Frequently Asked Questions
What is a titanium heat exchanger?
A heat transfer device engineered from high-grade titanium (Grade 2 / TA2) for efficient heat exchange in harsh industrial environments. Titanium provides superior corrosion resistance — particularly in seawater and chloride media — along with excellent thermal conductivity and a service life exceeding 20 years.
Why choose titanium over stainless steel or CuNi?
Titanium provides exceptional corrosion resistance in seawater and chloride environments where 316L stainless steel fails due to pitting and crevice corrosion. Compared to CuNi 70/30, titanium is immune to erosion-corrosion, has a higher strength-to-weight ratio (45% lighter than steel), and lasts significantly longer — often 20+ years without tube replacement.
What temperature and pressure range is supported?
Lmart's Ti heat exchangers support an operating temperature range from −163 °C (cryogenic ethylene service) to 185 °C, and design pressures from −0.1 MPa (vacuum) to 3.3 MPa. For higher pressures or temperatures, consult our engineering team for custom configurations.
What industries use Ti heat exchangers?
Primary industries include marine (LPG/NH₃/Ethylene gas carriers, offshore platforms), chemical processing (chlor-alkali, acid handling), petroleum refining (overhead condensers, sour water coolers), and power generation (seawater-cooled surface condensers). Lmart's largest volume is marine cargo heating and condensing systems.
Can these heat exchangers handle seawater applications?
Absolutely. Titanium's inherent oxide layer makes it virtually immune to seawater corrosion. Lmart has delivered 110+ titanium units for marine cargo heating systems to Wärtsilä and TGE Marine, operating in seawater-cooled circuits on LPG carriers worldwide.
What certifications do Lmart's Ti heat exchangers hold?
ASME U stamps, PED 2014/68/EU (CE marking), and marine classification from DNV, ABS, BV, LR, NK, KR, and CCS. Quality systems certified to ISO 9001, ISO 14001, and ISO 45001. Each unit is delivered with full class survey documentation.
How long does a titanium heat exchanger last?
With proper maintenance, titanium heat exchangers routinely exceed 20 years of service — significantly longer than carbon steel (5–10 years) or CuNi (10–15 years) in seawater environments. The superior longevity offsets the higher initial material cost through reduced replacement and downtime.
What maintenance do Ti heat exchangers require?
Regular inspection for fouling (marine growth on seawater side), periodic cleaning of tube bundles, and routine checks for gasket and seal integrity. Titanium tubes themselves require minimal maintenance — no coating, no cathodic protection, and no scheduled tube replacement under normal operating conditions.
Is customization available for specific applications?
Yes. Lmart provides fully customized designs including shell diameters from DN400 to DN890+, tube lengths up to 7,060 mm, and configurations tailored to specific thermal duties. Our engineering team works from customer process datasheets to optimize U-values and pressure drop.
Do Ti heat exchangers offer energy savings?
Yes. Titanium's high thermal conductivity (21.9 W/m·K) and resistance to fouling maintain high U-values throughout the service life. This translates to smaller required heat transfer area, lower pumping energy, and reduced energy consumption compared to fouling-prone alternatives.
What is the typical lead time?
Standard marine Ti heat exchangers: 14–18 weeks from approved-for-manufacture drawings. For multiple units on a series build (e.g., TGE Marine fleet orders), lead time is optimized through batch production. Exact delivery confirmed at contract award based on titanium plate/tube procurement lead time.
