Steel bend
Compared with elbows, bend will have tangent length if the customers need. The bend radius is larger than elbows`. When it is more than 2D, it is called bend. There are 3D, 5D, 7D, 10D bends. Below picture is 3D bend with tangent length, angle is 45deg and 90deg.
Carbon steel 3D bend
These bends are packed by wooden pallet because of big volume.
As for manufacture standard, it is different from other pipe fittings. Its standard is ASME B16.49.
Materials are carbon, alloy and stainless steel. Wall thickness in common use is STD, XS and so on. With the development of the society, steel bends are widely applied in oil & gas transportation of pipeline system.

[ China Agricultural Machinery Industry News ] One year is in spring. Spring ploughing and ploughing have always been the top priority for the crop earners to "race against time and plan closely." However, this year's Shijiao Village, Gaozhuang Township, Pingluo County, Ningxia Province, is famous for its diligent old man and horse making silver. In the spring ploughing, he stole a lazy and enjoyed leisure.
Cooperatives make efforts to "free work"
After lunch, until 1 o'clock, the reporter saw the horse in the ground to prepare for farming. He took a hoe and his footsteps were slow. There was no sense of urgency when he was ploughing for spring cultivation: "This place was overhauled last year and should not be cleaned up."
Ma Zuo Yinkou's overhauled land was sloppy, flat as a giant blanket stretched into the distance, and the water in the high channel next to it was rippling. However, when talking about the state of preparation before the land overhaul, Ma Zuo Yin’s words changed easily and filled with grievances: “You can toss people before they are repaired, not to mention the troubles of farming, and they will come to the air.â€
"In the past, half of the land could not be planted, and it was possible to plant a kind of 'a gourd to make a scoop'." Originally, this land used to be a bumpy saline-alkali land. The terrain was high and low, the ditch was heavily deposited, and the planting efficiency was very low.
"After the overhaul, the ground was flat, the ditch was unblocked, and the water level was low. I used to spend 3 days in the past. Now I have finished it in 2 hours. You said it is easy and relaxed." The comparison between the past and the present has made the horse feel silver, "still The villagers’ deliberation system is good and can mobilize the enthusiasm of the villagers.â€
Ma Zuoyin told reporters that the Gaoyiqu Agricultural Development Project, which was completed at the end of 2016, was originally completed in 2015. However, because the villagers were relatively passive when they were working, they ended up with a bad ending. In 2016, the villagers' congress was held in the village to pass the "capital for labor" system, so that the project was successfully completed, and he also had the "free leisure" when he was preparing for spring farming.
The reporter learned that "to do the work for the sake of labor" is to convert the labor day required for each employee's work in the village into money, and to collect and pay according to the land area of ​​each household of the villagers, and then return it through the work record.
"In the past ten years, there have been more and more migrant workers in the village, and there are fewer and fewer people relying solely on land income. The villagers have pocketed their drums, but they are not very concerned about the affairs of the village. If it is not the village democracy in recent years. Governance is deeply rooted in the hearts of the people, and the villagers are convinced of the resolution of the villagers' congress. We are really not well managed." Ma Yongjun, a branch secretary of Tongjin Village, said bluntly.
It is simple to level the land and irrigate the canal on the spring ploughing, but what about fertilizer seeds, planting plans, machinery rentals, etc? Ma Zuoying said with a smile: "There is a cooperative, I am still fucking."
He said: "My family is 30 mu of land. I am too busy to come to the cooperative to invest 20 mu. This 20 mu of land will not be taken care of by me. The cooperative will give 550 yuan per mu per year, and will be able to pay dividends at the end of the year."
At the end of 2011, the state listed Pingluo County as one of the pilot areas for the reform of rural land management system in the new round of rural reform pilot zone construction. In recent years, Pingluo County has continuously innovated, and various land transfer policies have not only revitalized the land economy, but also brought tangible benefits to the villagers. The establishment of the Tongjin Agricultural Service Professional Cooperative in 2016 is one of many achievements.
Although it has invested in 20 mu of land, the remaining 10 mu of land is still not a small amount for the 65-year-old Ma Zuo Yin. In this regard, Tongjin for the agricultural services professional cooperatives also provide farmers with four services such as agricultural materials distribution, agricultural machinery services, rural e-commerce, and forage recycling.
"In the past, I had to do a good job for a week or two. I spent a few days thinking about planting seeds, and then I bought the seeds and fertilizers. I sometimes ran back and forth for a few dollars for a bag of fertilizer. The rental machinery is more troublesome. Spend money to give people a good word and look at the face!" Talking about cooperatives, Ma Zuo Yin is endless. "Now three or four days! What kind of farming, how do I have professional guidance in townships and counties, use machinery? Say hello to the cooperative, the price is much lower than the market price!"
Ma Zuoyin calculated the account for the reporter: After the land overhaul, the irrigation cost of spring ploughing has been reduced this year, and the land use efficiency has also increased. This year, an acre of land is expected to average, and it can earn about 300 yuan.
