Bu using friction welding and forging technologies, we produced high tensile strength, %100 watertightness and easy installation submersible pump column/riser pipe.
**Chemical heat treatment**
We use the technology that increases the wear resistance of the thread in dozens of times.
Completely eliminates
The coupling (box) is fixing by friction connection method. This friction method is forming defrostand and hot rolling simultaneous operation ,because of these reasons friction welding rupture is impossible.Other welding methods(submerged arc welding, inert-gaswelding, electrod eweldingetc.) weld by consumingly the wall thickness damaging.If we compare the rupture between friction welding and other methods, we can say 4mm friction welding is equivalent to 6mm other methods as welding pipe. Friction welding technology used in air craft industry, OCTG industry, defense industry, automotive industry and other special application. Frictionwelding is unrivaled…
Friction welding is not a welding method, is a joining by hot rolling.
Column Pipes are threading to upseted (thickened) area accordingto API standards.
Significance of watertightness;
Sealing o-ring is used on column pipes for ultra sealing even tolerate the mistakes in the course of assembling .Column pipes do not sealing on 50 bar water test.
On submersible pump system , efficiency is calculating according to %100 sealing. Leakage always consists on join area of column pipes. For this reason required feature is watertightness from column pipes. These leakage effects pump system %8 - %20 of efficiency. This means that, to get equal to water , %8 - %20 extra paid electric bill.
Water leakage at joining of column pipes threads will decay from column pipe threads area. In a short time distortion at joining of column pipe threads will cause to rupture from threads. This situation will be big cost and big trouble.Drilling well becomes unusable .Our Zeroing Column Pipes do not seal , do not drip under 50 Bars water pressure.
A chain is only as strong as its weakest link…
The threaded ends of the pipe wall thickness increase %100 as against to pipe body wall thickness and so increasing the srength of thread. Remaining wallthickness from end of threads is higher than the others.
If describe the Column Pipes string as a chain rings, threaded area is as chain link.
List the advantages of Zeroing Column Pipes
*Our Zeroring Column pipes do not leak and pump system efficiency does not loose.Energy cost reduce.
*There is no lekage on connection threads.Because of that, deformation and molding non-occurrence on threads.
*The pin end of column pipes wallthickness is %100 as against to pipe body wall thickness.Because of that, in swagger downhole there is no load on threads and in all conditions threads protect and no lekage on connection threads.
*Assemblying of Zeroring Column Pipes is easy than others and shorten the time %50.
*Selecting the different wallthickness and different composition of raw material , available for geotermal deep well pumps.
* in comparison to other column pipes, zeroing column pipes are low-cost and highly productive.
All pin sides of Zeroring Column Pipes has heat treatment for anti galling.
