On August 30, after a joint inspection by the general contractor Shanghai Huisheng Co., Ltd. and the design company China Ryukyu Engineering Co., Ltd., the 150,000-ton ethylene cracker of Dushanzi, which was constructed by China Petroleum Sixth Construction Company, reached the low-temperature oven condition and became the entire The only step of the chemical project is to complete the control target.
Liushan Petrochemical Company's eight 150,000-tonne cracking furnaces for Dushanzi Petrochemical is the leading unit of Dushanzi Petrochemical's one million tons ethylene project, and it is also the largest of its kind in China. The six-building company scientific organization, ahead of schedule, reasonable arrangements for processes, effectively speed up the progress of the project.
The cracking furnace construction technology belongs to the high-end technology of refinery chemical plants, and the installation accuracy and welding quality requirements are very high. The 45-meter-high furnace body frame verticality is controlled within 20 mm, and the primary welding qualification rate of furnace tubes must be above 98%. In this tough battle, the six-building company organized a group of experts to carry out technical research, successfully conquered the radiant section of the furnace tube, cracking gas pipe, oil transfer line, rising and falling pipe and other four construction difficulties, for the August 30 cracking The furnace paved the way to a low temperature oven condition.
Ren Lixin, deputy general manager of Dushanzi Petrochemical Company and deputy general commander of the project headquarters gave a high evaluation at the commenting meeting: During the entire construction process of the ethylene cracking furnace installation, no matter whether it is progress, safety, or quality, it is an exemplary example. Dare to "sword" for difficulties and reach the goal of the node.
At present, Liu Jian company has also scheduled a new plan, do a good job finishing the various work, lay the foundation for the November 10 China Communications.
Unlike many other bearings, Integral Shaft Bearings do not have an inner ring and instead work off of an inner race that is machined directly into the internal shaft. So what exactly makes up an integrated shaft bearing? Product specifications include:
• Chrome or stainless steel spindle shaft
• Thorough hardened chrome steel for outer race
• Chrome steel balls
• Steel or nylon cage designs available
• Steel shields closures as well as synthetic rubber, metal encased rubber, and metal encased labyrinth seals
• Soft shaft and engineered specials available
INTEGRAL SHAFT BEARING FEATURES
Due to their design, integral shaft bearings are very compact, allowing for either two rows of balls or a row of balls and a row of rollers. Our bearings are pre-packed with lubricant to ensure a long lifespan and are sealed to resist contamination.
