Product description:

Pipeline pipes and petroleum casing are steel pipes formed by punching through round steel, with no welds on the surface. According to the production method, seamless steel pipes are divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, and hot-expanded seamless steel pipes. Seamless steel pipes are classified into two types based on their cross-sectional shape: circular and special-shaped.

BQO-X100QO Pipeline pipe and Petroleum Casing Tube are high-performance steel pipes developed for high-pressure oil and gas transmission, petroleum drilling, and energy infrastructure under extreme service conditions. Engineered to meet the rigorous requirements of API 5L, API 5CT, ASTM, and ASME standards, these pipes combine exceptional strength, toughness, and corrosion resistance, making them the preferred choice for critical pipeline and petroleum casing applications.

Product Overview

The BQO-X100QO grade is a premium, high-yield-strength steel used in oil and gas transportation pipelines and petroleum well casing systems. It offers exceptional mechanical properties and weldability, allowing safe operation in high-pressure and long-distance pipelines, as well as harsh drilling environments with elevated temperatures, hydrogen sulfide (H₂S), and carbon dioxide (CO₂) exposure.

BQO-X100QO pipes are available in both seamless and welded forms and can be supplied with plain, beveled, or threaded ends depending on project requirements.

Manufacturing Process

BQO-X100QO Pipeline Pipe and Petroleum Casing Tube are produced using cutting-edge processes that guarantee structural integrity, consistency, and performance:

Material Selection: Microalloyed low-carbon steel with Nb, V, Ti, and Mo for fine grain refinement and high toughness.

Forming and Rolling: Thermo-mechanical controlled processing (TMCP) and precision hot rolling ensure strength uniformity.

Heat Treatment: Quenching and tempering optimize microstructure for superior yield and tensile strength.

Inspection: Ultrasonic, magnetic particle, hydrostatic, and impact testing ensure flawless quality.

Surface Protection: Coatings such as black varnish, epoxy paint, or 3LPE/3PP provide long-lasting corrosion resistance.

Every pipe conforms to API 5L PSL2, API 5CT, and ASME B36.10M standards and is delivered with full mill certification.

Key Features

Ultra-high strength (X100 grade) for extreme pressure and long-distance transmission.

Outstanding corrosion resistance against CO₂, H₂S, and seawater environments.

Superior fracture toughness for cold and high-altitude climates.

Excellent weldability for complex on-site installations.

High dimensional accuracy ensures secure joint sealing and low leakage risk.

Custom coatings available for offshore, marine, and desert applications.

Applications:

The application range of seamless steel pipes is very wide, including structures, fluid transportation, low and medium pressure boilers, high-pressure boilers, fertilizer equipment, petroleum cracking, geological drilling, diamond core drilling, petroleum drilling, ships, automotive half shaft sleeves, diesel engines, etc. Seamless steel pipes will be used to avoid leakage and other problems, ensure the effectiveness of use, and improve material utilization. It can be seen that the application of seamless steel pipes mainly reflects three major fields. One is in the field of construction, which can be used for underground pipeline transportation, including extracting groundwater during construction. The second one is in the field of machining, which can be used for mechanical processing, bearing sleeves, etc. The third field is electrical, including gas pipelines and fluid pipelines for hydroelectric power generation.

BQO-X100QO Pipeline Pipe and Petroleum Casing Tube are widely used across the oil, gas, and energy sectors, offering exceptional reliability in:

Oil and gas transmission pipelines: Long-distance transportation under high internal pressure.

Petroleum well casing and tubing: Provides borehole stability and protection in deep and ultra-deep wells.

Offshore oil platforms: Withstands seawater corrosion and pressure cycling.

Cross-country and subsea pipelines: Ensures safety in cold, corrosive, or high-pressure systems.

Refineries and petrochemical plants: Suitable for high-temperature and high-pressure process piping.

These pipes meet the increasing demands of modern energy infrastructure, ensuring efficient, safe, and environmentally reliable operations.
