精軋（zhá）無縫鋼管使用（yòng）新技術、冷拔方法生產高（gāo）精確程度冷拔無縫鋼管（guǎn）──滾壓缸體（tǐ）與較為傳統的持續（xù）切削生（shēng）產工藝進行比（bǐ）較，精軋（zhá）無縫（féng）鋼（gāng）管具備這陣兒主要特點：製造效率高：用較為傳統的辦法（fǎ）生產關於（yú）一根內徑420螺絲帽，12米長（zhǎng）的（de）缸筒（tǒng）需154鍾頭，用冷（lěng）拔辦法生產隻需（xū）4毫秒。正（zhèng）品率高：因為鏜孔的滾（gǔn）壓頭（tóu）兼起引向實際作用，在持續切削完整過程中（zhōng），毛坯管因為（wéi）尊（zūn）重形成撓度，造（zào）成（chéng）滾壓頭和（hé）鏜刀走偏，導致廢物，正品率（lǜ）隻得實現60%身邊人，而（ér）用冷拔辦法生（shēng）產，正品率可達95%上述（shù）。
Compared with the traditional cutting process, the finishing steel pipe has the following characteristics: high production efficiency: 420 mm inner diameter, 154 hours for 12 meters long cylinder and 4 minutes for cold drawing. High rate of genuine products: Because the boring rolling head plays a guiding role, in the cutting process, because of the deflection of the blank tube due to self-weight, the rolling head and boring cutter deviate, resulting in waste products, the rate of genuine products can only reach about 60%, while the rate of genuine products produced by cold drawing method can reach more than 95%. 精（jīng）軋無縫鋼管（guǎn）能改進產品管非金屬的機械使用性能：用進行繪（huì）畫辦法生產，使毛坯獲得30%上述的塑性變形蛻（tuì）變，因為進行加工（gōng）動脈血管硬化而使產品管非金屬的極限抗拉強度限極為使原有水平上升，通常在產品缸管層極限抗拉強度限使原有水平上升達60%。高精確程度冷（lěng）拔管是用無（wú）縫熱軋無縫鋼管、直縫焊管為毛坯，經曆化學解（jiě）決後在（zài）特地冷拔有關機上，借助（zhù）異常蛻變規（guī）律（lǜ）設計的胎具開展（zhǎn）進行繪畫，生出現高精確程（chéng）度管。
Finished steel pipe can improve the mechanical properties of finished pipe metals: by drawing, more than 30% plastic deformation of the blank can be obtained, and the strength limit of finished pipe metals can be greatly increased due to work hardening, generally up to 60% in the inner strength limit of finished pipe. High-precision cold-drawn pipe is made of seamless hot-rolled steel pipe and straight welded pipe. After chemical treatment, it is drawn on a special cold-drawn machine through a die designed by special deformation principle, and high-precision pipe is produced.
精軋無縫（féng）鋼管是其中一（yī）種新式高技術減少能耗主要特點，,高精確程度冷拔著名無縫鋼管的進行推廣投入實際使用對厲行節約鋼鐵，使原有水平上升進行加工工效，厲行節約可（kě）用能源更加所謂高精（jīng）確程度冷拔無縫無縫鋼管（guǎn）是指內、外徑度量衡精確程度(衙役適用範（fàn）圍)從嚴（yán），裏裏外外（wài）要樣兒重（chóng）要度、圓度、直度較好。
Finish-rolled steel pipe is a new type of high-tech energy-saving feature. The popularization and application of high-precision cold-drawn precision steel pipe can save steel, improve processing efficiency and save energy. The so-called high-precision cold-drawn seamless steel pipe refers to the strict dimension accuracy (tolerance range) of inner and outer diameters, and good surface finish, roundness and straightness.
