SUNHY: Integrated Piping & Connection Solutions
Material Documentation • Traceability • Application Review
Source piping components and fasteners against the exact drawing, standard, material, dimensions, service conditions, inspection plan and documentation requirements. Product capability and compliance are confirmed for each order scope before quotation.
Engineering the World’s Critical Connections.
From a local forge in 1988 to a global manufacturer today, Sunhy’shistory has been defined by precision and continual evolution.
Reliability starts with metallurgy. We manufacture to ASTM, DIN, and ISO standards using premium 304/316L stainless steel and select exotic alloys. This commitment to material integrity extends from our flanges and fittings to our industrial fasteners, ensuring exact chemical and mechanical performance across every joint in your process.
With strict control from raw material sourcing to final inspection, everybatch meets the same uncompromising standard-trusted by OEMs andengineering firms worldwide.
Quality Assurance
Documented Requirements for Every Connection.
Precision requires evidence. For flanges, fittings and high-strength fasteners, define the applicable standard or drawing, material, dimensions, coating, inspection, traceability and document package. Quality-system certificates, third-party reports and product approvals are supplied only when their legal entity, site, product and validity scope have been confirmed for the order.
Quality Documentation Review
Quality and certification evidence is reviewed against the supplying legal entity, manufacturing site, product scope and order requirements before it is referenced in a quotation.
Material Traceability
EN 10204 3.1 inspection documents may be requested for applicable products. Availability and content must be confirmed for the material, manufacturing route and specific order; one document does not establish universal coverage.
Global Compliance
Engineered to meet rigorous global codes including ASME, PED (EU), and JIS, ensuring seamless integration into international piping systems.
*As an INDURA® Approved Supplier, Sunhy has passed rigorous quality audits covering material traceability, dimensional accuracy, and delivery reliability.”
