C&N industrial Group, pipe, fitting and flanges manufacturers,fbe epoxy and pe coating for pipeline since 1991,with brand C&N huitong ,C&N hongcheng.
Recently, C&N custom-produced ASTM A815 WP S32205 duplex stainless steel tee fittings for a client in Dammam, Saudi Arabia. After completing all factory inspections and professional packaging, the fittings were successfully shipped by sea to the designated port. These butt-weld tees, which comply with ASME B16.9 standards, were specially designed for the region’s demanding petrochemical and energy pipeline systems. The entire process, from precise order management to high-quality delivery, showcases efficient collaboration and marks a new stage in the partnership between both parties in the high-end pipeline fittings sector.
Key Processes and Inspection: The product undergoes rigorous PMI (Positive Material Identification) spectroscopic testing to ensure that crucial alloy elements (Cr, Ni, Mo, etc.) fully meet the standards, guaranteeing the authenticity and uniformity of the material.
Application Areas: Pipeline systems for transporting highly corrosive media in the petrochemical, chemical, and energy industries.
Key deliverables include:
Material Test Certificate (MTC) in accordance with EN 10204 3.1: Clearly indicating the product as “ASTM A815/A815M WP S32205 (2205)” and listing the actual chemical composition, mechanical test results, and heat treatment status, signed by an independent authorized representative.
Non-Destructive Testing (NDT) Reports: such as PT and RT reports, issued by certified personnel.
Dimensional Inspection Report: Certifying that the product meets the dimensional tolerance requirements of ASME B16.9.
Certificate of Origin, Commercial Invoice, Packing List, and Bill of Lading: a full set of customs and logistics documents.
Product Identification and Traceability Documents: Ensuring the product stamp (including standard number, material grade, heat number, etc.) corresponds fully with all documentation, enabling complete lifecycle traceability.
In terms of certification and compliance, our duplex steel product manufacturing system meets ISO 9001 standards, and the products comply with material requirements of process piping codes such as ASME B31.3. For projects that require it, we can provide:
CE Marking and PED 2014/68/EU Declaration of Conformity (if applicable): Demonstrating that the product meets the EU Pressure Equipment Directive.
Compliance Statements for Specific Projects or Clients: Confirming that the product fully meets all special requirements outlined in their technical specification (ITP).
