Services That Support Your Heat Exchangers & Boiler Tube Solution
We support your heat exchanger and boiler tube projects with structured engineering, controlled manufacturing processes, and inspection-based delivery to ensure performance, compliance, and installation reliability.
Working Conditions
We review operating temperature, pressure level, media type, and service life expectations to determine suitable tube materials and production standards.
Applicable Standards
We confirm required ASTM or ASME specifications early to ensure full compliance with project documentation and regulatory requirements.
Dimensional Requirements
We verify outer diameter, wall thickness, length, and tolerance ranges to avoid installation mismatch and unnecessary on-site modification.
Project Volume Planning
We evaluate total quantity and delivery phases to align manufacturing scheduling with your construction or maintenance timeline.
Material Selection
We recommend suitable carbon steel, alloy steel, stainless steel, or special alloys based on pressure, corrosion, and temperature conditions.
Mechanical Requirements
We confirm tensile strength, yield strength, and pressure resistance targets before production to meet boiler and heat exchanger performance needs.
Technical Drawing Review
We review project drawings to confirm bending radius, end preparation, and surface requirements before finalizing production planning.
Customization Scope
We define special processes such as finning, coating, or heat treatment to ensure technical clarity before manufacturing begins.
Sample Confirmation
If required, we provide sample tubes or technical data sheets for approval before mass production starts.
Process Confirmation
We confirm heat treatment, dimensional tolerances, and inspection scope with your engineering team before manufacturing.
Inspection Plan Alignment
We define required non-destructive testing or mechanical tests to align with project quality standards.
Final Specification Lock
All agreed parameters are documented and locked to prevent deviation during production.
Tube Forming
We produce seamless or welded tubes according to confirmed specifications and dimensional accuracy requirements.
Heat Treatment
We apply normalizing, annealing, or tempering processes to achieve required mechanical strength and stability.

Custom Heat Exchangers & Boilers Tube FAQs
Can you manufacture tubes according to our boiler or heat exchanger design code (ASME, EN, GB)?
Yes. We support ASME SA179/SA192/SA210/SA213, EN10216/10217, and GB standards, and can adjust mechanical properties and testing requirements to match your design code.
How do you ensure tube performance under high temperature and pressure?
We apply controlled heat treatment, hardness control, flattening/flare tests, and hydrostatic or eddy-current inspection to guarantee stability under thermal cycling and high-pressure loads.
Can you supply tubes already prepared for U-bending or finning?
Yes. We offer straight tubes, U-bent tubes (stress relieved), and tubes ready for external finning or internal grooving depending on the exchanger type.
What information do you need to confirm a custom order?
Medium type, working temperature/pressure, required standard, layout (straight/U-bend), tolerances, NDT requirements, and surface finish preference.
Do you provide anti-corrosion or anti-oxidation protection for shipping?
Yes. Tubes can be oiled, capped, wrapped, or packed in seaworthy crates with desiccants for long-distance transport or humid environments.
Can your tubes be matched with our existing tube sheets and headers?
Yes. We verify OD/WT tolerance, straightness, hardness, and end quality to ensure full compatibility with your existing exchanger or boiler design.
What is your typical lead time for large heat exchanger or boiler tube orders?
Most carbon steel and stainless steel tubes require 15–30 days, depending on the heat treatment, NDT level, and whether U-bending or additional processing is needed.
