Our company has obtained the A2 and C2, C3 Pressure Vessel Fabrication Certifcates ,Grade GC1 Pressure Pipe& Vessel Construction Certifcates, ISO9001 Quality Certificate, ASME Certificate and U Stamp. So, if you ask for ASME stamp, we are able to manufacture your products under ASME standard.
Have you supplied tanks to any renowned companies?
Our group company is a regular strategic partner of some big gas companies, such as Messer, Boc, Air Product and Air Liquide, etc in China. We have supplied many storage tanks for them with different sizes. The biggest size we ever provided is 3000m3 ordinary pressure storage tank. We also made high pressure storage vessels for them, such as 100m3 LCO2 tanks, 10m3 (20m3, 30m3)LO2 (LN2, LAR) tanks. Meanwhile, we are one of the long-term storage tank suppliers for Pepsi and Coca-Cola in China.
As a giant cryogenic equipments company with more than 40 years history, we are a top two manufacturer producing air separation plants in China. The biggest air separation plant we have ever made is 60,000Nm3/h, famous for its advanced technology and reliable performance. Our air separation plant is also supplied to Messer Vietnam.
Can you provide the drawings of your plant/tanks?
Normally, our drawings will be provided to our customer only after the order is confirmed. However, we can provide you some drawings which belong to our old customers for reference. By the way, here, I need to remind you that our company only provides the engineering design drawings and the civil design drawings will be out of our range. Because every place has different situation, your side needs to find civil design company in your local market to do the drawings according to your specified environment.
How’s the producing time and delivery time?
Normally, our production time is 6 months for air separation plants but it also depends on the capacity you require. The bigger the plant, the longer time for production. Please also note that when the plant is finished, we need to wait for bulk vessel. It’s very common to wait for one or two months to find the right vessel.
The delivery date for tanks is 3-5 months.
