ASTM A312 TP347H Stainless Seamless Pipe Solution Annealing DN50

ASTM A312 TP347H Stainless Seamless Pipe Solution Annealing DN50

Company Introduction

MTSCO was established in 2006. The company has become a leading enterprise in China's comprehensive stainless steel pipe exports. MTSCO is committed to building an integrated one-stop stainless steel complex combining manufacturing and trade. We control the core factory supply chain through investment and deep strategic partnerships, ensuring product quality and stability from source to delivery. All MTSCO products carry international certifications including ISO and PED, ensuring every 347H seamless pipe you receive delivers reliable performance.

Material Properties

347H seamless pipe is a high-chromium, high-nickel austenitic stainless steel. It excels in high-temperature strength and intergranular corrosion resistance. This material is particularly suited for high-temperature environments, resisting carbide precipitation to maintain toughness and corrosion resistance. Consequently, 347H seamless pipe is widely used in critical sectors such as chemical plants, oil and gas platforms, high-temperature/high-pressure systems, and aerospace. MTSCO sources its 347H seamless pipe raw materials exclusively from renowned suppliers like Baosteel and Qingshan, ensuring precise chemical composition and laying the foundation for exceptional high-temperature performance.

Single Process Introduction

Solution annealing is the critical process for optimizing the properties of 347H seamless pipe. This process involves heating the pipe to high temperatures, allowing carbides to fully dissolve into the austenite phase, followed by rapid cooling (quenching). This creates a uniform, supersaturated solid solution. This treatment effectively eliminates cold working stresses, while maximizing corrosion resistance and high-temperature mechanical properties. MTSCO partner factories HUXIN Pipe utilize advanced solution annealing equipment and strict process controls to ensure each 347H seamless pipe possesses a uniform microstructure and stable performance, meeting the most demanding application requirements.

FAQ Of 347H Seamless Pipe

Q1: What is the difference between TP347H and TP347?

A1: The primary distinction lies in carbon content. TP347H features higher carbon content to deliver superior high-temperature creep strength, making it suitable for high-temperature, high-pressure environments (e.g., exceeding 800°F/425°C). MTSCO ensures 347H seamless pipe's chemical composition complies with ASTM A312 standards.

Q2: How do you ensure product integrity during shipping?

A2: We utilize professional industrial packaging. Each pipe is capped at both ends, wrapped in woven bags, and secured within wooden crates to prevent damage during transit.

Q3: Can you supply material compliant with NACE MR0175/ISO 15156 standards?

A3: Yes. For acidic environment applications, we offer specially treated and quality-controlled TP347H steel pipes to meet sulfide stress cracking resistance requirements. Please clearly specify your standard requirements when requesting a quote.
