Line Pipe

Line pipes are mainly used for the transportation of gas, water, oil and other media in petroleum, natural gas, chemical, electric power and other industries. The line pipe products independently researched and developed by GS have now formed the manufacturing capabilities of multi-purpose and high-end products such as PSL1 line pipe, PSL2 line pipe, subsea line pipe, acid line pipe, and cryogenic line pipe, which can meet the different needs of customers. The highest strength level can reach X100Q/L690Q, the outer diameter range of the steel pipe: 60.3～762mm, and the wall thickness range: 3.5mm～120mm. The quality of GS steel line pipe products is stable and widely used in many key engineering projects at home and abroad.
End type: bevel end/ plain end.

Tubing and Casing for Special Service(13 chrome)

Tubing and Casing for Special Service(13 chrome)

For oil and gas reservoirs with high sulfur content that are likely to cause casing corrosion and cracking, GS has independently developed 80S/SS～110S/SS grades of oil well pipes with hydrogen sulfide stress corrosion resistance series, which have excellent mechanical properties and resistance to hydrogen sulfide stress corrosion cracking. Other grades mainly include 1%chrome, 3%chrome, 9% chrome, 13 chrome, super 13, etc.
 

Premium Connection for Casing and Tubing

Premium Connection for Casing and Tubing

Tubing main seal is a 30o angle taper metal to metal seal, which can provide excellent gas tightness even after repeated make-ups breakouts. The design virtually eliminates all risk of seal galling. Casing main seal is a low taper seal (10% taper on diameter) providing gas tightness under high-tension loads such as with heavy string weights.

API SPEC 5CT Oil Tubing

API SPEC 5CT Oil Tubing

Whole series of API SPEC 5CT oil tubing indicate the steel pipes produced as per API 5CT specification, used for exploiting resources such as petroleum and natural gas,etc. Oil tubing is used to extract oil and natural gas, casing is used as wall of oil and gas well bore.

API SPEC 5CT Casing Pipe

API SPEC 5CT Casing Pipe

Whole series of API SPEC 5CT casing pipe indicate the steel pipes produced as per API 5CT specification, used for exploiting resources such as petroleum and natural gas,etc. Tubing is used to extract oil and natural gas, casing is used as wall of oil and gas well bore.
Steel Grades : J55,L80,P110,Q125,V150
