Casing pipe
 

 

 

A casing pipe is a hollow steel tube that is typically rammed into place through the earth by using a hydraulic or pneumatic jack. After being driven, the displaced soil is removed and the product pipe, or carrier pipe, is inserted inside the steel tube.

Packing
 

There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.Our packing can meet any needs of the customers.


Hollow Steel Tube Casing Pipe 20 Inch Oil API For Oil Wells 4

 


Plastic caps plugged at the two sides of pipe ends
Should be avoided by the steel strapping and transport damage
Bundled signs should be uniform and consistent
The same bundle(batch) of steel pipe should be came from the same furnace.
The steel pipe has the same furnace number, the same steel grade, the same specifications.
