Since the second quarter of last year, with the recovery of global trade, international shipping prices continue to climb, constantly refresh the “record.” In the first half of 2021, shipping prices continued to “rise”, and professional agencies predict that the trend will continue in the third quarter.
China’s shipping industry is in the best recovery period in history, and the country’s shipping market is expected to continue to pick up in the third quarter of 2021, according to a new report released by the Shanghai International Shipping Research Center on July 5. At the same time of capacity increase, freight rates will also usher in a new round of rising prices.
According to Zhou Dequan, director of Shipping Development Research Institute of Shanghai International Shipping Research Center, in the third quarter of 2021, the climate index and confidence index of shipping related enterprises will still remain above the scenery line. Among them, China’s shipping climate index is expected to be 121.00 points, down 5.40 points compared with the second quarter, maintaining in the relatively prosperous range. China’s shipping confidence index is expected to be 162.73 points, down 1.46 points compared with the second quarter, still maintaining in a strong climate range. Chinese shipping industry thaw trend is visible from this spot.
In the second quarter of 2021, China’s shipping climate index reached 126.39 points, a new record high since the release of the index. China’s shipping confidence index was 164.20 points, basically flat with the first quarter, maintaining in a strong climate range.
Shipping enterprises continue to increase the delivery of shipping capacity
In the second quarter of 2021, the shipping capacity of shipping enterprises continued to increase, the utilization rate of shipping space continued to rise, and the freight income increased significantly. In spite of the significant increase in operating costs, the company still maintains a strong profit; Loan liabilities continue to reduce, labor demand increased substantially, working capital is very comfortable, enterprise financing is relatively easy, shipowners’ willingness to invest in transport capacity continues to strengthen, enterprise risk resistance ability rises steadily.
The report shows that in the second quarter, the climate index of shipping enterprises is 132.70 points, 12.85 points higher than that of the first quarter, entering a relatively climate range. The confidence index of shipping enterprises was 168.66 points, down 4.96 points compared with the first quarter, but still maintained in the strong climate range, indicating that entrepreneurs have sufficient confidence and are optimistic about the future prospects.
Container transport companies in the second quarter made a big profit, entrepreneurs are full of confidence in the future business, optimistic about the market. In the third quarter, the climate index of container transport enterprises is expected to be 136.09 points, and the confidence index is expected to be 168.31 points, both entering the relatively climate range.
After making profits from the second half of 2020 to date, shipping companies said in the third quarter that they will continue to increase the launch of ship capacity. According to the survey conducted by China Shipping Climate Index Compilation Office of Shanghai International Shipping Research Center on the planned new shipping capacity of shipping enterprises in the next quarter, 18.63% of the enterprises said that they expected the new shipping capacity to increase by more than 20% compared with the second quarter. 25.49% of the enterprises said they expected the new capacity to increase by 10%~20% compared with the second quarter; 36.27% of the enterprises said they expected the new capacity to be basically the same as the second quarter; 17.65% of the enterprises said they expected the new capacity to drop by 10% to 20% compared with the second quarter. 1.96 percent of enterprises said they expected new capacity to drop by more than 20 percent from the second quarter.
Pneumatic fittings are required in any kind of pressurised gas system to link together sections of tubing, pipe or hose. They typically have tighter seals and are subject to lower pressure than hydraulic fittings, and are frequently found in pneumatic instrumentation and logic control systems, as well as moving parts such as cylinders.
Although fittings may represent the minutiae of the overall pneumatic system design, they are perhaps the most important of all the elements. Pneumatic fittings, together with their pipes, hoses and tubes, connect all the other major components together, and can therefore have a major influence on the efficiency, safety and energy consumption of the entire system.
Pneumatics are used in many of today’s industrial and automation environments, and there is an increasingly wide range of options from which to choose your components. Knowing how to choose pneumatic fittings is therefore all about suiting the materials to the job and its environment. In order to break down this process, you first need to identify:
the specific environment in which your equipment will be working
the required air pressure or PSI specification of your equipment
any approvals that may be needed for the equipment and its components
the material(s) from which your fittings should be made
the type and size of tubing you will require
the type and size of thread your fittings will need
Dear friends and customers :
we come back to work from holiday. We thank everyone for your support and trust in the past years. I hope that in the new year, BLCH will continue to receive everyone's attention and support, and we , as always , provide better service to everyone !
GOOD-LUCK OF BEGINNING !
Solenoid valve selection should first follow the four principles of safety, reliability, applicability, economy, followed by six aspects of the field conditions (namely, pipeline parameters, fluid parameters, pressure parameters, electrical parameters, mode of action, special requirements to choose).
Selection basis:
First, according to the pipeline parameters to select solenoid valve: diameter specification (i.e.), interface mode according to the field pipe diameter size or flow requirements to determine the size of diameter 0.Interface mode, general > to choose flange interface,< can be freely selected according to user needs.
Second, according to the fluid parameters of the solenoid valve: material, temperature groupCorrosive fluid: should choose corrosion resistant solenoid valve and all stainless steel; Edible ultra-clean fluid: food grade stainless steel solenoid valve should be selected.High temperature fluid: the solenoid valve made of high temperature resistant electrical materials and sealing materials should be selected, and the type of piston structure should be selected.Liquid state: large to gaseous, liquid or mixed state, especially when the diameter is larger than the order must be distinguished., fluid viscosity: usually in the following can be arbitrarily selected, if more than this value, to choose high viscosity solenoid valve.
Third, according to the pressure parameters to choose the solenoid valve: principle and structure varietiesNominal pressure: this parameter and other general valve meaning is the same, is based on the nominal pressure of the pipelineWorking pressure: if the working pressure is low, it must choose direct motion or step by step direct motion principle; When the minimum working pressure difference is above, direct acting type, step by step direct acting type and pilot type can be selected.
Fourth, electrical selection: voltage specifications should be preferred as far as possible, more convenient.
Fifth, according to the length of continuous working time to choose: normally closed, normally open, or sustainable electricityWhen the solenoid valve needs to open for a long time, and the continuous time is more than the closing time should be used normally open.If the open time is short or open and close time is not much, then choose normally closed type.However, some working conditions for safety protection, such as furnace and kiln flame monitoring, can not choose normally open, should choose long-term electrified type
Sixth, according to the environmental requirements to select auxiliary functions: explosion-proof, check, manual, waterproof fog, water spray, diving explosive environment: the corresponding explosion-proof solenoid valve must be selectedWhen there is a backflow of fluid in the tube, the solenoid valve with check function can be selected.When you need to manually operate the solenoid valve on site, you can choose the solenoid valve with manual function.Open air installation or dust more occasions should choose waterproof, dustproof varieties (protection grade above).
