super efficiency immersion spiral stainless steel pipe coil cooler for water tank heat transfer

Stainless steel SUS304,SUS316 heat exchanger (Immersion type) :

APT engineers will select different materials according to the working conditions of your heat exchanger, develop appropriate processing technology, and inform our customers of the correct use and maintenance methods, so as to ensure that stainless steel will not produce corrosion, pitting, rust or wear. Our different types of stainless steel heat exchangers are well used in industrial corrosion environment without chloride, marine environment, acidic water, saline water and chemical corrosion environment.

How to choose the right material for shell or tube of heat exchanger:

304 is a versatile stainless steel, which is widely used in the production of equipment and components requiring good comprehensive performance (corrosion resistance and formability), which is also the most commonly used heat exchange material in APT.

304L is a variant of 304 stainless steel with low carbon content. It is used for welding occasions. Lower carbon content minimizes the amount of carbides precipitated in the heat affected zone near the weld, and the precipitation of carbides may lead to intergranular corrosion (welding corrosion) of stainless steel in some environments.

304N is a nitrogen-containing stainless steel. Nitrogen is added to improve the strength of the steel.

308 stainless steel is used to make welding rods.

The 316 and 317 stainless steels contain aluminium, so their pitting corrosion resistance in marine and chemical environment is much better than 304 stainless steels. Among them, 316 stainless steel includes low carbon stainless steel 316L, high strength stainless steel 316N containing nitrogen and free cutting stainless steel 316F with high sulphur content.

321, 347 and 348 stainless steel stabilized by titanium, niobium and tantalum, respectively, are suitable for high temperature welding components. 348 is a kind of stainless steel suitable for nuclear power industry, which limits the amount of tantalum and drill.

 Why choose APT's Stainless steel tube heat exchanger?

The inner heat converter is made of seamless stainless steel, which has strong corrosion resistance, high heat transfer efficiency, non-magnetic, non-toxic and good heat resistance.

The outer barrel is made of stainless steeel , too.  solvent pressing and synthesis. It has good chemical stability and is not affected by environmental factors and medium composition in the pipeline. It has good corrosion resistance, low heat transfer efficiency, good insulation and heat preservation, and good energy saving effect. It is welded by professional process.

APT’s story

APT, Foshan Applied Process Technologies. We focus on two technologies application: thermal spraying and heat exchanger.

Our heat exchanger plant was set up in 2008, and soon encountered the well-known financial crisis, the economic environment suddenly deteriorated, and we immediately faced the problem of survival. Lowering quality and service standards has become the last trump card of many peers, but this goes against our original intention. We adhere to quality and service. For this reason, we have paid a price. A number of customers have lost, and some shareholders have withdrawn their capital, resulting in an unprecedented financial crisis. But we also got a surprise: after a few months, our lost customers came back with new products and cooperation. These customers are now our most loyal partners.

Over the past 10 years, whether it is to open up the market or to improve the satisfaction of the original customers, we rely on: Never say YES to poor quality and service.

APT's thermal spraying team began to study thermal spraying application technology in 2010. Fortunately, the company currently has a very professional thermal spraying technology team. Especially in aviation and paper machinery applications, we have been providing very professional products and services to domestic customers. Now, APT is the specialist applicator of thermal spraying, we produce a variety of thermal spraying coating, including HVOF, plasma, Arc, D-gun coating, we can provide coating detection and evaluation services, we can provide training services for coating research and development, we provide thermal spraying equipment design, thermal spraying production consumables. I believe that the company's strong technical background, will be able to meet customer demand for thermal spraying process.

Because of our reliable quality and 24-hour service support, we are particularly favored by exporters. According to incomplete statistics, 70% of our current business is exported overseas through traders. With the increase of business, quality management and service problems become more and more prominent. As we all know, TRADERS’ service to overseas customers is microphone-like. In many cases, it cannot solve customers' problems in a timely and professional manner. Overseas customers also cannot have the most favorable price and professional service provided by us as manufacturers. You know “focus on satisfying customers’ needs” is our company's way of survival. In order to enable global customers to have our more professional and direct products and services, we have carried out a series of restructuring and adjustment, which is now APT company.
