight?
A: We ensure maximum protection for long-distance transit:
·
End Protection: Heavy-duty caps to protect flange faces and prevent internal contamination.
·
Securing: Pipes are loaded using specialized cradles or frames to prevent shifting and impact.
·
Container Optimization: We recommend standard lengths (e.g., 3m or 6m) to maximize container space and reduce shipping costs.
