The Codeline history is rich with industry firsts that set the standard for quality and reliability. We were the first to introduce ASME Section X certified FRP membrane housings, and the first to offer NSF61 product certifications for membrane housings.
In the 1980s, Advanced Structures produced 4 inch and 8 inch diameter FRP membrane housings as the  series U4 and U8. Advanced Structures introduced the 4B series along with the E8 and E8/SP series in 1986. Both models have long been the benchmark in the industry.
Our company name was changed to Codeline in 1999 when, as part of the Essef acquisition that also added structural pressure vessels to our product line, we became a Pentair company.

Pentair Codeline accelerated the pace of innovation and introduced the 80R and 80A series. In 2009, Pentair Water India became the global supplier for Codeline membrane housings, allowing us to centralize production and introduce the Codeline 80S, 80H and 80U series. All products are manufactured in accordance with the Pentair integrated management system, using advanced manufacturing technology in ISO-certified facilities.
