Partnering with a Leading Thai Energy Company to Deepen Cooperation and Explore the Future – Gnee Steel Successfully Signs Supply Agreement for High-End Inconel 718 Tubing
[December 22, 2025] A delegation led by the Technical Director of a renowned Thai energy equipment manufacturer visited our company for in-depth inspection and technical exchange. Both parties reached a strong consensus on the long-term supply and cooperation regarding Inconel 718 nickel-based alloy tubing and successfully signed an annual procurement framework agreement. This cooperation marks another significant breakthrough for Gnee Steel in its strategic layout in the Southeast Asian high-end special alloy materials market.
During the meeting, both parties focused on discussing the critical applications of Inconel 718 tubing in extreme environments. Due to its high-temperature strength up to 700°C, excellent fatigue resistance, oxidation resistance, and corrosion resistance, this alloy tubing has become a core material in fields such as aerospace engine components, gas turbine discs, deep-well oil and gas extraction (especially in highly corrosive H2S/CO2 environments), nuclear power equipment, and high-performance automotive turbocharger systems. The client explicitly stated that their expansion of deep-sea oil and gas projects and upgrades to gas power generation equipment require almost stringent requirements for the long-term high-temperature creep performance of the tubing, its resistance to stress corrosion cracking in chloride environments, and demanding dimensional accuracy. This was the core reason for their in-depth discussions with our company.
In response to the client's specific operating conditions, our company presented a customized product solution for this cooperation:
Size Range: We can supply a wide range of specifications with outer diameters from Φ6mm to Φ325mm and wall thicknesses from 0.5mm to 30mm, supporting seamless and welded processes, and providing extra-long custom-length tubing to minimize subsequent processing losses for the client.
Core Advantages:
Excellent Strength Stability: Through optimized solution heat treatment + aging heat treatment processes, we ensure that the tubing maintains excellent strength and toughness matching under long-term high-temperature service.
Exceptional Corrosion Resistance: It has strong resistance to various corrosive media such as acids, alkalis, and salts, especially sulfide stress corrosion cracking (SCC) in oil and gas environments, significantly extending equipment maintenance cycles and service life. Precise Dimensions and Process Control: Utilizing advanced cold rolling/cold drawing technology and non-destructive testing (such as eddy current and ultrasonic testing), we ensure that the inner and outer surface finish, wall thickness uniformity, and straightness meet top industry standards, satisfying the demands of precision assembly.
Value-Oriented Pricing Strategy: We adhere to the philosophy of "optimal total cost of ownership." Although Inconel 718 material and processing costs are higher, resulting in a higher initial investment compared to ordinary stainless steel pipes, the resulting increased equipment reliability, significantly reduced maintenance frequency, decreased downtime losses, and significantly extended overall service life will bring customers long-term value far exceeding the initial investment. Our tiered pricing and stable supply chain further ensure the cost controllability and competitiveness of our clients' projects.
Visit and Agreement
Accompanied by Gnee Steel's professional business personnel, the client visited our precision pipe production line, heat treatment workshop, and material testing center. The client highly praised our rigorous process quality control system, advanced testing equipment, and professional technical team.
The client stated: "We chose Gnee Steel not only because of their high-quality, comprehensive range of Inconel 718 pipe products, but also because of their profound technical expertise and customer-centric problem-solving capabilities. This agreement provides reliable material supply for our critical projects, and we look forward to broader cooperation in the future."
Gnee Steel's professional staff responded: "Thank you to our Thai partner for your trust. We will always be committed to providing our customers with the most competitive high-performance nickel-based alloy solutions. This cooperation is not only about signing an order, but also the starting point for technology sharing and mutual value creation. We will ensure stable and timely product supply and full technical support to help our clients maintain their leading position in the high-end manufacturing sector."
This successful cooperation further strengthens Gnee Steel's leading position in the global supply of high-end nickel-based alloy pipes. The company will continue to increase R&D investment to provide higher quality products and services, and work with global partners to meet challenges and create greater value.
