Some specific solutions have been developed, targeted<br />
to increase rod string duration and performance.<br />
Rod Guides<br />
<strong>Tenaris</strong> has a wide range of centralizers and materials, both<br />
for beam pumping and PC pumping, which provide an<br />
effective wear control.<br />
Centralizers are molded onto rods, with the necessary grip<br />
for decreasing the displacement probability, thus becoming<br />
a real tubing and rod protection.<br />
When combined with the use of rod rotators, they also permit<br />
an effective paraffin control. It has been proved that its use in<br />
wells significantly increases tubing and rod run life and reduces<br />
their wear, consequently diminishing pulling interventions and<br />
other operating costs.<br />
Sinker Bars<br />
This element is necessary to<br />
maintain an optimized string<br />
design in order to avoid early<br />
rod failures. It is very effective<br />
to reduce pin and coupling<br />
failures generated due to the<br />
effect of string compression.<br />
Sinker bars are usually located<br />
at the end of the string, over<br />
the pump, in order to keep it<br />
fully under tensile loads during<br />
all pumping cycle. Their use<br />
minimizes compression generated<br />
on rods during the<br />
pumping down stroke.<br />
They are manufactured in<br />
compliance with <strong>API</strong> standards<br />
in 11/4" to 2" diameters<br />
in steel per customer request,<br />
with 65,000 psi to 90,000 psi<br />
tensile strength. A proprietary<br />
design alternative, 1 1/8"<br />
pin of 7/8" for 2 7/8" tubing<br />
wells for high rates volume is<br />
available.<br />

Polished <strong>Rods</strong><br />
With an optimal surface<br />
finishing to ensure an<br />
appropriate sealing in the<br />
stuffing box, <strong>Tenaris</strong> offers<br />
several types of low and<br />
medium alloy steel polished<br />
rods (AISI 1040, AISI 4140,<br />
AISI 4621).<br />
For corrosive services,<br />
stainless steel in AISI 304<br />
and 316 series are available<br />
besides steels with hard<br />
chrome plated and Spray<br />
Metal coatings. All these<br />
variations are manufactured<br />
in 6 to 36 feet lengths and<br />
1 1/4" and 1 1/2" diameters,<br />
according to customer’s<br />
specifications.<br />
Polyamide injected centralizer fit for working in up to 80°C.<br />
Its improved geometry reduces flow loss and maximizes protection.
