Standard Glass unveils world’s First Glass-Lined Heat Exchangers In India

Hyderabad: Standard Glass Lining Technology Limited (SGLTL), a Hyderabad-based engineering company recently listed on NSE and BSE, has announced a groundbreaking partnership with Japan’s AGI Group and its affiliate GL HAKKO to manufacture the world’s first glass-lined shell and tube heat exchangers in India.Under the terms of a 20-year exclusive licensing agreement, SGLTL will assemble and market GL HAKKO’s advanced heat exchangers domestically—a major technological leap for India's pharmaceutical and chemical manufacturing sectors. This collaboration marks India’s entry into a highly specialized product segment that, until now, was completely dependent on imports.

“This is a historic opportunity,” said Nageswara Rao Kandula, Managing Director of SGLTL. “Partnering with AGI and GL HAKKO—pioneers in glass-lined technology—is not just a milestone for our company, but a win for the entire Indian industry. We are now the first and only manufacturer of this product in India.” The global market for glass-lined shell and tube heat exchangers is estimated at over $2 billion, with the Indian market pegged at Rs2,000 crore. These exchangers offer significant advantages over traditional graphite-based systems, including enhanced corrosion resistance, longer life cycles, and improved safety for critical process applications.

SGLTL has already received 150 advance orders and is gearing up to begin domestic production by Q4 FY26 at its upcoming high-tech facility with an estimated monthly capacity of 200 units. In a parallel development, SGLTL has also signed a separate exclusive agreement with GL HAKKO to manufacture Conductivity Glass-Lined Reactors—a first in India. These reactors are engineered to instantly discharge static electricity, mitigating a common safety hazard in chemical and pharmaceutical plants.
