According to statistics, from January to June this year, China's bearing industry realized a total profit of 1.45 billion yuan, a decrease of 41.87% from the same period of last year, and bearing stocks also increased from 4.70 billion yuan in the same period last year to 5.23 billion yuan, an increase of 11.30%.
The monthly production report of the major manufacturing enterprises in the bearing industry shows that in the first half of this year, 104 enterprises participating in the statistics of the bearing industry in China produced a total of 2.11 billion bearings, a year-on-year increase of 4.76%; sales volume was 1.95 billion sets, a year-on-year decrease of 2.89%.
Although output has increased, output value has declined. In the first half of the year, the total industrial output value was 28.31 billion yuan, a year-on-year decrease of 6.97%, and the industrial sales value was 28.17 billion yuan, a year-on-year decrease of 6.60%.
In terms of imports and exports, from January to June this year, China's total exports of bearings were 2.239 billion sets, a decrease of 2.4% from the same period of last year, and foreign exchange earned 2.205 billion U.S. dollars, an increase of 7.6% over the same period of last year. Accumulatively, 957 million sets of imported bearings were used, with a total of 1.731 billion U.S. dollars, which was a decrease of 5.8% and 16.82% respectively from the same period of last year. Compared with the previous month, the surplus of import and export trade continued to increase, with a surplus of 474 million U.S. dollars.
From the perspective of export product composition, cylindrical roller bearings still maintained a significant year-on-year growth, but with the increase of 150.33% last month, the growth rate continued to decline, with a year-on-year increase of 141.7%; self-aligning bearings only increased by 6.7%. The rate of other bearings also fell in different magnitudes.
The amount of foreign exchange has slightly changed compared with the previous month. Thrust ball bearings have changed year-on-year in the previous months, and the amount of foreign exchange earned in June increased by 11.1% year-on-year. In addition to a slight decrease in spherical roller bearings, the others have shown an increase over the same period of last year.
The relevant experts of the association pointed out that the bearing outlet structure changes require attention. However, from the point of view of the entire export product, the growth rate of export volume and foreign exchange earnings has continued to decline compared with the previous month.
From the point of view of the composition of imported bearings, the year-on-year ratio of deep groove ball bearings has changed slightly with a slight increase. Other products are basically the same as last month, and only angular contact ball bearings, thrust ball bearings, cylindrical roller bearings and tapered roller bearings Import volume increased slightly. With respect to foreign exchange, apart from the fact that the number of thrust ball bearings is increasing both in terms of volume and use of foreign exchange, the import volume of tapered roller bearings, angular contact bearings and cylindrical roller bearings has increased despite the increase in the use of foreign exchange. As a whole, the volume of imports and the use of foreign exchange have both declined.

Casting elbow appearance
As the appearance of the welding elbow, then we say that the appearance of the casting elbow bar. Casting elbow appearance are fixed, of course, the general casting elbow appearance is according to different steel tube and to choose the different knowledge of casting elbow, so, in order to ensure the casting elbow appearance, usually Steel Pipe in the future, if not been yard rain washing off, then welding elbow after high temperature push general weld appearance of the elbow is appear out of the blue, of course, if the rain washed, we in high temperature after heating, heating welding elbow surface color are red. But overall, we guarantee tube is washed by the rain is very difficult, because is yard in summer is rain fog water washed, then push the system out of the welded elbow surface is red, too.

Geometric dimensions include outside diameter, inside diameter and wall thickness. Also requires control

Radius of curvature. For example, the radius length is 1.5D, and the radius of curvature must be within the range of tolerances required. Due to these fittings, most used for casting, in order to improve the welding quality, end vehicles into the groove, leave a certain angle, side band, this requirement is quite strict, edge thick, at an angle of number and range of deviation provisions, geometric size than pipe much many. The surface quality and mechanical properties are basically the same as that of the tube. In order to facilitate welding steel, and the connecting pipe are the same. Fourth, is all the pipe fittings should be through the surface treatment, the inner and outer surface of the oxide scale through shot blasting, and then coated with anticorrosive paint. This is not only for export needs, in addition, in the country is to facilitate the transport to prevent rust oxidation, to do this work. Fifth is the packaging requirements, for small pipes, such as export, you need to do wooden, about 1 cubic meter, this provision in the case the number of elbows about not more than a ton, the standard allows the suit, large sets of small, but the total weight usually do not more than 1 ton. For large to a single package, like 24 "must be a single package. The other is labeled packaging, labeling is to indicate size, number, batch number, manufacturer trademark. In the pipe to be stamped on stamp, and attached to the packing list and the quality book file.
