The casing pipe is inserted into the wellbore and cemented to prevent the wellbore from separating the rock formation and wellbore collapsing and to ensure the drilling mud circulation flow. The threaded buckle type of this product includes LTC (Long thread connector), STC (Round threading connector) and BTC (Buttress threading). It is available in R1, R2 and R3 length. Our casing pipe meets API 5CT-2005 standard.
