API 11B Sucker rod centralizer / Sucker rod guide material PA66 /
PPA Resin
Product application:
Sucker rod centralizer is a kind of downhole tools which is pumping
well anti-abrasion, it is especially suitable for pumping well and
directional well whcih above of sucker rod middle point,under the
middle point of sucker rod , the rod body with nylon centralizer is
works better.
The sucker rod moves up and down in the tubing, due to the elastic
deformation of sucker rod, rod and oil tube wall is easy to make
friction, ti makes sucker rod break off easily, sucker rod
centralizer has strong flexibility, touched with the tubing wall
can reduce the friction of rod and tube, and can be increase
production life of pumping unit. The centralizer is connected with
sucker rod , the outsid diameter of centralizer is bigger than
coupling outer diameter,so that can make the function of
centralize. The centralizer is made of high strength wear-resistant
material, and touched with the tubing to reduce the abrasion to
achieve the purpose of anti-abrasion.
Chemical composition:
Process Sucker Rod Centralize:
1.Precondition: To ensure that the temperature of the workshop is
not less than -20℃.
2.Drying: the raw material is dried in 100℃ hot air, making its
humidity less than 0.1%.
3.Equipment debugging: power and water supply of equipment,then
install the mould, cleaning equipment and raw material barrel.
4.Raw material melt: the melting temperature of HTN51G35HSLR.
5.Mold temperature: the mold temperature of the processed
HTN51G35HSLR material is 145℃, and the mold temperature of the
processed HTN53G50HSLR is 100℃.
6.Processing: the nozzle temperature is 290 ℃, plasticizing area
one temperature is 285 ℃,plasticizing area two temperature is 275
℃, plasticizing area three temperature is 260 ℃, injection pressure
is 110 bar, flow is 90 cc/min.
7.After the first product is produced, it will be testing the size,
and the batch production will be start after the testing.
