Many world-famous valve makers closed their factories in North America, Europe, and Japan to China, India, South Korea, and Central Europe to reduce the cost of valve production and increase sales profits. Following the increase in the development and use of oil and natural gas in China, China's valve shopping malls have increased significantly, which makes most valve manufacturers pay more attention to building factories in China. Therefore, there is an upsurge in the establishment of foreign valve companies in China. Some companies even have multiple factories in China to shorten the delivery distance and delivery time.
Except for some special valves, domestically produced valves can basically meet the needs of the national economy in various fields and infrastructure construction. In particular, in recent years, major breakthroughs have been made in the localization of millions of kilowatts of nuclear power station valves, represented by China Nuclear Su Valve Technology Industrial Co., Ltd., Dalian Dagao Valve Co., Ltd., Jiangsu Shentong Valve Co., Ltd. and Shanghai Valve Factory Co., Ltd. A number of key enterprises have developed important nuclear-level valve products, among which the nuclear-level shut-off valves, check valves, ball valves, butterfly valves and most of the gate valves have been domestically produced. The localization rate of nuclear power valves has increased from 6% 8 years ago to more than 75%. The valve companies represented by Chengdu Chengfeng Valve Group, Wuzhou Valve Group and Shanghai Nile Rice Co., Ltd. developed fully welded pipeline ball valves (PN5-15MPa, DN28′′-48′′) for long-distance natural gas transmission pipelines, and welded below 48′′ Pipeline ball valves can be fully domesticated, and the development of these new products has filled the domestic gap, and some products have reached or are close to the world's leading level.
No matter how the valve industry develops, the quality of products is the foundation of our development, and the core technology of science is the catalyst for our development. We believe that we must adhere to our own principles and find our own way before we can continue to make breakthroughs in our development.
Water well drilling rig is a efficient,multi-function full hydraulic water well drilling rig.It is high efficiency because of having a larger torque of the turntable and is mainly used for water well in industry and agriculture, national defense building foundation, geological exploration, geothermic well and other foundation working, it is popular at home and abroad.
Crawler mounted drilling rig can drilling in all kinds formations by mud drilling in soft formation and air DTH hammer in rock drilling,DTH Hammer is applied in rock drilling, slag is discharged by air pressure and the offstage efficiency is ten times than traditional rotary drilling.
Deep water well drilling rigs, in cutting drilling or rotary drilling can be operated in unconsolidated layer, and the slag can be discharged under by mud, the impact drilling operation can also be adopted and slag can be discharged by pressure air, the hydraulic water well drilling rig suitable for drilling complicated geological conditions.
