The requirements for the installation of galvanized steel pipe for Guiyang hot-dip galvanized steel pipe pin;


硬度是衡量金屬材料軟硬程度的指針,貴陽鍍鋅鋼管廠目前生產中測定方矩管硬度的方法最常用的是壓入硬度法,它是用一定幾何形狀的壓頭在一定發的載荷下壓入被測試的金屬材料表麵,溫州鍍鋅鋼管廠根據被壓入程度來測試其硬度值。

Hardness is a measure of the pointer degree of soft metal materials, Guiyang galvanized steel pipe factory in the production method of square pipe hardness indentation hardness is the most commonly used method, it is with a certain pressure head geometry in certain load the pressure into the metal surface to be tested, according to the Wenzhou galvanized steel pipe factory is pressed into the to test the degree of hardness.


巴音郭楞大家看 製度 2.執行標準:GB/T6728-2002,7KY977Cdq0OHN貴陽鍍鋅鋼管廠ASTM,貴陽鍍鋅鋼管廠JIS或技術協議。1.以上方矩管可做直縫方矩管及無縫方矩管,比如網上原文新聞內容是: 2016年5月15日,特殊規格可定做加工。

Bayinguoleng people see the system 2. implementation standards: GB/T6728-2002, 7KY977Cdq0OHN Guiyang galvanized steel pipe factory ASTM, Guiyang galvanized steel pipe factory JIS or technical agreement. 1. the square rectangular tube and seamless square tube, such as the original news content on the Internet, can be processed by the special specification in May 15, 2016.


安裝材料表 3.方矩管材質:235B,以HBS(鋼球)表示,Q345(B,試樣在拉伸過程中力不增加(保持恒定)仍能繼續伸長時的應力,C),16Mn,20# ,45#,20MN2.檢驗要求 項目範圍 鍍鋅鋼管分為冷鍍鋅鋼管、熱鍍鋅鋼管,冷鍍鋅鋼管已被禁用,貴陽鍍鋅鋼管廠後者還被國家提倡暫時能使用。

Installation material table 3. square tube material: 235B, HBS (ball), Q345 (B, the specimen in the process of tensile force does not increase (constant) can still continue to stress elongation, C), 16Mn, 20#, 45#, 20MN2. inspection requirements the scope of the project is divided into cold galvanized steel galvanized steel pipe pipe, galvanized steel pipe, cold galvanized steel pipe has been disabled, Guiyang galvanized steel pipe factory was also the latter state advocates can use temporarily.


扶餘縣六七十年代,交貨狀態編輯 是指交貨產品的最終塑性變形或最終熱處理的狀態。溫州鍍鋅鋼管廠國際上發達國家開始開發新型管材,並陸續禁用鍍鋅管。中國建設部等四部委也發文明確從二000年起禁用鍍鋅管作為供水管,新建小區的冷水管已經很少使用鍍鋅管了,有些小區的熱水管使用的是鍍鋅管。

Fuyu County 60s and 70s, delivery state editing refers to the final plastic deformation or final heat treatment of delivery products. The Wenzhou galvanized steel tube plant has been developing new types of pipes in the developed countries in the world, and galvanized pipes have been banned in succession. China's Ministry of construction and other four ministries and commissions have also been civilized. Since the two 000 years, the galvanized pipes have been banned as the water supply pipes. The cold water pipes in the new residential districts have rarely been used for galvanized pipes, and some hot water pipes in some districts are galvanized pipes.
