The double flow tubular compensator, also known as tubular expansion joint, is the compensation device of thermal fluid pipeline, which is mainly used for the auxiliary equipment of linear pipeline. The service life of double flow sleeve type compensator is long and its fatigue life is equivalent to that of pipeline. The service life of the dual flow compensator is equivalent to that of the pipe. After special treatment, the sliding surface has good corrosion resistance in salt water and salt solution, which is more than 50 times higher than that of austenitic stainless steel. At the same time, when the sealing effect is weakened due to wear and tear after many years, the flange can be tightened again to enhance the sealing performance. The bolt can also be loosened, the pressure ring can be removed, and then one or two layers of sealing ring are installed to compress the pressure ring, which can be used continuously.

Product advantages

After special treatment, the sliding surface of the product has good corrosion resistance in salt water and salt solution, which is 50 times higher than that of austenitic stainless steel. At the same time, when the sealing effect is weakened due to wear and tear after many years, the flange can be tightened again to enhance the sealing performance. The bolts can also be loosened, the pressure ring can be removed, and then one or two layers of sealing ring are installed to compress the pressure ring and continue to use. It is easy to install and repair the eccentric sleeve, which can prevent the installation of the equipment from damage. The double flow sleeve type compensator has the characteristics of positive and negative two-way steam supply. It is not necessary to consider the flow direction of the medium during installation; in addition to the characteristics of the original directly buried type, such as large compensation amount and quick and convenient installation, the compensator is more safe and reliable in the use process due to the use of the diversion tube with special structure. The compensator is mainly used for direct burial, trench or overhead, etc. The double flow sleeve type compensator has reasonable structure, good elasticity, wide range of thermal expansion and cold contraction of compensation pipeline, small reaction force to pipe support, vibration absorption and noise reduction, heat insulation and dust isolation, which is beneficial to simplify the support structure. The double flow tubular compensator, also known as tubular expansion joint, is the compensation device of thermal fluid pipeline, which is mainly used for the auxiliary equipment of linear pipeline. It is suitable for hot water, steam, grease and other media. The sliding movement of the outer sleeve through the sliding sleeve can compensate the thermal expansion.

Shanghai Luoying cooperates with Guinea hydropower station with a total installed capacity of 450000 kw


The reporter learned from China Three Gorges Corporation on the 25th that the Three Gorges group has successfully signed a contract for the suapiti hydropower station project in Guinea with a total installed capacity of 450000 kW.
According to the introduction of the Three Gorges group, suapiti hydropower station is the second stage hydropower station in the cascade development of the konkule River in Guinea, 135 km away from the capital of Guinea, conakro. The normal water level of the power station is 210 meters, and the total installed capacity is 450000 kilowatts. After completion, it can not only meet the domestic power demand of Guinea, but also transmit the surplus electric energy to Gambia, Senegal and other surrounding areas.
Features of double flow sleeve type compensator produced by Shanghai Luoying: Based on summarizing the advantages of similar products at home and abroad, the sleeve type compensator manufactured by our company is developed and produced by adopting advanced sealing structure and sealing materials, with reasonable structure, safety and reliability, long service life, no leakage, convenient installation and maintenance, and wide application range.
On January 20, the Three Gorges group and relevant departments in Guinea officially signed the general contract for suapiti hydropower project, with a contract amount of 1.38 billion US dollars and a contract period of 58 months. This is also the second large-scale hydropower project signed by Three Gorges group in Guinea after kaileta hydropower station.
