 Sucker
Rod Submit Energy
1.
API standard steel sucker rod;
Design to be used with moderate to heavy loads in
non-corrosive or effectively inhibited wells. Our
Sucker Rod is complying with API SPEC 11B
Specification to manufacture. From the process of
defect detection, selection of high quality of alloy
steel and then process to straightening, forging, fault
detection, quenching, flash back, impeller blasting,
assembly, packing, painting, the final product then will
be stored in the warehouse. Using fluorescent
magnetic fault detection and imported Eddy
current inspection instrument to inspect sucker rod head
and the rod body, the quality of the product is being
assured.
The performance of the
D
Alloy Grade Sucker
Rod is excellent, price competitive,
safe, and lower the oil extraction cost significantly.
Another material of Grade D Sucker Rod: Carbon Steel is
also available from us based on customer’s special
request.
2. API Polished Rod:
Alloy Steel
Design to be used with moderate to heavy loads in
non-corrosive or effectively inhibited wells. The
polish rod is using (AISI 4130) Mod steel to
manufacture.

3. Pony rod;
The pony rods chemical properties, rod diameters,
dimensions and tolerance are same as sucker rods.
Standard lengths: 2ft (0.61m), 4ft (1.22m), 6ft (1.83m)
,8ft(2.44m) ,and 10ft(3.05m).Other
lengths are available on special order.
4. Coupling;
Two types of coupling are available: Class T and Class
SM, full size and slim size. Dimensions and tolerance
conform to API spec. 11 B. Couplings are available in a
variety of styles in most sucker rod sizes and
combination of sizes.
The minimum tensile strength of the coupling is 95,000
psi (655MPa) and the material hardness is 56 to 62 HRA.
5. Sub-coupling;
5/8”-3/4” T(SM), 3/4”-7/8”T(SM), 7/8”-1”T(SM), 1”-1 1/8”
T(SM).
6. Sinker bar;
The sinker bar
offered two grades to customers: grade 1 (carbon) and 2
(alloy) and the
available sizes are
1 1/4”, 1 1/2”, 1 3/8”, 1 5/8”, 1 3/4”.
Advantageous of using sinker bar:
Create constant tension in the rod string when the
sinker bar placed at bottom of the rod string.
Eliminates compression on the rod string ,reduce the
amount of fatigue failures and the chances of buckling;.
Reduction in rod and tubing wear if including sinker bar
in the rod string. |
