According to the latest data released by the National Bureau of Statistics, in January 2016, the national producer price of industrial producers (PPI) fell by 0.5% month-on-month, a decrease of 5.3% year-on-year.
Yu Qiumei, senior statistician of the Urban Statistics Department of the National Bureau of Statistics, reads:
In January, the ex-factory prices of industrial producers fell by 0.5% month-on-month, and the decline slowed by 0.1% from the previous month. The slight decrease in the chain ratio was due to the fact that the ex-factory prices in some industrial sectors decreased or decreased. Among them, the ferrous metal smelting and rolling processing, non-ferrous metal mining prices from the previous month's decline to this month's rise of 0.1%, 0.6%; non-ferrous metal smelting and rolling processing prices from the previous month's decline to the month The prices of chemical raw materials and chemical products fell by 0.7% month-on-month, 0.2 percentage points lower than the previous month's drop.
In January, the ex-factory prices of industrial producers fell by 5.3% year-on-year, a decrease of 0.6% from the previous month. The year-on-year decline was mainly due to the lower base of comparison in the same period of last year (down 1.1% in January last year). In terms of different industries, the ex-factory prices of ferrous metal smelting and rolling processing, petroleum processing, non-ferrous metal smelting and rolling processing, and chemical raw materials and chemical products are still down by more than the same period last year, falling by 19.0%, 13.5%, 12.1%, and 6.3%, respectively. The total level of ex-factory prices of industrial producers in the month fell by 2.8 percentage points year-on-year, accounting for about 53% of the total decline.
Overview
UN type Seals are one-way acting Sealing elements, in hydraulic cylinders, mainly used for piston rod sealing, in many applications, especially in mobile machinery, automobiles, forestry and mining machinery, under harsh working conditions , has good mechanical properties. In heavy-duty occasions, it has a very good effect when used in conjunction with the RS-type step Seal.
advantage
In addition to the advantages mentioned above, as well as the advantages of good sealing effect and easy installation, the Sealing Element also has the advantage of low friction in the low pressure range.
Scope of application
It is suitable for piston rod sealing and has a wide range of applications, especially in hydraulic equipment such as mobile machinery, automobiles, forestry and mining machinery.
