    1. Casing Pipe
    2. Casing PipeDuring oil extraction, different types of well casings are used. The purpose of surface casing, for example, is to protect fresh water zone and shallow gas zone from oil or gas contamination. Another noteworthy device is the casing hanger, which is installed in the well head and hangs the casing.
    1. OCTG Pup Joint
    2. OCTG Pup JointAccording to the way the joint is connected to the casing string. The threaded version is further classified into two types. One comes with male threads at both ends, and the other type comes with male and female threads at each end, respectively. According to the usage, the joint also can be divided into two categories, production tubing joint and pipe casing joint.
    1. OCTG Couplings for Casing & Tubing
    2. OCTG Couplings for Casing & TubingThe OCTG coupling is a short length of pipe used to connect two joints of casings or production tubings. Unlike ordinary couplings, it effectively solves the problem of fatigue fracture that is easily caused by the stress concentration. The coupling is normally made of the same grade of steel as the casing or tubing.
    1. API Thread Protectors
    2. API Thread ProtectorsAs an indispensable item generally used in combination with other oil country tubular products, the thread protector serves to ward off the impact during pipe loading and unloading as well as any potential damage during pipe transportation. The polyethylene used for protector-making serves as the aggregate, which combines with the steel matrix ...
    1. Hot-rolled Seamless Pipe
    2. Hot-rolled Seamless PipeDuring the manufacturing process, the undesired microstructure of the ingot can be broken down and the grains in that structure can be re-arranged and refined to eliminate any structural defects. The result is that our steel product has enhanced mechanical properties and granularity.
    1. ASTM Seamless Pipes
    2. ASTM Seamless PipesUtilizing seamless pipes to make circular parts minimizes the use of raw material, simplifies the manufacturing process and saves manufacturing time. Typical examples of circular parts are the outer and inner rings of rolling bearing as well as the jack bushing. In addition, the pipe is an indispensable item in making conventional weapons including guns and artilleries.
    1. Square Hollow Sections
    2. Square Hollow SectionsSometimes also referred to as box section, our square hollow section exhibits the same flexural strength and tensile strength as the solid round tube while having lighter weight than the latter. Durable and dependable, the box section does have a temptation, due also to the cheap price. Plenty of applications exist for the box section.
