On March 10, 2023, HTKJ Valve Technology Corporation, a leading manufacturer of dual wedge gate and plunger valves in China, issued an announcement:
The world's largest 60 inch crack gas valve developed by the company has been manufactured. This product is the key equipment for the world's first 200,000 ton single furnace process ethylene cracking furnace, breaking international monopolies and achieving dual breakthroughs in technology and caliber.
During the product manufacturing process, the team innovatively adopted topology optimization to cast the valve body, improving its load resistance to 1.5 times that of the original valve without increasing weight, reducing the probability of product jamming; At the same time, upgrade the product structure to achieve product lightweight;
The use of labyrinth fairing reduces the amount of scouring by 90%, improving the product's service life; Using a one support two structure, the large valve drives the small valve, ensuring the safety of the cracking furnace.
With the same production capacity of 200,000 tons, a dual furnace cracking furnace requires two 48 inch cracking gas valves. It can be seen that the 60 inch cracking gas valve improves efficiency and saves costs.
The successful development of this product will strongly support the localization and internationalization of all equipment in the ethylene process package, and has taken a key step towards the subsequent application of innovation achievements and market promotion.
