Umumnya berbicara% 2c th diameter of the spiral steel tube can be divided into outer diameter% 2c diameter dalam diameter% dan nominal diameter. The outer diameter dari pipa adalah the luar diameter dari pipa dari dari spiral baja pipa is diwakili oleh the huruf D. The size and wall thickness of the outer diameter after the additional outer diameter, such as seamless steel pipes with 108 outer diameter, 5mm in wall thickness, expressed in D108*5, plastic pipes are also expressed, and plastic pipes also Use the outer diameter, such as DE63, other such as reinforced concrete pipes, cast iron pipes, galvanized pipes, etc. are expressed by DN. The nominal diameter adalah umumnya ekspres dalam desain gambar. A standar, yang adalah juga lebih julukan, adalah spesifikasi nama dari pipa (atau pipa).
The nominal diameter of the tube is different from its inner diameter and outer diameter. For example, there are several types of spiral steel tube mail with a diameter of 100mm 102*5, 108*5. 108 is the outer diameter of the tube. Therefore, the inner diameter of the steel pipe is (108*5-5)=98}mm, but it is not exactly equal to the difference between the outer diameter of the steel pipe. The specification name of a tube diameter, in the design drawing, must be used in the nominal diameter. The purpose is to determine the structure size and connection size of the structure of the pipe, pipe, valve, flange, pads, etc. according to the nominal diameter. If the outer diameter representation is used in the design drawings, the pipeline specifications should also be made to indicate the nominal diameter and thick wall of the nominal diameter of a pipeline.
Cara untuk transportasi cairan spiral baja pipa cara untuk mencapai energi penghematan
The conveying fluid pipe seized the seasonal changes with decreased temperature in late autumn, and took a reasonable start -stop cooling tower to run the fan and the work measures used to cool down the pump room to effective reduce the power consumption. According to the calculation of the professional management department, only this item can reduce the cost of nearly 100,000 yuan per month.
Dalam harian produksi dan operasi% 2c ada are 15 (set) pendinginan menara pesawat berjalan at the sama waktu% 2c dan total daya is as tinggi as 1600kW per jam% 2c yang is a veritable tukang listrik. Karena the pembuatan baja sistem dan the kontinu casting sistem memiliki khusus persyaratan untuk pasokan dari air medium, terutama kapan peleburan butik baja jenis, the kontrol dari air agensi suhu perbedaan bermain a vital peran dalam stabil produk kualitas dan pengembangan dari baru baja spesies.
Dalam penambahan% 2c Anda dapat juga menggunakan perubahan di luar ruangan suhu ke cukup menghidupkan dan berhenti kipas untuk mencapai tujuan dari mengurangi daya konsumsi dan penghematan energi. Ambil inisiatif ke kontak masing-masing produksi baris pengguna% 2c di kedalaman pemahaman dari spesifik untuk air suhu 2c menentukan sebagian sebagian masuk akal rentang% 2c dan mencapai tujuan dari mengurangi biaya dan efisiensi sementara pertemuan kebutuhan dari produksi produksi.
Make full use of the characteristics of seasonal changes and decreased outdoor temperature at night, and adopt the method of tracking the data of the temperature change data of the water medium at the production site in real time, and adjust the operating fan in a timely manner to minimize the number of fans. For a week, the number of fans running has been dibelah dua, and the power consumption has also berkurang sebesar setengah.
