貴州鑄造有限公司告訴你鑄鐵管的螺紋安裝方法;

貴州鑄造有限公司

Guizhou Foundry Co., Ltd. tells you how to install the thread of the cast iron pipe;


貴陽鑄鐵管在切割以后,為了方便連接和使用,需要在貴州鑄鐵管的一段套上螺紋,一般選用的鏈接用的管道螺紋是英制的55°的管螺紋。安裝的時候使用的各種連接的零件都是由廠家根據專業的標準,制造的與螺紋配套使用的零件。一般情況下會將管端加工成圓錐形的螺紋,可以增強防水效果。

After the Guiyang cast iron pipe is cut, for the convenience of connection and use, we need to thread on a section of Guizhou cast iron pipe. The pipe thread commonly used for connection is British 55 degree pipe thread. The parts of all kinds of connections used at the time of installation are made by the manufacturer in accordance with the professional standards. In general, the tube end will be processed into a conical thread, which can enhance the waterproof effect.



貴州鑄造有限公司在安裝螺紋的時候,首先要保證螺紋是端正的,沒有偏扣、亂扣的現象,還要保證螺紋是光滑的沒有毛刺。如果有缺口和斷口,那么長度要求不超過螺紋全場的十分之一,否則就會影響使用。而且,選擇的螺紋需要有一定的錐度,松緊的程度要適中,套好之后可以進行試擰,一般以空手擰2-3圈為宜。如果太松了就會影響密封的效果,太緊了就會使閥門脹裂。所以在安裝螺紋的時候應該注意松緊度。螺紋接好后,最好在外面露出來兩三扣備用。

Guizhou Foundry Co., Ltd., when installing thread, first ensure that the thread is correct, there is no phenomenon of partial buckle and buckle. It is also necessary to ensure that the thread is smooth without burrs. If there is a gap and a fracture, the length should not exceed 1/10 of the whole thread of the thread, otherwise it will affect the use. Moreover, the selected thread needs a certain degree of taper, the degree of tightness should be moderate, and the test can be made after the set is set well. It is suitable for 2-3 circles to be unscrewed by empty hands. If too loose will affect the sealing effect, too tight will make the expansion valve. Therefore, when installing the thread, we should pay attention to the tightness. After the thread is connected, it is best to reveal two or three buckles out of the outside.


缺點:用于缺陷修復,小缺陷修復時(氣孔、砂眼),因沖擊過大,熔池邊線有痕跡。焊補鋼件有硬點。由于熱影響,焊補有色鑄件或薄壁件時,易產生熱變形。操作技術要求較高。

Disadvantages: for defect repair, repair of small defects (pores, trachoma), due to the impact of large pool edge trace. Welded steel parts have hard points.  Because of the heat effect, it is easy to produce hot deformation when welding coloured castings or thin-walled parts. The requirements of operation technology are higher.


冷焊機:是21世紀初新誕生的修復技術,因焊補過程中工件產生熱量極小,被成為冷焊機。經過幾年的發展,焊機應用方向和技術都得到了很大的發展,已經在修復市場占有很大的份額。按照修補產品分類有:貼片機和電火花堆焊修復機。

Cold welding machine: it is a newly born repair technology in the early twenty-first Century. Because of the small heat generated by the workpiece during the welding repair, it has become a cold welding machine. After several years of development, the application direction and technology of welding machine have been greatly developed, and it has a great share in the repair market. According to the repair product classification: the patch machine and the electric spark surfacing repair machine.
