The world's largest PTA oxidation reactor off the assembly line

Drying equipment

Recently, Nanjing Baose Co., Ltd. manufactured the 1.2 million tpa PTA oxidation reactor with the largest global specifications, the highest single unit capacity, and the most difficult manufacturing process. The line was delivered to users via the large port of Binjiang Port area.

According to Wang Jianping, general manager of Nanjing Baose Co., Ltd., PTA, as an important basic chemical raw material, is mainly used in polyester fibers, films, coatings, engineering plastics and other industrial fields, and is increasingly used at home and abroad. However, due to weak domestic independent development capabilities, China's production of PTA technology and equipment has been dependent on imports, only a patent fee, every one ton of product to be produced to pay $ 30, the cost is extremely high.

On February 7, last year, Nanjing Baose Co., Ltd. produced a domestic first million-tonnage PTA oxidation reactor with a diameter of 6.8 meters and a total weight of 305 tons, which made a major breakthrough in the key technologies for the production of PTA production core equipment. The domestic gap broke the foreign monopoly of China’s manufacturing of key PTA equipment.

The 1.2 million-ton/year PTA oxidation reactor manufactured by Nanjing Baose Co., Ltd. has a diameter of 7.8 meters, a length of 40 meters, a total weight of 420 tons and a volume of 1200 cubic meters. It is manufactured entirely using domestic and domestic technologies. During the manufacturing process, the company successfully tackled more than a dozen technical difficulties, and refreshed its own manufacturing record for the localization of the large million-ton-ton PTA oxidation reactor.

NPT, PT, G is the pipe thread.
NPT is National (American) Pipe Thread abbreviation belong American standard tapered pipe thread 60 degree, for North America. National standards can be found GB / T12716-1991
Pipe Thread PT is an abbreviation, is 55 degrees sealing cone pipe thread, is a Whitworth thread family, more for Europe and the Commonwealth countries. Commonly used in water and gas pipe industry, defined as 1:16 taper. National standards can be found GB / T7306-2000
G is 55 degrees non-thread sealing pipe thread, is a Whitworth thread family. G represents a threaded barrel mark. National standards can be found GB / T7307-2001
Also thread 1 / 4,1 / 2,1 / 8 mark refers to the thread diameter in inches.
Insiders usually points to refer to the thread size, one inch equals 8 points, 1/4-inch is 2 points, and so on.
G is the pipe thread collectively (Guan), divided into 55, 60 degrees are functional, commonly known as a round tube. That thread processing is made by a cylindrical surface.
ZG commonly known as the funnel, that thread processing by a conical surface made of pipe joints in general are like this, the old domestic thread standard male thread Rc labeled as R
