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.

BNO-X52NO Pipeline pipe and Petroleum Casing Tube are high-quality steel pipes designed for oil and gas transportation, petroleum extraction, and pipeline infrastructure in demanding industrial environments. Manufactured in accordance with API 5L, API 5CT, ASTM, and ASME standards, these pipes provide exceptional mechanical strength, corrosion resistance, and long-term reliability for both onshore and offshore applications.

Product Overview

The BNO-X52NO grade is a specialized pipeline and casing steel that ensures safe, efficient, and stable performance under high internal pressure and extreme environmental conditions. It is commonly used for oil and natural gas transmission pipelines as well as petroleum well casing tubes that stabilize boreholes and prevent collapse during drilling operations.

Available in seamless and welded forms, BNO-X52NO pipes come in plain, beveled, or threaded ends to meet various installation and connection requirements.

Manufacturing Process

BNO-X52NO Pipeline Pipe and Petroleum Casing Tube are produced under strict quality control and advanced metallurgical technology to guarantee performance consistency:

Material Selection: Fine-grain low-carbon steel alloyed with manganese, niobium, and vanadium for enhanced strength and weldability.

Forming Process: Hot rolling, controlled rolling, or seamless extrusion to ensure a uniform and dense structure.

Heat Treatment: Normalizing, quenching, and tempering processes improve toughness and impact strength.

Testing and Inspection: 100% ultrasonic, hydrostatic, and magnetic particle tests ensure no internal or surface defects.

Surface Protection: Black varnish, 3LPE coating, epoxy painting, or galvanization to protect against rust and corrosion.

All manufacturing complies with API 5L PSL1/PSL2, API 5CT, and ASME B36.10M standards.

Key Features

High strength and pressure resistance for long-distance oil and gas pipelines.

Excellent corrosion resistance against H₂S, CO₂, and chloride environments.

Superior weldability and formability, ideal for field installation and bending operations.

Excellent low-temperature impact toughness, ensuring safety in arctic and offshore regions.

Precision dimensional control for leak-free and secure connections.

Versatile coating options to extend service life in harsh environments.

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.

BNO-X52NO Pipeline Pipe and Petroleum Casing Tube are essential materials in global energy and petrochemical sectors, widely used for:

Oil and gas transmission pipelines: Transporting crude oil, natural gas, and refined fuels.

Petroleum drilling and casing: Providing borehole protection and structural support.

Offshore and onshore pipeline projects: Resistant to corrosion and pressure fatigue.

Refineries and petrochemical plants: Used in process piping and pressure systems.

Underground and subsea pipelines: Excellent durability under corrosive and high-stress environments.

Its reliability, mechanical stability, and corrosion resistance make BNO-X52NO a preferred choice for pipeline contractors and petroleum engineering companies worldwide.
