Power GenerationSuperheaters, reheaters, nuclear steam generatorsHigh-temperature steam at elevated pressure
Chemical ProcessingHigh-pressure reactors, synthesis gas coolersCorrosive media under high pressure
Hydrogen IndustryHydrogen coolers, heat exchangersHydrogen embrittlement resistance (Duplex)
Hydraulic SystemsOil coolers for high-pressure hydraulicsPressure spikes and fatigue resistance
AerospaceHeat exchangers for engine and hydraulic systemsExtreme reliability requirements
SubseaSubsea coolers, umbilical heat exchangersExternal hydrostatic pressure resistance
Why Choose High Pressure Heat Exchanger Tube?
AdvantageBenefit
Seamless constructionNo weld line weakness – maximum burst strength
Thick wall capabilityWithstands extreme internal pressures
High strength alloysDuplex and super duplex for pressure + corrosion
Thermal fatigue resistanceWithstands rapid temperature changes
NACE MR0175 complianceSuitable for sour service (H₂S environment)
Hydrostatic tested100% verified for leak-free performance
TraceabilityFull material traceability from melt to final tube
Design Considerations for High Pressure Tubes
FactorConsideration
Wall thicknessMust be calculated based on internal pressure (Barlow's formula)
Material selectionHigher strength alloys allow thinner walls at same pressure
Bend radiusU-bends require larger radii to avoid wall thinning
Thermal expansionMust be accommodated – U-tube design recommended
TestingHydrostatic or pneumatic testing required after fabrication

    Precision 301 304 316 430 Cold Rolled Stainless Steel Strip 2B BA No.4 Finish
    Precision cold rolled stainless steel strip is a narrow, thin-gauge stainless steel product manufactured to significantly tighter thickness and width tolerances than standard cold-rolled sheet. Unlike standard sheet (typically 1000mm or 1219mm wide), precision strip is produced in narrow widths — usually less than 600mm — and thin gauges from 0.05mm up to 3.0mm. The key differentiator is the tolerance : the precision strip holds thickness variations to as low as ±0.005mm,
