チューブ・パイプ製造における非接触測定

Polytec optical sensors are widely used in tube production, measuring tube / pipe speed, for position tracking or NDT, laser precise cut-to-length control and in general for non-contact length and speed measurement. LSV (short for Laser Surface Velocimeter) monitor length and material on longitudinally welded pipes and also reliably measure the rotational speed of seamless pipes. Avoid process uncertainty and added costs introduced by contact measuring techniques due to slippage, wear, damage to the product or increased maintenance requirements.

チューブ＆パイプのプロセス制御に光センサーを使用する理由

ProSpeed® LSV (short for Laser Surface Velocimeters) are the ideal non-contact sensor solution in tube and pipe manufacturing, whenever precise and real-time speed and length data is decisive. Using optical sensors in pipe production leads to reduced costs due to less material scrap and optimized process quality. 

ProSpeed® optical sensors are easily integrated replacing less accurate and less reliable encoders or tachometers for tube and pipe production. Savings in reduced downtime and maintenance as well as increased product consistency provide an excellent ROI on Polytec optical sensors.

ProSpeed®センサーによる光学測定のメリット

  • Reliable in-line measurement of length, speed and standstill
  • Optical encoders avoid contact, slippage and wear
  • High flexibility with up to 3 m long stand-off distances
  • Outstanding measurement depth-of-field up to 200 mm compensates varying distances
  • Robust sensor technology for harsh and hot environments (IP66 and IP67); certified mechanical shock and vibration resistance

Strong in service: Onsite, 3yrs warranty, sensor exchange

Applications of optical sensors in steel tube processes

There are many measurement applications for Polytec LSV laser sensors in the production of (stainless) steel pipes and related tubes: 

  1. Monitoring and synchronizing the coil feed speed in the forming section
  2. Pipe speed measurement in welding
  3. Superior cut-to-length control directly reduces scrap and optimizes yield
  4. Position tracking and crop shear control in the stretch reducing mill
  5. Precises pipe speed monitoring through the temper / quench area
  6. Defect tracking in NDT (Non-desctructive Testing)
  7. Final length control and length verification at the stencil area.

ビデオ その仕組み 信頼性の高いプロセス制御のためのレーザー精度

ProSpeed® as the optical alternative sensor solution compared to encoders or encoder wheels use the laser Doppler effect to evaluate the laser light scattered back from the moving object. Two laser beams super-imposed on the surface generate an interference pattern of bright and dark fringes. As the surface moves through the fringe pattern, the intensity of the light scattered back modulates in frequency. This modulation frequency measured by the photo receiver of the sensor system is directly proportional to the surface velocity.

シームレス鋼管の非破壊検査

During NDT the tube should be tested to 100% regarding e.g. metallurgical properties and length. The probe conducting this test is stationary, hence the tube is not just pushed forward, but it also rotates on a spiral path. Any flaw detected needs to be described in its longitudinal and rotational position. Here, non-contact LSV laser sensor comes into play: Being insensitive to out-of-plane motions, it is the preferred optical solution for such setups. One unit keeps track of the longitudinal progress while a second unit monitors the rotation. Specialized accessories for such demanding application master electromagnetic inspection (E.M.I.), magnetic powder inspection (MPI), and other test methods.
