4. Enterprise's strength:
- Dong Anh Pressure equipment J.S Company import direcly 100% main materials, we donot buy from trading company in order to Warrant material quality and Suppliers' experiences. We make sure our material all meet requirement for fabricating boilers & decrease the price.
- Main material such as: steel plate, seamless steel pipe are direct import with Unique dimension (width 2m, steel pipe 11m length) in order to create nicer products.
- Thiết kế đột phá, không đi theo lối mòn giúp đường hơi đi dài hơn, nhiêu liệu đốt đa dạng hơn (vỏ dừa khô, gỗ thừa…), mang lại hiệu quả kinh tế cao cho sản phẩm khi đưa vào thực tế;

- Thiết kế đột phá, không đi theo lối mòn giúp đường hơi đi dài hơn, nhiêu liệu đốt đa dạng hơn (vỏ dừa khô, gỗ thừa…), mang lại hiệu quả kinh tế cao cho sản phẩm khi đưa vào thực tế;
- Professional techinicians, high level weld man (5G, 6G - TCVN) help products always satisfy technique and nice.
- Modern workshop, modern machines such as CNC plasma cutting machines, CNC bending machines, Steel cutting machines, Flanging machine, Pressing machine, Auto welding machine, craine... help us to decrease manual factors, increase productivity and accuracy.
5. Products' strength:
The boiler and Tanks are designed & fabricated by Dong Anh Pressure equipment JSC have their own statement in Vietnam market and Clients' heart.
The strengths of our products: Pressure tank
- All of air storage tanks, pressure tanks, LPG tanks and oil tanks have 39 months warranty. They all pass the technical and safe standards in Viet Nam, such as the pressure tanks: TCVN 6153 to 6156÷1996 ; TCVN 7704÷2007;TCVN 8366÷2010.
- Otherwise, they also satisfy the international standards such as GB, JIS and other standards.
- Especially, the two elliptical heads of a pressure tank are made of steel Q235B, Q345(A516 – Gr70), 20G, A515 –Gr60 according the GB pressure standard which ensures the high quality and durability. Otherwise, we apply the modern technologies and the product is welded by an automatic machine. The bracket could whirl automatically and is welded from inside and outside.
- Achieve a gold medal for excellence products and services in 2013
The strengths of our products: Boilers
- Boilers have 3 passes with bigger steam drums, longer steam tubes in order to take the heat throughly, farther distance between the tubes to avoid deposits which help the easier cleaning work (because the supplied water in Vietnam is not well-treated). In addition, boilers are insulated by 2 layers (heat-resistant bricks + insulation glass wool, heat resistant concretes) in order to get higher temperature in furnace, and to burn fuel completely. Fuel is absorbed utterly to help saving coals, eliminating redundant dust. Boilers are installed firmly, boilers equipments which are imported with high quality in order to decrease cost and operate easily.
- The cleaning door of the steam drums are bigger based on the new technical method which is easier for the cleaning work.
- Coal supplied doors are bigger which is easier for supplying and taking the slag.
- Tudom doors are bigger which is easier for the cleaning work.
- By using the modern technology, this boiler has fewer hot wind blocks, longer hot-wind paths with less dust deposited. Otherwise, cleaning doors are designed for one average worker comes in easily to check, repair or maintenance.
- The economizer is installed behind the boiler to take the heat of exhausted smoke in order to increase the boiler efficiency, lower the cost, and decrease the smoke temperature before going out of the chimneys.
- The economizer is installed behind the boiler to take the heat of exhausted smoke in order to increase the boiler efficiency, lower the cost, and decrease the smoke temperature before going out of the chimneys.
- Wet dust treatment is designed according to the new technical methods from German and China, which can decrease 80% ¸ 90% of exhausted dust, which help clean the boiler, the site and preserve the surrounding environment.
- In 2008, we were rewarded by the Vietnam Business Association for the products “Boilers, pressure tanks and pressure equipments”
- Achieve a gold medal for excellence products and services in 2013
