Company & Factory Overview
Committed to quality and client satisfaction, we stand as a premier stainless steel pipe supplier in Jiangsu. Our 20,000-square-meter facility, outfitted with state-of-the-art equipment, boasts an annual production capacity of 5,000 tons. As a direct manufacturer, we bypass intermediaries to deliver competitive pricing, and also offer third-party transshipment services to help clients mitigate high tariff costs.
Factory Advantages:
Strict Quality Control: Rigorous testing covers every batch of duplex stainless pipe, from raw material to finished products, eliminating defects.
Complete Certifications: Hold ISO 9001, API 5L, and CE certificates, ensuring products meet international standards.
Stable Cost Control: Mature supply chain and large-scale production enable stable raw material sourcing and competitive pricing.
Flexible Customization: Provide tailored solutions to meet diverse order demands, supported by professional technical teams.
Quality Control
We hold a complete set of certificates and test reports, including material test certificates (MTC), inspection reports, and certification documents. Clients are welcome to visit our factory in person-we arrange professional guides to show our production lines, testing equipment, and warehouse, enabling face-to-face communication to address all concerns.
With reliable product quality, competitive prices, and thoughtful service, we have established long-term cooperative relationships with clients from over 30 countries, including the United States, Germany, Brazil, and Australia. Many clients choose to continue partnering with us after the first cooperation, a testament to their recognition of our brand.
Packaging & Logistics
To ensure the pipe arrives in perfect condition, we use customized packaging: seamless pipes are bundled with steel straps, while welded pipes are packed in wooden cases or pallets, with anti-rust oil applied to the surface. We cooperate with renowned logistics companies (DHL, FedEx, Maersk) to provide door-to-door service. For urgent orders, we offer expedited shipping, and for large batches, we arrange bulk shipping to reduce costs. We track the shipment in real-time and update clients promptly.
Pricing & Lead Time Advantages
Competitive & Transparent Prices: Our direct manufacturing model ensures our unit price is 10%-15% lower than that of trading companies. All prices are transparent, with no hidden costs-we provide detailed quotations including product specifications, quantity, price, and logistics fees.
Bulk Purchase Discounts: For orders exceeding 10 tons, we offer a 5%-8% discount; for annual contracts, we provide more favorable terms.
Controllable Delivery Time: Standard orders are delivered within 7-15 days, and customized orders within 20-30 days. We strictly abide by the delivery schedule and inform clients in advance of any potential delays, ensuring smooth production for our partners.
