The equipment engineer of DDTS can join in the engineering design team of client.We can assist client to design and drawing vessel, heat exchanger, tower and other static equipment by using Auto CAD and other drawing software, as well as SW6, Compress, PV Elite and other equipment design software. Meanwhile, DDTS can also assist client to make inquiry drawings, mechanical design data sheet and other procurement documents.

Conventional Equipment-Jacketed Stirring Container Design Case 2015-Nanjing-PV EliteStirring Container Design Project: The lower end of the cylinder body was jacketed. Equipment inside diameter is 5300mm; total height is about 13.5m; the medium could cause death; the volume is 195 cubic meters; principal materials are C.S.+10276 composite plate. The design criteria are ASME VIII-1; Calculation software is PV Elite.

Conventional Equipment-Special Material Heat Exchanger Design Case 2015-Shanghai-PV Elite

Conventional Equipment-Special Material Heat Exchanger Design Project: the area of heat exchange tube is 610m2; principal materials of tube pass are C.S.+10276 composite plate; tube sheet materials are composed by three different layer of C.S.+Ti+Zr. The design criteria are ASME VIII-1; Calculation software is PV Elite.

Conventional Equipment- Double Tube Plate Heat Exchanger Design Case 2016-Shanghai-SW6。

Since the medium of this equipment tube pass is highly toxic, a double tube plate structure is applied here. We check the calculation of the structure by using the latest software of SW6.

Conventional Equipment-Tower Design Case 2015-Shanghai-PV Elite

Tower Design Project: the total height of the tower is 46 meters; assembly weight is 130t; the design criteria are ASME VIII-1; Calculation software is PV Elite.

Pressure Vessel-Tower Construction Reinforcement Structure Strength and Liability Analysis Case 2014-Nanjing-Ansys

Pressure Vessel Repair Project: due to the serious corrosion of the middle section this equipment the cylinder was needed to be replaced. A reinforcement structure would be temporally constructed during the replacement. We help our clients to check and analysis the strength and liability of the reinforcement structure using finite element analysis method.

Conventional Equipment-Water Treatment Equipment Case 2016-Shanghai-SW6 & PV Elite

DDTS provide technical support and equipment design service for water treatment industry, design glass steel tank, plastic tank, pressure vessel, ladder platform, steel structure platform, pressure container, and other equipment according to the criteria of HG/T 20696-1999, JB/T 2932-1999, GB 150-2011, ASME.VIII.Div.1. or other standards, and provide technical support for equipment from suppliers such as filters.

Scaling Heat Exchanger Technological Transformation Case 2012-Nanjing-Aspen EDR

The heat exchanger fouling serious before reformation, an average of 1 to 2 months to parking overhaul, it’s seriously affect the normal production operation. Through analyzing the reason of the heat exchanger fouling, DDTS proposed the reformation solution and the structure of the heat exchanger was reformed, after the reformation the fouling is reduced obviously. The figure shows the structure of before and after the reformation.


Equipment Leakage Failure Technology Reform Case 2012-Nanjing-Aspen EDR

A leakage caused by the heat exchanger tube vibration, corrosion under the scale which finally caused the equipment leakage failure. Tube with baffle joints the tube was abraded and the external surface of the tube had a large area of ulcer corrosion pits. We proposed the solution through analysing the failure: to eliminate the vibration completely solved the problem of tube leakage, reformed tube bundle, at the same time to prevent the harmful ion concentration in process water, added an outlet to strengthen sewage discharge capacity in shell side. The figure shows the structure of before and after the reformation.
