Pulp & Paper

Alleima has a long history of pioneering materials designed to perform in extreme environments. Since the 1970s, the company has been at the forefront of composite tube research and development, delivering reliable solutions for BLRBs globally. Our hot-extruded and cold-pilgered composite tubes ensure a strong metallurgical bond, smooth surfaces, and long-term durability, offering superior reliability over welded alternatives.

Global standards, locally delivered

Every tube produced at the Alleima Zhenjiang tube mill meets the same rigorous quality standards as our flagship facility in Sandviken, Sweden, ensuring trusted performance wherever you operate.

We deliver consistent quality, reliability, and full traceability through a fully integrated value chain, from R&D and melting to final testing. The Phase II expansion enhances our ability to support customers locally across China and rest of Asia with shorter lead times and closer collaboration.

Alleima invests in new facility in China to meet increasing demand in the Chemical and Petrochemical segment

Alleima is increasing its capacity for application tubing products, such as heat exchanger tubes, through an investment of approximately SEK 250 million in a new cold-finishing facility in Zhenjiang, China.

Proven solutions for the Pulp and Paper industry

Few assets are as critical to a pulp mill as the recovery boiler, and few face harsher operating conditions. If it fails, everything stops. Black liquor recovery boilers (BLRBs) play a critical role in the pulp and paper process by recovering chemicals and generating energy, and they also operate in some of the harshest conditions in the industry.

Alleima's Commitment to APAC's Hydrogen Future

The race towards a cleaner and more sustainable future demands innovative solutions to address the challenges of our current energy landscape. With global electricity consumption growing at record rates, and the need to reduce greenhouse gas emissions and achieve ambitious decarbonization goals, one promising solution rapidly gaining traction is hydrogen.

Materials that push the possibilities for industries in China & the rest of Asia

From large and complex assets in the hydrogen, pulp and paper, and chemical and petrochemical industries to the high precision demands of the medical device market, operators face several significant challenges, often daily. But what are sometimes regarded as the smaller details matter, too.
