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.

BQ-X80Q Pipeline pipe and Petroleum Casing Tube represent a new generation of high-strength, high-toughness steel pipes engineered for the oil, gas, and energy transmission industry. Manufactured under API 5L, API 5CT, and ASME standards, these pipes are designed to perform reliably under high pressure, long-distance, and extreme environmental conditions.

Product Overview

The BQ-X80Q grade is an advanced high-strength pipeline steel with enhanced yield strength and impact resistance. It is widely used in oil and natural gas transmission pipelines, petroleum casing and tubing, and deep well drilling operations.

This steel grade provides superior resistance to hydrogen sulfide (H₂S) and carbon dioxide (CO₂) corrosion, ensuring long-term reliability in sour service and high-pressure environments. Available in both seamless and welded forms, BQ-X80Q pipes can be supplied in plain end, beveled, or threaded types according to project requirements.

Manufacturing Process

Each BQ-X80Q Pipeline Pipe and Petroleum Casing Tube is produced using advanced metallurgical and inspection processes to ensure exceptional consistency and performance:

Material selection: Microalloyed carbon-manganese steel with niobium (Nb), vanadium (V), and titanium (Ti) for refined grain structure.

Forming and rolling: Hot rolling or seamless extrusion to achieve superior strength and uniformity.

Heat treatment: Quenching and tempering for optimized strength, ductility, and low-temperature toughness.

Testing and inspection: Ultrasonic, magnetic particle, hydrostatic, and impact tests performed on every batch.

Surface protection: Black varnish, epoxy, 3LPE/3PP, or galvanized coatings for corrosion control.

All products comply with API 5L PSL2, API 5CT, and ASME B36.10M specifications, ensuring consistent quality and reliability.

Key Features

Ultra-high strength: Excellent yield and tensile properties for long-distance, high-pressure pipeline systems.

Exceptional corrosion resistance: Withstands sour gas and marine environments.

Superior toughness: Maintains impact strength even at sub-zero temperatures.

Excellent weldability: Suitable for complex field installations and automatic welding.

Stable dimensional accuracy: Ensures leak-free joints and consistent wall thickness.

Multiple coatings available: Provides extended life under corrosive conditions.

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.

BQ-X80Q Pipeline Pipe and Petroleum Casing Tube are widely used in the energy and petrochemical industries, providing reliable performance in diverse and challenging conditions:

Oil and gas transportation pipelines: Efficiently transports crude oil, natural gas, and refined fuels.

Petroleum casing and tubing: Ensures wellbore stability and prevents fluid contamination during drilling.

Offshore exploration: Provides strength and corrosion resistance under seawater exposure.

High-pressure transmission systems: Suitable for cross-border and long-distance energy pipelines.

Refineries and petrochemical facilities: Used in high-temperature and high-pressure piping systems.

The superior mechanical stability and corrosion resistance of BQ-X80Q make it ideal for use in deserts, marine platforms, frozen tundra, and deepwater oilfields.
