    product description

    Hydraulic pressure is a device that transmits pressure through hydraulic oil (specifically determined according to the actual situation). Hydraulic equipment often uses oily medium, so the rubber joints supporting it must have good oil resistance. If general rubber materials are used, when the oil and rubber are in contact for a long time, the rubber molecules will swell, which will cause local expansion of the product, which will seriously affect the pressure-bearing performance of rubber joints. The special rubber joint, Xinli nitrile rubber joint, also known as hydraulic equipment rubber joint, is a high elasticity, high air tightness, medium resistance and weather resistance of pipe joints. This product has good oil resistance and has good adaptability to the current stage of hydraulic oil pipelines.

    Product advantages

    Special rubber joints for hydraulic equipment have excellent ability to adapt to the operating environment of hydraulic equipment. Not only that, this product, like other general-purpose rubber joints, can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes. Widely used in various pipeline systems. This product is manufactured by Luoying Company using a new process of air-blowing mold. It is a product composed of a ball composed of inner rubber layer, reinforcement layer, middle rubber layer and outer rubber layer, and loose-forged low-carbon steel flange. , Good elasticity, large displacement, good vibration and noise reduction, easy installation and so on.

    Performance characteristics

    1. The product has high internal density, can withstand high pressure, and has good elastic deformation effect.
    2.Special rubber joints for hydraulic equipment for shock absorption, noise reduction, lightweight, non-toxic.
    3. The connection of special rubber joints for hydraulic equipment with pumps and valves, especially suitable for pipelines with large vibration and frequent changes in hot and cold. Special rubber joints for hydraulic equipment are composed of fabric-reinforced rubber parts and loose metal flange connections, which are used for pipe vibration isolation and noise reduction and compensation for displacement.

    Classic Case

    Xinli Pipeline supplies rubber joints to Baosteel Zhanjiang Iron and Steel Project

    Baosteel Zhanjiang Iron and Steel No. 2 blast furnace successfully ignited on the 15th and put into trial operation. At this point, the first phase of Baosteel Zhanjiang Iron and Steel Co., Ltd. has been widely built, with an annual output of more than 8 million tons.

    It is understood that after the blast furnace of Zhanjiang Iron and Steel No. 1 of Baosteel was ignited on September 25 last year, the Zhanjiang Iron and Steel Base of Baosteel officially entered the trial production phase. In less than one year, nine major low-carbon soft steels and ordinary structural steels were quickly completed Expansion of similar steel types.

    Baosteel Zhanjiang Iron and Steel Base said that after the No. 2 blast furnace was put into operation, the No. 1 and No. 2 blast furnaces were running at the same time, the production scale was expanded, the production capacity would be rapidly increased, and the economic benefits would be more prominent. In particular, the manufacturing industry in Southeast Asia is currently on the rise, and the steel market is in great demand. Zhanjiang, as a strategic fulcrum city for China ’s Belt and Road maritime cooperation, is a city with a short voyage from Southeast Asia to China. Prospects for the development of foreign trade economy.

    The Baosteel Zhanjiang Iron and Steel project is led by Baosteel Group. It started at the end of May 2012 with a total investment of 69.6 billion yuan. The construction scale is to produce 9.2 million tons of iron, 10 million tons of steel and 9.38 million tons of steel annually.

    Xinli Pipeline, as the main supplier of rubber joints for this steel project, will ensure the supply of products, especially the supply of special rubber joints for hydraulic equipment. We will enter the factory for inspection, production and processing of raw materials for each rubber joint. Every link such as factory quality inspection is carefully tested and inspected to ensure that the quality of the product can meet the user's expectations.
