無縫管材是地質勘探部門鑽探工程中主要材料之一。我局每年所需的數量約佔鋼鐵材料的50％。由於使用量多損耗量大,每年報廢的管材數量也不少。1956年一至三季“待報廢數”之和相當於三季末庫存結轉數的1/3,相當於1956年供应數的24％。這些報廢的管材過去大多當作廢鋼處理了。在目前鋼材缺乏(特别是管材)的情況下,很好的利用廢管材來代替送風管送水管,不僅可以解决原材料供應不足的困難,而且還能為國家節約鋼材和資金。 為了研究此一方法,我們曾會同部供應局,前往105勘探隊進行了關於用廢管代替送水管,送風管的試驗工作。實踐證明:報廢的地質管材用作送 Seamless pipe is one of the main materials in the drilling engineering of geological exploration department. The amount required by the Bureau every year accounts for about 50% of the steel materials. Due to the large amount of use loss, the number of pipe scrapped each year is also quite a few. The sum of “waiting for scrapping” in the first three quarters of 1956 was equivalent to 1/3 of the number of inventory carried forward at the end of the third quarter, equivalent to 24% of the supply in 1956. Most of these scrap pipes were treated as scrap steel in the past. In the current situation of the lack of steel (especially pipes), the good use of waste pipe to replace the air supply pipe, not only can solve the difficulties of raw material supply, but also save the country steel and funds. In order to study this method, we used the same Department Supply Department to go to the 105 exploration team to conduct trial work on the use of waste pipes instead of water supply pipes and air supply pipes. Practice has proved that: the abandoned geological pipe is used as a delivery
