Specifications Of Alloy 800H Seamless Pipe

How Do We Ensure Perfect Delivery of 800H Pipes?

MTSCO's 800H seamless pipes utilize an integrated packaging solution featuring multi-layer professional protection, balancing comprehensive safeguarding with efficient transportation. Each pipe is fitted with end caps at both ends to shield the pipe ends from impact during transit. Outer packaging utilizes woven bags or wooden cases according to shipping requirements. This ensures the high-value 800H alloy pipes remain in optimal protective condition throughout the entire journey from factory to site.

Customer Case Studies

MTSCO's high-performance products have successfully participated in numerous international high-end projects, demonstrating their reliability in extreme environments. We supplied critical pipe fittings and flanges for the FPSO P80/P83 and P78 projects, provided welded pipes and fittings for Intel's precision manufacturing facilities, and delivered high-quality seamless pipes for the KUG project. Additionally, we serve as a stable supplier to global top-tier oilfield service companies HALLIBURTON and WEATHERFORD, meeting their stringent requirements for material quality and supply chain stability. Our consistent service to these international projects with “zero tolerance” for quality issues validates the exceptional performance and reliability of MTSCO products. The quality inspection standards we implement for alloy 800H seamless pipe align with those of these top-tier projects, ensuring every meter of pipe you receive is delivered with zero defects.

Where Does Alloy 800H Pipe Excel in Extreme Environments?

Alloy 800H seamless pipe is the material of choice for extreme conditions due to its exceptional high-temperature resistance and creep resistance. It is extensively used in critical equipment systems requiring long-term operation under high-temperature and high-pressure conditions, providing reliable safety assurance for industries such as energy, chemical processing, and petroleum refining.

Typical applications include:

• Radiant section furnace pipes and reformer pipes for ethylene cracking furnaces

• Steam superheater and heat exchanger piping systems

• Heat exchange components for nuclear power systems

• Carburizing furnace vessels for heat treatment equipment

FAQ About Nickel Alloy 800H Pipe

Q1: What is the difference between alloy 800H and 800HT?

A1: Both have similar compositions, with key distinctions in titanium, aluminum, and carbon content, plus minimum creep strength requirements. Alloy 800HT features higher titanium and aluminum levels and must meet the creep rupture strength specifications outlined in ASTM B408, making it suitable for more demanding high-temperature, high-pressure applications. MTSCO can assist you in selecting the most appropriate grade for your specific operating conditions.

Q2: What lengths of alloy 800H seamless pipe can you supply?

A2: We offer a wide range of dimensions. Beyond standard lengths, our advanced equipment at the holding factory enables us to provide extended lengths up to 25 meters. This helps reduce weld points in your projects and enhances overall system reliability.

Q3: Is this material suitable for acidic environments?

A3: Alloy 800H excels in high-temperature strength and oxidation/carburization resistance. While offering some corrosion resistance, its pitting resistance in strongly acidic environments (e.g., chloride-containing) is inferior to duplex stainless steels or nickel-based alloys like Hastelloy.
