solutions, announced today that a set of large-scale customized shell-and-tube heat exchangers has been successfully manufactured, tested, and officially shipped to Kazakhstan.
This equipment will be applied to the core process upgrading project of a large petrochemical enterprise in Kazakhstan, serving as a key energy-saving device in its refining and chemical integration unit. This delivery not only marks the high recognition of GNEE's products in the markets along the "Belt and Road" but also demonstrates its outstanding strength in the international high-end manufacturing field.
The delivered heat exchanger is a BES type floating-head heat exchanger, designed and manufactured in strict compliance with ASME and TEMA standards.
: Shell side 4.0 MPa / 250℃, Tube side 2.5 MPa / 200℃.
: Up to 1,850 square meters, employing efficient low-finned tube enhanced heat transfer technology.
: The tube bundle is made of corrosion-resistant SA-213 TP316L stainless steel, and the shell is SA-516 Gr.70 hydrogen-resistant steel to withstand complex process media.
: To address the problem of fouling prevalent in the customer's process, GNEE's engineering team innovatively adopted a "variable-pitch spiral baffle" design. Compared with traditional single-segmental baffles, this design not only effectively reduces the shell-side pressure drop by approximately 30% but also significantly reduces fouling deposition and flow dead zones by creating a spiral flow path. It is expected to extend the customer's cleaning cycle by at least 50%.
During the contract execution period, the Kazakhstan customer dispatched an expert team consisting of the Chief Process Engineer and the Quality Director to conduct a three-day key node audit at GNEE's production base. The customer team went deep into the workshop to witness the entire process from raw material cutting, tube sheet drilling, bundle assembly, to hydraulic expansion and final welding. They highly praised GNEE's strictly implemented "12 quality control checkpoints" (from incoming material inspection to final pressure testing). At the technical exchange meeting, both engineering teams conducted simulation deduction on the extreme working conditions the installation might face in the future. Based on this, the GNEE team strengthened the design of the local support structure. This in-depth interaction, customer-centric and operational-oriented, has won the full trust of the customer.
: Design, procurement, and production preparation proceed simultaneously, with key long-lead items locked in advance.
: The workshop operates 24 hours in two shifts. Critical path processes are handled by the most experienced technician teams to ensure first-pass quality and eliminate rework.
: Considering the winter road conditions on the Central Asian route, GNEE's logistics team formulated a detailed transportation plan. Special rain and snow-proof, shock-proof packaging frames were designed for the equipment, and a real-time GPS temperature and vibration monitoring system was equipped to ensure absolute reliability.
Faced with complex processes, stringent international standards, and tight schedules, are you also looking for a reliable partner? With over 18 years of design and manufacturing experience in the field of shell-and-tube heat exchangers, GNEE has successfully provided reliable and efficient heat exchange solutions to customers in more than 50 countries and regions worldwide.
