What is the elbow?

In a piping system, an elbow is a pipe that changes the direction of the pipe. According to the angle, there are three most commonly used 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs.

Elbow China are made of cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. The way to connect with the pipe is: direct welding, flange connection, hot melt connection, electrofusion connection, screw connection and socket connection. According to the production process, it can be divided into: welding elbow, punching elbow, push elbow, casting elbow, butt weld elbow.

Other names: 90° elbow, right angle bend, love and bend.

Uses: Connect two pipes with the same or different nominal diameters to make the pipeline turn 90°, 45°, 180° and various degrees.

Technical requirements: 1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are all turned into bevels, leaving a certain angle with a certain edge. This requirement is also stricter, the thickness is thicker, the angle is how much and the range of deviations are specified. The surface quality and mechanical properties are basically the same as the tube. For the convenience of welding, the pipe is the same as the steel of the pipe to be connected.

2. All the pipe fittings must be surface treated, and the iron oxide skin on the inner and outer surfaces is sprayed off by shot peening, and then coated with anticorrosive paint. This is for export needs, and in addition, in order to facilitate transportation and prevent corrosion and oxidation in the country, we must do this work.

3, The requirements for packaging for small pipe fittings, such as exports, you need to do a wooden box, about 1 cubic meter, the number of elbows in this box is not more than one ton, the standard allows the suit, that is, a large set. However, the total weight can not exceed 1 ton. For large pieces, a single package is required, such as 24", it must be a single package. The other is the package mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.

Summer Solstice is coming

As a Pipe Fitting Manufacturer, today we would like to share you the Summer solstice in ear (one of the 24 solar terms) for you.

Summer solstice, east wind shaking, wheat dragged from water

Summer solstice, southeast wind coming, flat land boating

The winter solstice began to frost, the summer solstice dried Yangtze River

The winter solstice in south is short, the summer solstice is dry and hot

The east wind shakes in Summer solstice, the wheat sits in the water

                                                      

 It immediately ushered in the longest day of the day in the year. On the summer solstice, the position of the sun directly on the ground reaches the northernmost point of the year, almost directly to the Tropic of Cancer. The shadow is the shortest, the longest in the day, and the shortest in the night, as the ancients said: "The day is long, the shadow is short, to the extreme, too, so the summer solstice."

The hottest time in summer is coming. People should pay more attention to sunscreen, especially the working people. This season is the most sweaty time, more water is needed. We are WH-steel, the Carbon Steel Tee and Reducer Manufacturer. Pay tribute to all the hardworking staff of our WH-steel.

Iron and Steel Smelting Process of Ancient China

As a Pipe Fitting Manufacturer China, today we would like to share with you the iron and steel smelting process in ancient China.

China's artificial smelting iron is later than the two river basins in West Asia and Egypt. According to the existing records and the investigation of unearthed cultural relics, it can be traced back to the Spring and Autumn Period, and the early legends and speculations are not very reliable. 《Zuo Zhuan》records that during the Spring and Autumn Period, Zhao Guo, a native of Jin Dynasty, led the army to Rubin, where he was charged with iron levy. He cast a penalty tripod, which cast a book of Fan Xuanzi's criminal book.

   The book《Guan Zi》was recorded: "All the world famous mountains 5,371,... The mountain of the Iron mine is three thousand six hundred and nine. In the Eastern Han Dynasty, Zhao Ye’s 《Wu Yue Chun Qiu》said: during the Spring and Autumn Period, Wu Wang He Lv appointing craftsman Gan Jiang smelt "the iron of the five mountains" and forged the sword. With the help of his wife Mo Ye, he finally made two sharp famous swords. Those records are of great value.

 

    From the unearthed cultural relics, the earliest iron smelters that have been artificially smelted so far can be exemplified: the iron-handed copper swords were unearthed in Lingtai, Gansu, in the late spring and autumn; the iron-iron bars and pig iron pills in the late spring and autumn were unearthed in Chengqiao, Liuhe County, Jiangsu Province; The pig iron shovel (锹) was unearthed at the Tomb of the literacy in Changsha; the iron tripod which cast by Chu State was unearthed in the Changsha Yaoling Mountain. In terms of time, it is roughly consistent with the literature.

At an earlier time, our ancestors had been exposed to ferroniobium, but that was not artificial smelting. For example, in 1972, a bronze plaque was unearthed in the middle-aged site of the Shang Dynasty in Taixi Village, Rucheng County, Hebei Province. It was engraved with an iron blade. After scientific appraisal, it was cast into the gong by the enamel iron.

   So how do you identify the siderite and smelting iron? The main basis is two: one is that ancient artificial smelting iron must contain more silicate inclusions, but not in ferroniobium. Second, siderite always contains a high content of nickel (about 5%) and some cobalt, the content of nickel and cobalt in iron is high and low phase distribution.

Modern China's steel forging process has also reached the world's advanced level and has always been in line with international standards. WH-Steel Co., Ltd. specializes in the production of excellent flanges, elbows, barred tee, carbon steel and other pipe fittings. We cooperate with the global countries to provide a variety of pipe fittings. Welcome friends to come to consult.
