OCTG is the abbreviation of Oil Country Tubular Goods, it mainly refers to the piping products that applied in the oil and gas production (drilling activities). OCTG pipe normally is manufactured based on API or related standard specifications. It also could be taken as a collective name of Drill pipe, Steel Casing Pipe and Tubing pipe, Couplings, Connections and Accessories, used in petroleum industries that onshore and offshore. According to the API (American Petroleum Institute) standardized specifications, through the control on the chemical properties and adopts different heat treatment, OCTG pipe is classified into different performances material more than ten […]

Heavy Weight Drill Pipe (HWDP) Our Heavy Weight Drill Pipe (HWDP) offers a gradual transition from heavy, rigid drill collars to the more flexible drill pipe which helps to reduce the number of fatigue failures seen directly above the Bottom Hole Assembly (BHA). We offer heavy weight in 3.1/2″, 4″, 5″ and 5.1/2″ consisting of hard banded tool joints and raised wear pads on central upsets to optimize wear resistance. We offer two types of HWDP configurations; Standard HWDP and Spiral HWDP. Standard HWDP Prevents stress concentration and allows directional drilling with controlled torque and reduces differential pressure sticking. Spiral HWDP Designed to handle maximum stresses induced at harsh drilling environments in vertical and directional wells. Shares many of the same features from the Standard HWDP. Better reduction in differential sticking Increased weight and stiffness Minimizes wear Improves cutting circulation for better hole cleaning Our preferred applications of hard banding for drill pipe tool joints and BHA components (HWDP, Drill Collars) are ARNCO 350XT or Duraband NC, both NS-1 certified; which are not only designed to protect the drill pipe from wearing but also to protect the casing. We use a robotic welding system for hardbanding drill pipe. HWDP – 3.500 – NC38 HWDP – 4.000 – MT39 HWDP – 4.000 – XT39 HWDP – 5.000 – NC50 HWDP – 5.500 – HT55 HWDP – 5.500 OD x 3.250 ID – DPMDS55 HWDP – 5.500 OD x 4.000 ID – DPMDS55

Black steel pipe is used in applications that do not require the pipe to be galvanized. This non galvanized black steel pipe acquired its name because of its dark coloured iron oxide coating on its surface. Because of the strength of black steel pipe , it is used for transporting gas and water to rural areas and for conduits that protect electrical wiring and deliver high pressure steam and air. The oil field industry also uses black pipes for piping large quantities of oil through remote areas. erw black carbon iron schedule 40 steel pipe Product Name: astm a53 […]

In recent years, with the decreasing number of easily exploitable oil and gas wells, it has become necessary for oil and gas wells to go deeper on both underground and underwater. And, tubing and casing strings are subjected to higher temperature and higher pressure in these wells, which would probably cause casing failure or gas leakage in the high-pressure/high-temperature (HPHT) wells. Hence, more attention has been paid to wellbore integrity in oil and gas industry in recent years.1,2 The key factor of wellbore integrity is casing string connections, which are expected to provide both structural and leakage integrity under severe environment.

Methods for preparation and construction of protective coatings for petroleum pipelines [57] Abstract The invention provides a protective coating for oil pipes and wellheads and downhole equipment used in oil and gas drilling, oil recovery and transportation. The protective coating comprises, by weight percentage, 55 to 95% of polyphenylene sulfide, 3 to 30% of adhesion enhancer, and 1 to 20% of abrasion resistant enhancer. A surface wettability converting agent may also be included in the range of 1 to 15%. It can prevent or reduce the high temperature, high pressure, high hydrogen sulfide and carbon dioxide, high salt content and other strong corrosive […]

Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts through the rock formations and allows drilling engineers to reach the reservoir below, the raw sides of the well cannot support themselves. Similar to the bones of your spine protecting the spinal cord, casing is tubing that is set inside the drilled well to protect and support the ABTER STEEL. You can choose the oil casing to use, select the casing size range as follows： Standard: API 5CT Steel Grade: J55, K55, N80, L80, C90, T95, P110, Q125, V150 Dimension: 4 1/2″–20″ Connection: BTC, STC, LTC * P – […]
