Indian Liquid Air Separation Unit being Installed in August

140TPD liquid Air Separation Unit designed and produced by Suzhou Xinglu Air Separation Plant Science and Technology Development Co., Ltd. for Indian customers has all arrived at the customer’s jobsite after three batches of transportation. This set of equipment is located in India, the whole set of equipment is now being installed.

After the equipment is produced by our company, in order to facilitate transportation, our company will deliver the cold box to the user site in two parts. After the customer picks up the goods at the port, most of the equipment has been put in place according to the packing list and installation instructions provided by our company.
As required by the customer, our technical service engineer arrived at the site on August 12, 2019 to guide the placement of the cold box. Our engineers have many years of rich working experience in guiding installation, and have also conducted installation work on several project sites.
The pictures show that after adjusting the verticality of the cold box, the lower section of the cold box should be in place first, and scaffolding should be built on the top of the cold box to prepare for the upper section of the cold box to be in place. In order to reduce aerial work and ensure the safety and stability of equipment, engineers of our company instruct site installers to install most of the ladder platforms before the upper section cold box is installed.





At present, the junction of the two sections of cold box is welding, the cold box is about 49.55 meters high.
Our technical service engineers successfully completed a week of site guidance installation work. The picture below shows the picture of the customer and the engineer at the site. The customer is very satisfied with the work of the technicians appointed to the site by our company. We are waiting for the customer to complete the remaining installation work on site as soon as possible.
Our company will successfully complete the debugging work as soon as possible, and the one-time start-up will be successful.

Early July of 2019, India project third shipment – whole set of equipment delivery from XLA

After the second shipment of goods were delivered in the middle of June, the third shipment of cold boxes left XLA`s factory in early July. XLA have many times meetings with this India project customer for the plant designed in the early stage, and after many discussions, negotiations and modifications,we two parties finally signed the purchasing contract in July 2018. After a year of intensive and orderly professional production and manufacturing, the delivery and loading of the third shipment of main cold box had successfully completed by the end of this month.
The cold box is tightly packed and covered with rainproof cloth in XLA factory. XLA has more than 30 years of production and design experience in the field of air separation, as well as rich experience in loading and delivery. The equipment loading process in the workshop is guided by the company’s professional masters, and the ropes are also specially fixed in order to avoid too much shaking and collision during transportation. XLA will look for large-scale shipping companies with professional experience in exporting air separation plant for storage and transportation, and require the personnel of the freight forwarding company to participate in the loading process in the company’s workshop so as to better understand the loading and lifting process.
The third shipment of equipment successfully arrived at Shanghai port in Mid-July. Below are the photos of unloading from the truck and loading provided by the forwarder.
FIG. 1 all the people work together to connect the lifting rope and equipment;
FIG. 2 slowly lift the equipment and move it onto the ship;
FIG. 3 fixed equipment after loading;
FIG. 4 shows the successful completion of equipment fixation.
During this period, under the guidance of the professional personnel trained by XLA, who will make joint efforts to ship the equipment safely.

The upper section and the lower section of the cold boxes were lifted and loaded onto the ship respectively by the site staff. These two sections of cold boxes were designed and produced by XLA and assembled on the jobsite. Due to the large equipment, the designers designed in two sections to facilitate transportation.

In the evening of the same day, all the third shipment of goods were loaded into the ship by lifting and other means with the full cooperation of the on-site personnel. It took seven hours to complete the loading and was already to ship to India. The next step is to wait for all the equipment to arrive at the customer’s jobsite in India, and after confirm with customer XLA will send professional engineers to guide the installation of the equipment.
Hope everything goes well! This plant is also about to be another successful case of plant in the Indian market.
