The main function is to further roll the coarse pipe that is produced by the hole-punching machine and to change the pipe shape so that primary pipe completed. The machine is an ASSEL rolling machine with 3 rollers. It is not noly suitable for increased wall thickness seamless pipes but also for small thickness pipes it is also a high precsion equipment (The tolerance can be ±5%). The machine is the most advanced in the world too.
步進爐 Walking furnace
即再加熱爐，主要功能是將荒管再次加熱到規定的溫度，為下一道工序做好準備。該步進爐具有加熱快，加熱溫度均勻、加熱鋼管基本無燒損等優點。
It is a further heating furnace. The main function is to heat the primary pipe to setted temperature for the next process. The advantages are heating quickly and evenly with almost no rejection of pipes because of burning.
減徑機 （定徑機）
Diameter-decreasing machine
The main function is to roll the primary pipe so that the shape changes again and meets the size that is in accordance with technical requirements. the machine comprises 18 small-lensile-force diameter decreasers. It is the most mature tensile force diameter reducing equipment in China. It is rigorous specitication is that it can produce high precise size and size and wall thickness and small ends cut .
冷床 Cooling bed
The main function is to cool the hot steel pipe to less than 150℃ . The cooling bed can cool the pipe evenly and low cambering rate .
矯直機 Straightener
The main function is to straighten the pipe in normal temperature so that the straightness meets technical requirements. the machine adopts PLC controlling system . The pipe can be fed-in and come out automatically and auto matically adjusts so that pipe straightened machine works very efficiently and stably .
熱處理淬火爐、回火爐
Quenching Tempering furnace熱處理生產線包括兩台淬火爐和兩台回火爐，熱處理淬火爐和回火爐具有正火、淬火+回火、正火+回火的功能。該生產線是以天然氣座位清潔能源，採用先進的脈衝燃燒技術，具有高產、優質、低消耗及生產操作自動化等優點，可生產N80-QL80、P110等高剛級、抗擠毀系列油套管產品，提高了油套管的剛級性能。
The heat treatment line includes two quenching furnaces and two tempering furnaces. which is used to normalizing , quenching & tempering and mormalizing & tempering . The line Uses natuvantages are high efficjency , low energy consuming high quality and high automatization . ect. The line is suitable for upgrading the high steel grade and high collapsing resistant OTCG such as N80-Q P110 ect. because it is capable to improve the steel's properties.
