the raw materialthe raw material

Although traditional tubing materials like copper are adequatefor some high purity applications,the material of choice in thesemiconductor andbiopharmaceutical markets is 316Lstainless steel.

Readily available, 316L is a lowcarbon steel alloy, attractivebecause of its good weldability andinherent corrosion resistance.However, commercially available316L may contain impurities in theform of trapped gases and non-metallic inclusions. To preventthis from becoming a problem forour customer, we select onlyspecific grades of 316L andpurchase materials to our ownspecifications.

Cardinal UHP produces ultra highpurity tubing from many materialsbesides 316L. For example, we alsouse 304SS, Hastelloy, Monel, andcopper. Prior to placing any materialin production we test representativesamples to determine their wallthickness, ovality, weldability andcompatibility with ourelectropolishing process and desiredRA finish.

from concept to reality

from concept to reality

Cardinal UHP has been supplying avariety of industries with specialtypiping components and services forover 20 years. We introduced multiplebest practice methods that are nowrecognized as industry standards.

Cardinal continues to supply the finestin ultra high purity fittings and pipingcomponents to manufacturers andindustries requiring critically pureproduction systems. We also supply awide range of tubing and specialtyservices for other markets includingmedical, food processing,biotechnology, pharmaceutical,semiconductor, and telecommunication.

Our ISO 9001 quality system beginswith the specifications for raw materials and continues through topackaging, delivery and support of thefinished product.

Quality starts with a finished product specification. To meet customer needsCardinal UHP offers products to avariety of material and finish specifications with various levels ofdocumentation.

Raw material specifications are developed to provide the lowest costproduct that meets or exceeds the finish and elemental specification.Extensive inspection of the raw materialinsures a finished product that meetsthe specified requirements.

Mechanically polishing fittings afterbending and welding provides anexcellent base for the finalelectropolishing and passivation steps.

Controlled electropolishing andpassivation provide a smooth, cleanand chromium enriched corrosionresistant surface. The finished productis cleaned one last time in our ISOClass 4 clean room, tested andpackaged according to specificationbefore it is ready to ship.

It is our consistent attention to detail atall phases from commercial review tomanufacturing and sales support thatturn a concept of quality into reality.

Electropolishing creates a smoothclean surface that enhances corrosion resistance and reducesparticle entrapment in microscopiccrevices. With our innovative andproprietary ALC-300 process,Cardinal UHP greatly increases theability to deliver quality electropolished components fordependable performance in any critical distribution system.

The Cardinal UHP system creates aleveling action so effective that anelectropolished surface often hasonly one tenth the surface area of amechanically or chemically polished surface. During the electropolishing process the wall

research & developmentresearch & development

As part of our extensive ongoingresearch and development programs Cardinal UHP has funded metallurgy research at theUniversity of Missouri’s Center forMaterials Research. Our surface treatment studies focused onincreased standardization in theelectropolishing process toachieve a predictable andconsistent finished product. Twoareas that have been targeted todate are the variables involved inthe process and the effect that rawmaterials have on the finalproduct.

The knowledge gained through ourresearch efforts led to the creationof the first ALC-300 digitally controlled electropolish processmonitoring equipment. The ALC-300 is capable of producingconsistent quality productswithout variance from operator tooperator.

Through our research efforts, wedemonstrated that manyinconsistencies in the final productare directly attributed to variationin microchemistry and grain sizeof the raw material. This is why wetake special care to procure onlymaterials providing optimalconditions for electropolishing.

Today we have improved on theindustry specifications for rawstainless steel alloy, establishingour own proprietary standards formaterial procurement. Our continuing investigation of theeffects of process variables allowsCardinal UHP to transform the artof electropolishing into a controlled science.

Our ALC-300 controller uses statistical process control to bringthe electropolishing process into thetwenty-first century. Every vitalparameter is monitored and regulated with this innovative computer controlled system. Sinceprocess parameters are stored in adatabase, the ultimate in materialtracking is available.

It’s about safety.

Because of the high degree of purityand low surface roughness, Cardinaltubing is widely used insemiconductor, pharmaceutical,medical, food processing,biotechnology, andtelecommunication industries. Weproduce tubing to eight differentspecifications providing economicsolutions for everything frommission critical applications toinstrumentation and bulk gasdelivery systems.

Standard sizes range from 1/8"through 6" (3mm - 150mm) singlewall tubing with electropolishedsurface roughness as low as Ra5µin / 0.13 µm in 316L SS andHastelloy C22. We produce tubingwith the full range of cleanlinessspecifications from T/C cleaning todouble bagging and capping tubingto SEMI specifications in our ISOClass 4 clean room.

Cardinal fittings are formed frommaterial that meets the sameexacting standards as our processtubing. We begin the process with aheavier wall to offset the thinningthat occurs during manufacturing.Cardinal UHP fittings undergo athorough preparation process toinsure corrosion resistance as wellas stringent dimensionalspecifications for economicalinstallation.

Welds are mechanically polished,and when required, fittings areelectropolished and passivated. Allwelds are 100% visually inspectedand mass spectrometer helium leaktested. Finally, the fittings arecleaned, capped, and bagged tomeet the required specification.

EP Pak uses the same UHP criticaltubing (including dual containmentconfigurations) Cardinal is knownfor in a pre-insulated andelectrically heated package. EP Pakis delivered in long continuouslengths to improve utilization andreduce scrap rates.

Our factory installed electric heattracing is applied under controlledconditions and provides heattransfer efficiency and consistencythat cannot be duplicated with fieldconstructed systems. There are nocold spots created by tubingsupport clamps or gappinginsulation.

It’s about innovation.

Cardinal UHP has developed aproprietary method ofelectropolishing tubing in longcontinuous coils. The finished10µin / 0.25µm Ra finish iscomparable to our electropolishedstick tubing. This new developmentmeans fewer welds, quickervalidation and reduced installationlabor for UHP piping systems. Theprocess validation for Cardinal EPCoil is identical to that used forstick tubing so you know you aregetting a reliable finished product.

Cardinal UHP can provide longcontinuous lengths ofelectropolished tubing in fractionalsizes from 1/8” through 1/2” and inmetric sizes from 3mm through12mm with continuous lengths upto 330’ or 100 meters.

EP Coil is also available in coaxialor dual containment configurationsfor hazardous and volatile serviceapplications.

Cardinal UHP coaxial dual containment tubing and fittings arespecified for the safe distributionof volatile or toxic gases. In theunlikely event of a leak in theprocess tube the hazardousgas/fluid is contained by the outertube and evacuated for safedisposal.

Cardinal UHP created a speciallydesigned spacer between theprocess and containment tube tomaintain a consistent annularspace and eliminate excess vibration and noise.

Process tubes have the samesurface finish and specifications asour single wall tube and fittings.Dual containment tube and fittingsare available in all configurationsand sizes.

Cardinal UHP was the first company in the high purity tubingand fitting industry to adopt aninternationally recognized ISOquality management program. Ourunyielding commitment to quality isevident in every step of ourmanufacturing process. From thestart of procurement we specifystringent material standards. Whenraw materials arrive at our loadingdock they are quarantined until wallthickness, ovality, smoothness, surface morphology, and chemicalcomposition have been verified toinsure it will meet our rigorouselectropolishing procedures.

All measuring instruments and analytical equipment are calibratedand traceable to NIST standards.Finally, every employee is empowered to declare piping andfittings unfit for sale if deviationsfrom our standards are discovered.
