This EN 10216-4 1.0453 seamless steel tube specification belongs to the European standard suite for seamless steel tubes intended for pressure purposes, specifically formulated for operation under reduced temperature conditions. Unlike common ASTM carbon steel pipe grades, EN 10216-4 defines strict toughness criteria to guard against brittle fracture, a key concern for outdoor and utility piping systems in Singapore that can experience sharp temperature shifts during rainy seasons. Our production team maintains tight wall thickness control to keep the 3.6 mm and 4.5 mm nominal thickness within the tolerance range required by the standard.
We supply this EN 10216-4 1.0453 seamless steel tube in 48.3 mm outer diameter with 3.6 mm wall, and 114.3 mm outer diameter with 4.5 mm wall. The clear varnish coating provides a thin temporary protective layer during sea freight and storage, without obscuring the tube marking. Each length is also marked with grey RAL-7001 colour bands, a simple but effective method that helps site crews quickly separate these low-temperature tubes from other carbon steel pipe stocks on the fabrication yard. This colour coding reduces the risk of mix-up when spooling multiple material batches side by side.
QC checks cover OD roundness, wall thickness, surface finish and the integrity of the clear varnish layer before packing. All test documents including material certificates, impact test records and dimensional reports are compiled following European pressure equipment requirements. Many Singapore EPC contractors combine EN pressure piping components with ASME fittings and flanges, so we make sure all documentation is structured for easy review by local third-party inspectors.
Haihao Group stocks and fabricates EN 10216 series seamless pressure tubes, including grade 1.0453 for low temperature applications, for clients across Singapore and Southeast Asia. We offer custom cutting, bevelling, protective coating and project-specific colour band marking according to client paint codes. If you need European-standard seamless pressure tubes for low-temperature piping projects, send your OD, wall thickness and marking requirements for a quotation.
