According to the agricultural situation of the Ministry of Agriculture, as of October 8, the national autumn grain harvest has been completed 51.2%, and the progress is 5.3 percentage points faster than the same period last year. In terms of crops, the medium rice (one rice) has received 50.9%, which is 2.3 percentage points faster than the same period last year. Corn has received 57.9%, up 9.6 percentage points year-on-year. Soybeans have received 54.5%, up 0.6 percentage points year-on-year. In terms of regions, the autumn harvest in the southwest region was over 70%, the Huanghuaihai area and the northwest region were over 60%, and the northeast region was over 30%. The progress was faster than the same period last year. Nearly 40% of the middle and lower reaches of the Yangtze River and South China were slightly slower than the same period last year.
A reducing elbow is a type of fitting which is used to join two pieces of pipe of different sizes. The reducing elbow is so called because it looks like a reducing piece and elbow combined into one.
When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.
Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. It required more space than short radius elbow.
An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.
Types of reducing elbow:
The reducing elbows are available in various types like:
90° reducing elbow
45° reducing elbow
135° reducing elbow
180° reducing elbow etc
In long radius elbow, centreline radius is 1.5 times the nominal size of the pipe or you can say 1.5 times the diameter of the pipe.
Buttweld pipe fittings comprises of long radius elbow, concentric reducer, eccentric reducers and Tees.They are an important part of industrial piping system to change direction, branch off or to mechanically join equipment to the system. Buttweld fittings are sold in nominal pipe sizes with specified pipe schedule. BW fitting`s dimensions and tolerances are defined as per ASME standard B16.9.
Butt Weld fittings are also called Welded Pipe fittings. These welded fittings in carbon steel and stainless steel offer many advantages compared to threaded and socketweld fittings. The later are only available up to 4-inch nominal size whereas butt weld fittings are available in sizes from ½" to 102".
Reducing Elbow: Fittings that change direction in a piping system are called elbows. The directional change is given in degree such as 45 or 90. Long radius 90 degree elbow has the center line of elbow at 1.5 x NPS from eblow end. And the elbow ends in two different outdiameters
[China Agricultural Machinery Industry News] It was learned from the Ministry of Agriculture that in recent days, most of the country's weather is conducive to autumn harvesting, and all localities have earnestly implemented the spirit of the national autumn and winter work video conference, intensified efforts, and strengthened measures to promote the smooth development of autumn harvest autumn seeds. At present, the national autumn harvest is more than half, and the wheat has been broadcasted by 10%, and the progress is faster than the same period last year.
2016 autumn agricultural machinery operation progress: autumn harvest over half of the wheat broadcast over 10%
Since October 4, there has been a significant rainfall process in the winter wheat area. The rainfall in southeastern Gansu, north-central Shaanxi, north-central Shanxi, north-central Hebei, Beijing, etc. reaches 10-25 mm, including Beijing, Hebei Zhangjiakou and Baoding, Shaanxi. The rainfall in Yulin Bureau is 50-80 mm. The rain process has effectively improved the soil moisture and facilitated the sowing and emergence of winter wheat. As of October 8, the country's winter wheat has been planted 10%, and the progress is faster than the same period last year. Among them, nearly 50% have been completed in the northwestern region, and the five provinces of Gansu, Henan, and Jiangsu have passed the same rate, and the planting in the southwest has just begun. Nearly 20% of the winter rapeseed has been planted throughout the country, and the progress is comparable.
According to the Central Meteorological Observatory, in October, most of the precipitation in the winter wheat area and winter rapeseed production area is equal to or more than normal, which is conducive to the smooth development of autumn seeds. The Ministry of Agriculture will pay close attention to the weather changes, timely dispatch rain, lyrics and autumn harvest autumn schedules, guide locals to grasp the fine weather, give full play to the role of agricultural machinery, speed up the autumn harvest, plough the land, planting, and timely rumors in areas with poor grievances. Sowing, improving the quality of sowing, ensuring timely sowing and sowing.
