EN 10216-5 1.4404 TP316L Seamless Pressure Tubing for Pressure Vessels and Heat Exchangers

EN 10216-5 is a harmonized European standard specifically for seamless stainless steel tubes for pressure equipment. Compliance with this standard is a prerequisite for products to comply with the EU Pressure Equipment Directive (PED 2014/68/EU). Obtaining EN 10216-5 certification serves as a technical passport for pipe products to enter and be distributed in the European market. Under this standard, the corresponding grade for TP316L is 1.4404.

Pressure tubing is specially designed, manufactured, and inspected for the safe conveyance of fluids or gases under pressure. Unlike conventional tubing, its production process involves stricter control over raw materials, manufacturing processes, and final testing to ensure structural integrity and leak-free operation under demanding conditions such as high temperature and pressure. It serves as a core safety component in the manufacture of equipment such as pressure vessels, boilers, and critical process piping.

Our EN 10216-5 standard pressure tubing is specifically designed for projects requiring compliance with the EU Pressure Equipment Directive (PED). It is widely used in the manufacture of pressure vessels, heat exchangers, industrial boilers, and complete piping systems for export to the European market. Whether used in the chemical, power, or oil and gas industries, selecting tubing that meets this standard is critical for ensuring your final equipment is successfully certified and enters the European market.

To ensure our products fully comply with EN 10216-5 and PED requirements, we implement comprehensive quality control and testing protocols. In addition to rigorous dimensional and visual inspections, each batch of tubes undergoes chemical composition analysis and mechanical testing (including tensile testing). Importantly, every pressure-bearing tube undergoes 100% non-destructive testing (eddy current or hydrostatic testing) to verify its integrity. All test results are recorded for full traceability and quality assurance.
