oil or gas casing pipe

Casing pipes which have smooth wall are used for casing for oil and gas wells. Steel grades and heat treatment regimes applied allow high-strength pipe to be obtained.Corrosion-proofing water-based paint is applied on the outside pipe surface to protect against atmospheric corrosion during transportation and storage. The pipes can be delivered with metal or composite caps at both ends for thread protection.
Pipes produced by Haixing Co. complete its range of specifications:
The outside diameter: 60.3mm,73mm,139.7mm,177.8mm,244.5mm,etc.
The thickness: 7.72mm,9.19mm,8.94mm,10.03mm,etc.
The length: R-1,R-2,R-3.

The wire and rod, generally made from carbon or stainless steel, are joined by resistance welding; screen sections usually are 20 feet long. Continuous slot screens are suitable for wells in relatively shallow, thin aquifers that are very prolific in terms of water production. These screens are engineered with a very small slot size, yet are designed to maintain the necessary open area to minimize frictional head loss.

Advantages:

1.Wide range of slot sizes available.

2.High amount of open area, making good development possible and therefore, best possible samples can be obtained.

3.Made in both telescoping and pipe sizes.

4.Most efficient available screen.

5.Slot sizes can be custom made to aquifer gradations.
