20CrMnTi and 20CrMnTiH seamless steel pipes for gears, shafts and mechanical components. Custom sizes, testing and MTC available.
The core difference between GI (Galvanized Iron / Steel) outer-protected insulation pipes and HDPE (High-Density Polyethylene) outer-protected insulation pipes lies in the material of the outer protection, applicable scenarios, and construction methods. GI is more suitable for overhead/exposed installation, while HDPE is more suitable for direct burial.
Yunnan Youfa Fangyuan successfully produces its first hot-dip galvanized square tube, enhancing high-quality steel pipe supply in Southwest China. Ideal for building, municipal, and telecom projects.
Seamless steel pipes are essential materials in industrial manufacturing and construction projects. Known for their high strength, pressure resistance, and corrosion resistance, they are widely used in the oil and gas, mining, machinery, and construction industries. Understanding the weight per meter of seamless steel pipes is critical for project planning, transportation, and cost management.
Seamless steel pipes, as critical industrial materials, are widely used in fields such as petroleum, chemical industry, electric power, and mechanical manufacturing. Their quality directly impacts the safety and reliability of entire projects. However, throughout the lengthy production process from raw materials to finished products, negligence at any stage can lead to quality defects. This article will systematically elaborate on how to establish multi-layered quality defense lines to ensure seamless steel pipes meet standard requirements.
Packaging plays a vital role in the production and delivery of seamless steel pipes. As these pipes are widely used in oil & gas, mining, construction, and heavy industry, they often undergo long-distance transportation and multiple handling processes before reaching the end user. Proper packaging is therefore essential.
Starting in 2026, China will implement export license management for some steel products, aiming to guide the industry towards high-end and green transformation, ensure supply chain stability, and optimize the structure of foreign trade.
Chinese companies have successfully developed and delivered super duplex steel seamless coiled pipes with a single length exceeding 4,000 meters, breaking the long-standing foreign monopoly in this field and marking that my country has reached the international advanced level in the field of ultra-long high-end special pipes.
Brazil will initiate an anti-dumping investigation in November 2025 on certain sizes of seamless carbon steel pipes originating from Malaysia, India, and Thailand, at the request of domestic companies.
Tianjin Pipe has successfully overcome the technical bottleneck of the difficulty in achieving both ultra-high strength and high toughness, and has developed and trial-produced the TP165D high-strength and high-toughness drill pipe, which strongly supports the strategic demand for deep oil and gas resource exploration in China.
