In Detail:

Z

The sheet steel used for blind pipe manufacture is S23JR, 3-6mm thick, in single pieces up to six meters. The pipes are measured in accordance to API 5A. Blind pipes are longitudinally welded ER/HFW (Electric Resistance/High Frequency Welding) as per DIN 1626/2458 – EN 10219 or Mig-Pulse welded.

Z

The bridge type slotted screens manufactured as per DIN 4922 are made for longitudinally welded base pipes ER/HFW (Electric Resistance / High Frequency Welding) as per DIN 1626/2458 – EN 10219 or made for Mig-Pulse welded pipes. The screen sheet steel is of S235JR, 3-6mm thick in single pieces up to six meters. The pipes are measured in accordance to API 5A. The filter’s bridges and slots start from 25cm from the welding point of the female connector and 20 cm from the welding point of the male connector. The opening of the bridge is 1,00 m/m to 3,00 m/m. Diameters 4 ½”, 5 1/4 ”, 6 5/8, 8 5/8, 10 ¾, 12 ¾, 14΄΄, 16΄΄, 18΄΄ refer to external diameters without the filter or slot of the tube. The free surface is at least 10% of the filtered segment.

Z

The connections of pipes and screens are manufactured under European specifications. They have semicircular thread with 2 coils/inch and a depth of at least 70 m/m from the edges. Their length is at least 100 m/m to 120 m/m and their thickness varies from 12m/m up to 15 m/m.

Z
