Oil Country Tubular Goods (OCTG) refer to collections of rolled metal products or pipes and the accessories that are included in their manufacturing and processes.

With competitive price and timely delivery, BH sincerely hope to be your supplier and partner.

OCTG Products

These items include, but are not limited to, thread protectors, stabbing guides, pipe chocks, and bumper rings, along with drill, casing, and tubing pipes &#; the most critical element of OCTG. Pipe products are considered OCTG because of the specifications of each pipe with concerns to acceptable loading conditions, what they are capable of transferring, and their strength and composition.

Drill pipes are heavy duty, strong and critical in any OCTG endeavor. The heavy, often seamless tubes are used in the rotation of the drill bit and drilling fluid where they can be joined using tool joints. When in use, pipes undergo axial tension along with high torque and internal pressure from the pipe&#;s own dead weight when in use, exhaust of drilling fluid, and the actual drilling and turning of the bit.

A different type of pipe used to line the borehole (the actual hole dug in the ground) is referred to as a &#;casing pipe&#;. It too, undergoes axial tension just like the drill pipe, but it differs in that it has to withstand addition pressure from the rock and sediment that it has bored into, along with pressure from the oil itself. It is also extremely heavy duty.

An additional pipe will go inside the casing pipe and will eventually become the pipe through which the oil will travel. This pipe is referred to as a &#;tubing pipe.&#; Tubing pipes are usually produced in segments of about nine meters (or approximately 30 feet), with threaded connectors at each end. Tubing pipes are the most simplistic of the OCTG pipe family. The connectors at the end of tubing pipes can and should be protected by drill pipe protectors during storage and transportation. This will also protect against corrosion that can happen. When tons of oil are being pumped through tubing pipes, it is imperative that there are no damages that could compromise the integrity of the pipe threading.

Oil Country Tubular Goods (OCTG) is a type of steel pipe used to transport crude oil, natural gas and other fluids in the oil and gas industry. It consists of metal attachments and steel pipes, which come in different sizes and grades, and each length of pipe has a special function and purpose. The purpose of the OCTG connection is to connect these steel pipelines together in series to build a network that can transport oil and gas from one location to another.

API Connection
API connection is a type of connection widely used in the oil and gas industry. They meet and exceed all of the American Petroleum Institute&#;s (API) regulatory standards. The API defines two types of coupling: one is undisturbed coupling (NU) and the other is externally disturbed coupling (EU). The NU connection is designed to connect two pipes of the same diameter, while the EU connection is designed to connect two pipes of different diameters.

Advanced connectivity
Advanced connectivity is a special type of proprietary connection that provides advanced features that API connectivity does not. Most advanced connections offer metal-to-metal seals to improve the integrity of high-pressure seals. The advanced connection has the characteristics of straight connection, no slot and special gap. This connection is suitable for gas Wells, high-pressure Wells, and Wells prone to corrosive wastewater production.

Furthermore, OCTG threading technology is a process method for forming grooves in the casing body and end. 

It can form a seal with these grooves when the pipe is connected to another device or pipe. Threads are generally leak-proof and robust enough to withstand oil and gas distribution grids. There are three different types of OCTG casing, each with its own unique advantages: for example, short round thread casing (STC), long Round thread casing (LTC), and support thread casing (BTC).

STC is considered the preferred solution for short length casing applications that do not involve high axial loads or bending. LTC is particularly suitable for axial loads, except in the case of extreme temperature or pressure overall well conditions. BTC is an excellent connection that provides long life in the face of high axial loads, moderate internal pressures and temperatures. Both the STC and LTC are round threads of a non-runout design with 8 dome threads per inch. The BTC has a flat root and flat top square thread, a runout design, and is equipped with five support threads per inch.

Each type of OCTG thread has different advantages and performance, which also makes OCTG the best choice for some applications. When choosing the best type of threading for your project, be sure to consider the well condition and the type of equipment that will be used.
