Hebei All Trust Steel Co., Ltd manufactures premium astm a213 boiler tube solutions engineered for extreme thermal and mechanical stress environments. We have more than 15,000 tons of yearly manufacturing capacity, and all of our seamless boiler tubes are tested 100% hydraulically. All of our seamless boiler tubes conform to strict ASTM A213/ASME SA213 criteria. Each tube is 100% eddy current tested and mill test certified (EN 10204 3.1/3.2) for proven dependability in power generation, petrochemical processing and industrial heat recovery applications where system integrity is non-negotiable.

Power plant operators and process engineers permanently have to deal with thermal stress absorption, steam-side oxidation and lengthy creep deformation. Our seamless tube production minimises the possibility of weld-line failures that might threaten pressure containment.
Hot solid-billet extrusion method yields consistent cross sections of cylinders. This structural uniformity guaranties uniform thermal expansion across the whole boiler network. You save the expense of downtime from premature tube failure.
Each batch of manufacture undergoes a solution annealing procedure at controlled temperatures. This metallurgical procedure optimises the grain size distribution for long-term mechanical performance. Your superheater parts retain dimensional stability over long-term exposure to subcritical and supercritical steam conditions.
Our acid-pickled and passivated surface treatment ensures maximum heat transfer efficiency. Clean interior surfaces avoid the accumulation of scale which lowers heat conductivity and increases localised corrosion.

Grades TP304H / TP316H / TP321H / TP347H are highly carbonised for better creep-rupture strength. These ‘H’ grades are significantly superior than the ordinary or low carbon grades in resisting thermal stress deformation if your boiler runs continuously at temperatures over 525°C.
TP304 is a dependable choice for oxidation resistance in moderate temperature superheater areas. This grade is a compromise between economy and sufficient corrosion protection for steam pressures up to 10 MPa.
Molybdenum is added to TP316 to improve pitting resistance in brackish water condensers and coastal power facilities. The alloying element added gives protection against stress corrosion cracking by chlorides.
TP321 and TP347 have titanium or niobium stabilisers. These properties help to avoid intergranular corrosion in heat affected zones after welding and are hence appropriate for manufactured boiler assemblies.
Though our primary focus is austenitic grades, we coordinate supply of T11, T22, and T91 ferritic grades for specific high-temperature applications requiring different thermal expansion characteristics.

Your superheater and reheater sections demand materials that maintain mechanical integrity under continuous steam temperatures reaching 620°C. Our astm a213 boiler tube solutions in Grade TP347H deliver the creep resistance necessary for these extreme operating parameters.
The seamless structure prevents longitudinal stress concentration points. This manufacturing advantage translates directly into extended service intervals and reduced maintenance costs.
Tubes for heat exchanger bundles treating volatile hydrocarbons must have resistance to hydrogen attack and sulfidation concurrently. TP316L grades provide you the corrosion barrier you require, without sacrificing thermal conductivity.
We cold-draw to a precision that yields wall thickness tolerances of ±0.05 mm. This dimensional precision provides for correct tube-to-tubesheet rolling and leak-free junctions throughout your heat recovery network.
HRSG installations face thermal cycling that accelerates fatigue failures in inferior materials. The regulated solution annealing treatment we apply creates a stable microstructure that absorbs repeated thermal shock.
You benefit from predictable performance across thousands of heating-cooling cycles. Your waste heat recovery system maintains efficiency targets without unplanned shutdowns.

Eddy Current Testing finds longitudinal and transverse surface defects of 0.3 mm. This automated inspection system performs at production speeds while maintaining the sensitivity requirements of the ASME regulations.
Ultrasonic Testing identifies internal discontinuities that could propagate under cyclic stress. Every tube above 25 mm outer diameter receives full-body UT examination before shipment.
Hydrostatic Testing proves pressure containment capability at 1.5 times your design working pressure. This destructive pressure proof test eliminates weak specimens before installation.
Flaring Tests expand tube ends to specified diameters, confirming ductility and freedom from concealed cracks. This validation is particularly critical for tubes destined for roller expansion joints.
Flattening Tests compress tube sections between parallel plates, demonstrating adequate plasticity without splitting. You receive material capable of withstanding installation stresses without brittle failure.
Hardness Testing (Rockwell or Brinell) verifies proper heat treatment completion. Results within specified ranges indicate correct grain structure formation for long-term creep resistance.
We manufacture tubes matching your exact furnace and boiler layouts. Custom outer diameters, wall thicknesses, and fixed-length cutting eliminate field modifications that compromise material integrity.
Standard nominal sizes stock immediately for quick turnaround. Specialized dimensions enter production within 15-20 days through our priority scheduling system.
Bright Annealed (BA) finishes provide mirror-smooth internal surfaces for applications where flow resistance must be minimized. The reduced surface roughness improves steam velocity distribution.
Mechanical Polishing achieves specified Ra values for critical heat transfer zones. Controlled surface texture enhances nucleate boiling efficiency in evaporator sections.
The multi-pass welded joints are precisely bevelled as per ASME B16.25. Our CNC machining centres can hold compound angles to ±0.5°, simplifying your manufacturing process.
Square-cut plain ends receive thorough deburring and cleaning. You avoid contamination issues during installation and commission hydrostatic testing.
Our export packing solution is designed to preserve your investment throughout international transportation. Heavy quality waterproof wrapping and plastic end protectors prevent surface damage and moisture penetration, while fumigation-free timber containers are used.
Flexible logistics routeing is possible via strategic shipping from the ports of Shanghai, Ningbo, Tianjin and Qingdao. We can provide FOB, CFR, CIF and DDP terms according on your purchase desire.
Technical support extends throughout your project lifecycle. Our engineering team provides material selection guidance, corrosion resistance analysis, and container loading optimization to maximize shipping efficiency.
