制冷工程的好材料-紫銅管(一)

作者:匿名    訪問量:2696    發布時間:2013-09-15

我公司是以生產、銷售、維護紫銅管為一體的公司,近年來公司不斷發展技術力量,創新生產技術手段,生產的產品銷往全國各地,受到客戶的一致好評,今天讓大家了解一下制冷工程的好材料紫銅管:
制冷工程常用管材有鋼管和銅管兩類。鋼管又分為無縫鋼管和焊接鋼管兩種。無縫鋼管的特點是質地均勻、強度高、易于加工、內壁光滑,有熱軋和冷拔之分;焊接鋼管又稱有縫鋼管,按其表面處理與否有鍍鋅管和不鍍鋅管之分。制冷工程中常使用熱軋無縫鋼管。銅管又分為純銅管和黃銅管兩種。-純銅管的特點是質軟、易彎曲加工、耐腐蝕、管壁光滑,但強度稍弱。制冷系統中較多使用純銅管。
  (1)氟里昂制冷系統的管材常用紫銅管或無縫鋼管,一般管徑小于25mm時用紫銅管,管徑較大時,用無縫鋼管。氨制冷系統則全部采用無縫鋼管,當工作溫度低于-40℃時采用低合金鋼管;鹽水管壓力不高,可采用鍍鋅鋼管;冷卻水管一般也采用鍍鋅鋼管。
  (2)當紫銅管采用燒紅退火時,管內易產生氧化皮,為清除氧化皮,可用鐵絲綁上棉紗并浸上汽油,反復拉洗,隨時用汽油清洗棉紗,直至拉洗干凈為止。
  (3)氟里昂及氨制冷裝置的閥門、安全閥、壓力表等,都是專用的,由廠家配套供應,不可隨意取代。(圖/文www.startamils.com)

Our company is the production, sales, maintenance of copper for the whole company, the development of the company technical force is constantly in recent years, technology innovation and production, products are sold throughout the country, by the customer the consistent high praise, today let everyone know about good material copper refrigeration engineering:
Commonly used pipe refrigeration engineering steel pipe and copper pipe two class. Steel pipe is divided into seamless and welded steel pipe two. Characteristics of seamless steel tube is uniform texture, high strength, easy processing, smooth inner wall, with hot rolling and cold drawing of welded steel pipe; also called seamed steel pipe, according to its surface treatment and whether there is galvanized pipe and non galvanized pipe branch. Hot rolled seamless steel tube used in refrigeration engineering. Brass is divided into pure copper and brass tube two. The characteristics of pure copper tube is soft, easy to bend processing, corrosion, wall smooth, but the intensity is weaker. The refrigeration system uses more pure copper tube.
(1) of freon refrigeration system pipe commonly used copper tube or seamless steel tube, the general diameter of less than 25mm with copper pipe, large diameter pipes, seamless steel pipe. Ammonia refrigeration system with seamless steel tube, when the temperature is lower than -40 ℃ using low alloy steel; brine pipe pressure is not high, can be made of galvanized steel pipes; the cooling pipe is also generally used galvanized steel pipe.
(2) when copper by burning annealing, easy to produce oxide skin tube, for the removal of oxide skin, use wire tied with cotton dipped in gasoline and repeatedly washed, at any time, gasoline cleaning cotton, until the pull clean so far.
(3) the Freon and ammonia refrigeration device of valve, safety valve, pressure gauge, is dedicated, by supporting manufacturers supply, can not be replaced.
