High-precision tubes Smal l diameter

Seamless and welded steel tubes Zeleziarne Podbrezova is a private shareholding company located in the Central Slovakia region. The main production focuses on producing seamless and welded steel tubes. The company’s main advantage is that it owns a modern steel shop that can quickly react to secure all necessary raw materials for the production of seamless steel tubes. Part of the company’s production of hot rolled seamless tube is sold directly to customers, and part is used as semi- finished product for the production of cold drawn precision seamless steel tubes. Outside diameters of these precision tubes range from 3 to 120mm (0.120" to 4.75"), and wall thicknesses range from 0.5 to 10mm, depending upon the outside diameter. The length of the tubes can be up to 18m, also depending upon the diameter. The tubes are made out of carbon and low alloy steel. In addition to seamless tubes, the company makes precision welded tubes in two versions: cold calibrated and cold drawn. The latter can be supplied in diameters starting at 4mm. Precision tubes are produced and delivered according to all appropriate international standards – EN 10305 – 1, 2, 3 or according to other national European standards and to USA and JIS standards.

60 years of small tube experience

Small Tube Products (STP) is a tube mill producing OD sizes as small as 1mm (0.04"). Serving industry for over 60 years, the US-based company operates as a make-to-order mill, producing custom size non-ferrous tube (copper, brass, bronze, cupronickel and titanium) and tube fabrications. STP’s key strengths are its manufacturing process know- ledge, tooling design and tooling fabrication skills.

Ultra high purity tubing for the pharmaceutical and biotechnology industries

2 mil poly sleeving which is boxed in heavy wall cardboard sleeves. For its ultra high purity tubing, RathGibson electropolishes its 6" OD tubing to a SFT4 finish with a 15μ-in Ra (0.4μm) ID maximum and 30μ-in Ra (0.8μm) OD maximum. Before being placed in heavy wall cardboard sleeves for shipment, the tubing is processed in an ISO Class 5 cleanroom to ensure airborne particles 0.5 micron or larger are not present. “Our 6" high purity and ultra high purity tubing is ideally suited for pharma and biotech applications,” commented Paul Sedivy, director – high purity products. “The weld formed by our proprietary process withstands the toughest treatment, as evidenced by the results garnered from the full range of testing performed on each tube.”

RathGibson, a manufacturer of welded, welded and drawn, and seamless stainless steel, nickel, and titanium tubing and pipe, offers 6" OD tubing for high purity and ultra high purity applications in the pharmaceutical and biotechnical industries. The company’s 6" OD product line includes both SFT1 and SFT4 finishes that fulfil the stringent ASME BPE and ASTM A270 S2 specifications. Crafted with 316L stainless steel, the 6" OD tubing is bore scoped and polished to minimise surface anomalies and reduce corrosion and pathogen contamination. MechanicallypolishedwithRathGibson’s proprietary finishing processes, the 6" OD high purity stainless steel tubing is SFT1 finished with 20μ-in Ra (0.5μm) ID maximum and 30μ-in Ra (0.8μm) OD maximum.

Specific types of technical or shipping conditions can be negotiated.

The company’s tubes can be delivered as semi-finished products that are made out of the raw tubes by splitting, shearing, modification of the tubes ends and bending.

The precision tubes are shipped directly, or through the company’s subsidiaries.
