BAUM America CorpBaum Kunststoffe GmbH, a German company founded by Roland Baum in 1986, is a worldwide leader in the plastic lined piping industry. They manufacture and stock product in theU.S. through the Baum America Corp. Today they continue as a family owned and operatedbusiness and are currently managed by CEO Markus Baum.Baum offers complete manufacturing capability from steel to plastic. Paste extrusion is doneon specially designed extruders and lining uses highly automated production processes.Baum uses assets including state-of-the-art transfer molding to ensure speed to market.TodayBaum manufactures plastic lined pipe, fittings, vessels, dip tubes, valves and expansion jointsthat are protected from corrosion using PTFE, PFA, ETFE, PVDF or PP. All parts are supplied inaccordance with ASTM F1545-97 (2009).Before you purchase a corrosion resistant piping system we invite you to compare. Baum PTFE liners are paste extruded. This ensures permeation resistance that exceeds theisostatically molded PTFE products common in the US. This claim is supported by independent testing by the Korrosionsinstitutet of Sweden. Many of the Baum fittings will be upgraded to injection molded PFA. This is an even higherquality polymer with mechanical properties and permeation resistance that normally comeat a much higher price. Injection molding these fittings means that Baum products comewith full penetration welds unlike the welded over designs. Baum metal housings will feature rotating A105 forged steel flanges as standard. Mostdomestic producers typically charge for similar upgrades. Quality is verified by rigorous testing and assured with Insurance company certification.The Pressure Equipment Directive (PED) requires not only participation in an ISO qualityprogram but 100% traceability, spark and hydro testing, constant batch testing and permanent marking. Individual Baum components can be traced online for your convenience. Greater flexibility in design. (Schedule 10 stainless steel systems, DIN dimensions,electro-polished stainless steel exteriors, conductive PTFE, etc) is available.With Baum’s stringent quality programs, testing, traceability, and permanent marking thehighest level of safety and quality are assured. While other manufacturers provide productsthat simply comply with the current standards, Baum products search for solutions that willlast protecting personnel and the environment to a higher set of criteria. The bar has beenraised! Baum products represent the next level of safety and product quality.The Next Generation of Safety, Quality and InnovationMarkus BaumChief Executive OfficerBaum Kunststoffe GmbH
