High Durability Stainless Steel Pipe 21mm Diameter 5m Length Stainless Steel Seamless Pipe

Industrial Seamless Steel Pipe Product Description

Our industrial seamless steel pipes are engineered to meet the rigorous demands of diverse industrial sectors, integrating premium materials, precision manufacturing, and customizable solutions. Covering three core material categories—carbon steel, stainless steel, and alloy steel—each pipe undergoes strict quality control to ensure consistent performance in high-pressure, high-temperature, and corrosive environments. What sets us apart is the integration of on-demand processing services, including threading, cutting, drilling, and polishing, which eliminates the need for on-site secondary processing and significantly improves project efficiency. Whether for oil & gas transmission, building structural support, or municipal water supply, our seamless pipes deliver reliability and durability that align with global industrial standards.

Specification Range & Technical Parameters

We offer a comprehensive range of specifications to match varied application scenarios, with flexible customization options for non-standard requirements. The detailed technical parameters are as follows:

Product Details & Core Advantages

1. Seamless Manufacturing Process: Our pipes are produced via hot rolling and cold drawing processes, eliminating weld seams that are prone to cracking or leakage. This seamless structure ensures uniform stress distribution, making them ideal for high-pressure applications like oil & gas pipelines and hydraulic systems.

2. Material-Specific Performance: Carbon steel pipes (e.g., Q235, 10#) offer high strength and cost-effectiveness, suitable for general industrial and construction scenarios; stainless steel pipes (304, 316) feature excellent corrosion resistance, perfect for chemical processing and marine environments; alloy steel pipes (4130) excel in high-temperature resistance (up to 600°C), making them suitable for power generation and aerospace auxiliary equipment.

3. Precision Surface & Processing: Surface treatments like galvanization and black oxide enhance corrosion resistance, extending service life by 30% compared to untreated pipes. Custom processing services are executed with advanced CNC equipment—threading ensures tight connections with no leakage, cutting guarantees accurate lengths for quick installation, and drilling supports specialized mounting needs (e.g., sensor installation in industrial pipelines).

Application Scenarios

Our seamless steel pipes are widely used across key industrial sectors, with material and specification options tailored to each field’s unique requirements:

• Oil & Gas Industry: Carbon steel and alloy steel pipes (15mm-30mm diameter, 6m-12m length) are used for crude oil and natural gas transmission. The seamless structure resists underground corrosion and high-pressure impacts, while galvanized surface treatment prevents rust in offshore drilling environments.

• Construction Sector: Thick-wall carbon steel pipes (20mm-30mm wall thickness) serve as structural supports for high-rise buildings and bridges, leveraging high strength to bear heavy loads; stainless steel pipes are used for decorative and load-bearing components in modern architecture due to their aesthetic appeal and corrosion resistance.

• Water Supply & Municipal Engineering: Galvanized carbon steel pipes (10mm-25mm diameter) are applied in municipal water supply networks, as the zinc coating prevents rust from contaminating water quality. Thin-wall stainless steel pipes are used in residential water supply systems for their hygiene and long service life.

• Industrial Equipment: Thin-wall seamless pipes (6mm-12mm diameter) are used in heat exchangers and hydraulic systems, where their smooth inner surface reduces fluid resistance; alloy steel pipes are integrated into power plant boilers and chemical reactors, withstanding high temperatures and corrosive media.

About Our Factory

With over 15 years of experience in seamless steel pipe production, our factory is equipped with a complete production line—from raw material testing to finished product inspection. We hold ISO 9001 quality management system certification and use high-quality raw materials from renowned steel mills (e.g., Baosteel, POSCO) to ensure product consistency. Our production capacity reaches 5,000 tons per month, enabling timely delivery for both small-batch custom orders and large-scale bulk purchases.
