About Us

LSFB is a Spanish company located in Zaragoza that manufactures and supplies flanged elements; pipes, and Teflon-lined (PTFE/PFA) fittings (and in some cases also on the exterior) for conveying abrasive liquids for the chemical and petrochemical industry.

All our products are internally coated with PTFE (Teflon) tubing that is adhered to the interior walls of the pipes through a lining process.

We have sizes from 1/2” (DN15) up to 16” (DN400) and with different thicknesses from 3 mm up to 12 mm.

We manufacture our fittings according to several standards, mainly ANSI/ASME B16.5 and DIN 2848. We also manufacture according to the measurements required by the client under an approved drawing.

We have various materials available, including carbon steel, stainless steel, and other alloys.

In addition to Teflon-lined pipes, we have other products that you can view in our catalog, which you can download.
