Product Overview
High‑pressure Boiler Tube is special seamless pipe for core pressure‑bearing parts of power station and industrial boilers. This High‑pressure Boiler Tube is developed for harsh high‑temperature, high‑pressure and alternating thermal load conditions. High‑pressure Seamless Boiler Tube, as mainstream type of High‑pressure Boiler Tube, adopts integral rolling without welding seam to avoid crack and leakage risk. High‑temp High‑pressure Boiler Tube, upgraded version of High‑pressure Boiler Tube, is applied for supercritical and sub‑critical boiler superheater and reheater components.
Ordinary seamless steel tube cannot resist long‑term high‑temperature creep and cyclic pressure. High‑pressure Boiler Tube strictly controls sulfur and phosphorus impurities with high rupture strength and good oxidation resistance. High‑pressure Seamless Boiler Tube owns uniform metallographic structure and excellent thermal‑fatigue resistance for continuous long‑time operation. Optimized by heat treatment, High‑temp High‑pressure Boiler Tube resists deformation under extreme high‑temperature service. All our High‑pressure Boiler Tube, High‑pressure Seamless Boiler Tube and High‑temp High‑pressure Boiler Tube pass piece‑by‑piece hydrostatic test and NDT inspection to guarantee safe boiler operation.

Manufacturing & Delivery Condition
High‑pressure Boiler Tube is produced by clean steel smelting, hot rolling, hot extrusion, cold drawing and cold rolling. Carbon steel High‑pressure Boiler Tube is normalized for delivery. Alloy grade High‑pressure Seamless Boiler Tube is normalized & tempered. Heat‑resistant High‑temp High‑pressure Boiler Tube must be normalized and tempered to improve creep‑resistance performance.
Every outgoing High‑pressure Boiler Tube passes hydrostatic test, UT ultrasonic test and ET eddy‑current test. Each batch of High‑pressure Seamless Boiler Tube and High‑temp High‑pressure Boiler Tube can provide EN10204‑3.1/3.2 certificate, SGS/BV third‑party inspection acceptable.
Advantages
Reliable performance under harsh conditions: High‑pressure Boiler Tube features high high‑temperature rupture strength against pressure fluctuation; High‑pressure Seamless Boiler Tube eliminates weld‑failure risk; High‑temp High‑pressure Boiler Tube provides outstanding oxidation & creep resistance for super‑critical boilers.
Good welding & processing property: Our High‑pressure Boiler Tube has controlled carbon equivalent, easy for cutting and bending, improve boiler manufacturing efficiency.
Strict quality management: Full‑process inspection from steel‑making to NDT. Samples reserved for each High‑pressure Seamless Boiler Tube and High‑temp High‑pressure Boiler Tube.
Stable supply: Mass stock of High‑pressure Boiler Tube, customized rolling for large OD, heavy wall and special alloy grades.
Application
High‑pressure Boiler Tube widely used in thermal power and energy equipment. Different grades of High‑pressure Seamless Boiler Tube and High‑temp High‑pressure Boiler Tube match various working conditions. In power plant industry, High‑pressure Boiler Tube applies for boiler water‑wall, economizer, superheater, reheater, header and main steam pipeline; for industrial high‑pressure steam boilers, High‑pressure Seamless Boiler Tube serves as heating surface tubes; in coal‑chemical & petrochemical sector, High‑temp High‑pressure Boiler Tube is used for waste‑heat boiler and high‑temperature heat‑exchange pipeline; High‑pressure Boiler Tube also works for thermal power generating sets and high‑pressure heat‑exchange equipment.
