Stainless Steel Tube Sheet Heat Exchanger Stainless Steel Fixed Tube Exchanger
Product Overview
We are a qualified pressure vessel manufacturer. The Cr-Mo Tube Sheet Heat Exchanger is a special heavy-duty industrial heat exchange equipment. Adopting chromium-molybdenum alloy steel as the raw material, it is designed to resist high temperature, high pressure and hydrogen embrittlement, widely used in hydrogenation and cracking industrial projects.
Product Description
The Cr-Mo Tube Sheet Heat Exchanger belongs to high-end heavy industrial heat exchange equipment. The shell, tube bundle, tube sheet and pressure-bearing accessories are all made of premium Cr-Mo alloy steel. It adopts integrated fixed welding structure with strict heat treatment process to eliminate internal welding stress.
This alloy steel material has excellent resistance to high-temperature hydrogen corrosion, creep resistance and mechanical stability. Optimized heavy-duty segmental baffles enhance structural compression resistance and fluid turbulence. All welding seams undergo 100% non-destructive testing. Each finished exchanger passes strict hydraulic test and air tightness inspection, solving material brittle fracture and corrosion failure of ordinary steel in harsh hydrogenation working conditions.

FAQ
Q: What is Cr-Mo steel heat exchanger used for?
A: It is a special heavy-duty heat exchange equipment for high-temperature, high-pressure and hydrogen-containing working conditions. It is mainly used in petrochemical hydrogenation, coal chemical cracking and heavy oil refining industries to resist hydrogen embrittlement and high-temperature creep.
Q: What is the difference between Cr-Mo steel and ordinary carbon steel?
A: Ordinary carbon steel is prone to hydrogen corrosion and brittle fracture under high temperature and hydrogen environment. Cr-Mo steel has stable alloy structure, excellent hydrogen corrosion resistance and high-temperature pressure resistance, suitable for extreme severe working conditions.
Q: Does Cr-Mo steel require special welding process?
A: Yes. All welds need preheating and post-weld heat treatment to eliminate welding stress. 100% NDT inspection is compulsory to ensure no welding defects and avoid structural cracking under high pressure.
Q: What temperature and pressure can this equipment withstand?
A: It can stably operate under the working pressure of 0.1MPa to 100MPa, and the sustainable working temperature ranges from 20℃ to 550℃, adapting to continuous high-temperature and high-pressure industrial circulation.
Q: What qualification documents can you provide?
A: Provide alloy steel material certificate, heat treatment report, NDT flaw detection report and hydraulic test report. 18-month warranty, with professional heavy industrial installation guidance and lifelong technical support.
