(1)原资料即带钢卷,焊丝,焊剂。在投入前都要经过严厉的理化检验。

(1) The original data are strip coil, welding wire and flux. Strict physical and chemical tests are required before investment.

(2)带钢头尾对接,采用单丝或双丝埋弧焊接,在卷成钢管后采用自动埋弧焊补焊。

(2) Submerged arc welding with single or double wires is used for butt joint of strip head and tail, and automatic submerged arc welding is used for repair welding after coiling steel pipe.

(3)成型前,带钢经过矫平、剪边、刨边,外表清算保送和予弯边处置。

(3) Before forming, the strip is leveled, trimmed, planed, cleared, delivered and bent.

(4)采用电接点压力表控制保送机两边压下油缸的压力,确保了带钢的平稳保送。

(4) Electric contact pressure gauge is used to control the pressure of the cylinder on both sides of the conveyor to ensure the smooth delivery of the strip.

(5)采用外控或内控辊式成型。

(5) Externally or internally controlled roll forming.

(6)采用焊缝间隙控制安装来保证焊缝间隙满足焊接请求,管径,错边量和焊缝间隙都得到严厉的控制。

(6) Weld clearance control installation is adopted to ensure that weld clearance meets welding requirements, pipe diameter, offset and weld clearance are strictly controlled.

(7)内焊和外焊均采用美国林肯电焊机停止单丝或双丝埋弧焊接,从而取得稳定的焊接标准。

(7) Both internal and external welding are performed by Lincoln Welding Machine to stop single-wire or double-wire submerged arc welding, thus achieving stable welding standards.

(8)焊完的焊缝均经过在线连续超声波自动伤仪检查,保证了100%的螺旋焊缝的无损检测掩盖率。若有缺陷,自动报警并喷涂标志,消费工人依此随时调整工艺参数,及时消弭缺陷。

(8) The welds after welding are inspected by on-line continuous ultrasonic automatic damage instrument, which ensures 100% coverage rate of non-destructive detection of spiral welds. If there is a defect, the automatic alarm and spraying mark, consumer workers can adjust the process parameters at any time to eliminate the defect in time.

(9)采用空气等离子切割机将钢管切成单根。

(9) Air plasma cutting machine is used to cut the steel pipe into single pieces.

(10)切成单根钢管后,每批钢管都要停止严厉的首检制度,检查焊缝的力学性能,化学成份,溶合情况,钢管外表质量以及经过无损探伤检验,确保制管工艺合格后,才干正式投入消费。

(10) After cutting into a single steel pipe, each batch of steel pipes should stop strict first inspection system, check the mechanical properties of welds, chemical composition, dissolution, appearance quality of steel pipes and non-destructive testing to ensure that the pipe-making process is qualified, and then formally put into consumption.

(11)焊缝上有连续声波探伤标志的部位,经过手动超声波和X射线复查,如确有缺陷,经过修补后,再次经过无损检验,直到确认缺陷曾经消弭。

(11) Where there is a continuous acoustic flaw detection mark on the weld seam, after manual ultrasonic and X-ray examination, if there is a defect, after repair, it is subjected to non-destructive inspection again until it is confirmed that the defect has been eliminated.

(12)带钢对焊焊缝及与螺旋焊缝相交的丁型接头的所在管,全部经过X射线电视或拍片检查。

(12) The tube where the butt weld of strip steel and the T-joint intersect with the spiral weld are all inspected by X-ray television or photography.

(13)每根钢管经过静水压实验,压力采用径向密封。实验压力和时间都由钢管水压微机检测安装严厉控制。实验参数自动打印记载。

(13) After hydrostatic test, the pressure of each steel pipe is sealed radially. The experimental pressure and time are strictly controlled by the installation and testing of the water pressure of the steel tube by the computer. The experimental parameters are printed and recorded automatically.

(14)管端机械加工,使端面垂直度,坡口角和钝边得到精确控制。

(14) The end of the pipe is machined so that the verticality, groove angle and blunt edge of the end face can be accurately controlled.
