Introduction to Material Selection Advantages and Application of Titanium Plate for Head of Titanium Heat Exchanger

The head of heat exchanger is the core pressure-bearing component of heat exchange equipment such as chemical, caustic soda and seawater desalination equipment, which is subject to high temperature and high pressure, acid and alkali corrosion and medium scouring for a long time. Material selection directly determines the service life and operation safety of the equipment. Traditional carbon steel and stainless steel heads are easy to suffer from corrosion, leakage, deformation and damage, and titanium plates become special core materials for titanium heat exchanger heads due to their light weight, high strength, good corrosion resistance and easy stamping and welding.

The head of the heat exchanger is a kind of bended stamping part, which has high requirements on the plasticity, toughness and uniformity of the plate. The industry mainstream uses TA2 (Gr2) industrial pure titanium plate, with balanced material performance, excellent welding performance, no cracking or peeling during stamping forming, perfect adaptation to elliptical head, dished head and spherical head processing technology, stable resistance to strong alkali, chloride ion and other corrosive media, and elimination of head corrosion perforation, weld failure and other failures. It is the standard material for heat exchanger head. TA3 titanium plate can be selected under high pressure and strong corrosion conditions, with better strength and corrosion resistance.

Most of the special titanium plates for heads are cold rolled and annealed, with a common thickness of 2.0mm - 12mm. The plates have flat surface and uniform thickness. The surface is subject to pickling treatment, and are suitable for various head spinning and die pressing. Products strictly comply with GB3621 and ASTM B265 standards, with stable material composition, no impurities, no sand holes, excellent sealing and pressure resistance after forming, greatly reducing equipment operation and maintenance costs.

Shaanxi Shenyi Tuoda Technology Co., Ltd. specializes in supplying special TA2 and TA3 titanium plates for heat exchanger heads, with complete stock specifications, and supports fixed cutting and customized processing. The plate is applicable to all kinds of head processing processes, with good molding effect and strong corrosion resistance. It is widely matched with titanium heat exchanger equipment in chemical and energy industries, with reliable quality and stable supply.
