Pressure vessel design & pressure vessel drafting


Our scope of service:
We provide full range of services for design (mechanical) and drafting of various types of pressure vessels, storage tanks, process tanks and mixing tanks used in various industries such as oil & gas, food, beverage, brewery & general industries. Most of our clients are located around Klang Valley. Click here to download sample tanks and pressure vessels drawings.

Our strength: We believe we are the only engineers in Klang Valley that can provide proper stainless steel tanks design for food-related industries which includes mixing tank with agitators, jacketed tank with cavity plates etc. The design of food-grade stainless steel tanks requires the knowledge of various food processing practice and components, such as gear-motor agitator, mechanical seal, product mixing, air ventilation, jacketed tank heat transfer, surface finishing, cleaning with CIP and other sanitary consideration for fabricating stainless steel tanks. We can also calculate theoretical tank partial volume for both vertical and horizontal tanks with flat or dished end, thus eliminates manual volumetric tank calibration.

Our code knowledge:  Pressure vessels construction code such as ASME VIII DIV I, TEMA, PD5500, API 650, API 620, AS1210, MS830, UL 58, UL 147 etc as well as local authority DOSH requirements.
