Product Overview

This custom tubular shell and tube heat exchanger supports flexible material matching for shell side and tube‑side. Users may select carbon‑steel / SS304 / SS316 for shell housing; tube bundles and tubesheets can be configured in SS304, SS316, TA1, TA2 titanium or phenolic‑resin impregnated impermeable graphite according to medium corrosivenessMersen.

Metal versions (stainless steel & titanium) adopt high‑quality seamless heat‑exchanger tubes, precision tube‑to‑tubesheet welding; graphite units use cemented tube‑tubesheet joint technology for reliable anti‑leak performance. It completes heat transfer between two fluids through partition wall conduction. Different material combinations solve diversified working scenarios: stainless steel for general corrosion, titanium for seawater / chloride environment, graphite for strong acid media which metal materials cannot withstand. It serves as heater, cooler, condenser and evaporator for process industries worldwide.

Material Grade Characteristics

Carbon Steel / SS 304 / SS 316

• 304: General‑purpose austenitic stainless steel, good resistance to weak corrosion media, suitable for food, water and low‑corrosion chemical fluid
• 316: Molybdenum‑containing grade, improved pitting & crevice corrosion resistance for moderate chloride‑containing process, pharmaceutical sanitary service
• Carbon Steel: Cost‑effective shell material for non‑corrosive shell‑side medium.

Titanium TA1 / TA2 (Commercially Pure Titanium)

• Excellent corrosion resistance in seawater, brine, wet chlorine and many salt solutions; immune to chloride stress corrosion cracking
• High specific strength, smooth surface reduces fouling deposition, stable mechanical performance below 315℃ long‑term operationTsisco
• Reliable weldability for tube bundle fabrication; widely used for marine, desalination and sour chemical cooling loops.

Resin‑Impregnated Tubular Graphite

• Phenolic resin impregnated impermeable graphite, excellent thermal conductivity (50‑120 W/m·K)SGL Carbon
• Outstanding resistance to hydrochloric acid, phosphoric acid, most non‑oxidizing acids and organic solvents; not suitable for strong oxidizing media and strong alkali at high temperature
• Anti‑scaling property, stable thermal shock performance, ideal for strong acid heating / condensation process where metal material failsMade-in-Ch....
