但（dàn）凡做鋼材的話都是知道冷拔無縫鋼管是鋼管的（de）一種精細度比較大（dà）的一種鋼管類型（xíng），它的用處也是十分廣泛的，尤其是冷拔無縫（féng）鋼管的各種的性能以及各種的用處都（dōu）是比較重（chóng）要的一種冷拔無縫鋼管的（de）表（biǎo）現。精細管在進行運用的話要清晰精細管的運用的性質（zhì）和各個方麵（miàn）的用處，做到精細管的合理運用。精細管是冷拔鋼管（guǎn）的（de）一種特別的情況，也（yě）是一（yī）種良好的鋼材，可（kě）以說是精細管的原料也是比較特別的，運用量和市場前景都是比較大的。
But when making steel, we all know that cold-drawn seamless steel pipe is a kind of steel pipe with high fineness, and its use is also very extensive, especially the various properties and uses of cold-drawn seamless steel pipe are more important performance of a cold-drawn seamless steel pipe. Fine tube in the use of words to clarify the nature of the use of fine tube and the use of all aspects, so that the rational use of fine tube. Fine pipe is a special case of steel pipe, and also a good steel. It can be said that the raw material of fine pipe is also special, and its application and market prospects are relatively large.
冷拔無縫鋼管是一種通過（guò）冷拔（bá）或熱（rè）軋處理後的一（yī）種高精細的鋼管資料。因為（wéi）精細鋼管（guǎn）內外壁無氧化層、承受高（gāo）壓無泄漏、高精度、高光潔度、冷彎不變形、擴口（kǒu）、壓扁無裂縫等有點，所以主要用來出（chū）產（chǎn）氣動或液壓元件的產品（pǐn），如氣缸（gāng）或油缸，可以是冷拔無縫鋼（gāng）管，也有焊接管（guǎn）。精細（xì）鋼管（guǎn）的化學成分有碳C、矽Si、錳Mn、硫S、磷P、鉻Cr。
Cold-drawn seamless steel tube is a kind of high-precision steel tube material after cold-drawn or hot-rolled treatment. Because there is no oxide layer on the inner and outer walls of fine steel pipes, no leakage under high pressure, high precision, high gloss finish, no deformation in cold bending, flattening and no cracks, etc., it is mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes, as well as welded pipes. The chemical composition of fine steel pipe is carbon C, silicon Si, manganese and manganese, sulfur S, phosphorus P, chromium and chromium.
常用原料：
Raw materials:
可出產的原料則（zé）許（xǔ）多，鋼隻要是不太硬，基本都可根據需要進行出產。如：10#，35#，16Mn，40Cr.
There are many principles for producing raw materials. As long as the steel is not too hard, it can basically be produced according to needs. For example: 10, 35, 16Mn, 40Cr.
製作程序是比較繁瑣的，出產的狀況也是比較好的，性能是比較優勝的，在運用上也是（shì）不斷地進（jìn）行發揮出來良好地效果的（de），因此的話精細管從某種意義上來說是（shì）一種良好的鋼材類型。
The production process is more complicated, the production situation is better, the performance is better, and the application is also constantly playing out good results, so the fine tube is a good steel type in a sense.
