Manufacture of pipes - Import export

We manufacture stainless steel branch pipes as well as stainless steel T-pieces with the following characteristics: 30°, 45°, 90° degrees (standard) material-no. AISI 304 / 304L at request also in aluminium at request also forming gas welded

Applications Pipes for the construction of pipelines for water, liquid hydrocarbons, natural gas and for the construstion of chemical and industrial plants, refineries etc. Norms Line pipes are according to the following norms: API 5L (ISO3183) (seamless and welded pipes) ASTM A53 / ASME SA53 (seamless and welded pipes) Manufacturing methods Seamless pipes, hot rolled or cold finished with following heat treatment: ERW pipes up to dia 24" and SAW pipes for the other sizes.

We supply the pipes that are suitable for bending and are used for the constructions of plants and equipment subject to high temperatures and pressures. The seamless pipes, hot rolled or cold drawn/cold finished with heat treatment. The ASTM A335/ASME SA335 and EN 10216-2 norms require heat treatment also for the hot rolled pipes. The welded pipes are manufactured according to EN 10217-2. Supply of pipes suitable for high temperatures are according to; ASTM A 106 / ASME SA 106 (Seamless pipes) ASTM A 335 / ASME SA 335 (Seamless pipes) EN 10216-2 (Seamless pipes) EN 10217-2 (Welded pipes)

Siempelkamp is number one in tailor-made plants for the leading manufacturers of pipeline pipes. These large-diameter pipes with longitudinal weld seams are manufactured using crimping, U-forming, and O-forming presses. Compared to other processes on the market, these three presses achieve high production outputs of up to 30 pipes per minute regardless of the pipe diameter. For these large presses featuring our proven metal frame construction, the heavy component parts and tools are manufactured in our in-house foundry. The three hydraulic presses present the essential forming units of a modern production line for longitudinally welded pipes with lengths of up to 18 m in three forming steps. For each of the three forming steps, Siempelkamp oers the optimal press and the associated equipment for the forming line (e.g., pipe transport, lubrication, measuring).

All components pass a quality inspection before being used. Many different methods and procedures are used here (e.g. PMI 0 positive material inspection, crack detection). Our scope of machining reaches from chipping/metal cutting to sandblasting (using granule materials) to welding, assembling and painting. We handle many different metallic and nonmetallic materials as steel, stainless steel, duplex materials, titanium, plastic material We give a big importance to welding: Nash employees are certified according to ASME 9 and therefore qualified to manufacture pressure vessels and piping according to Pressure Equipment Directive (DIN EN 3834) and ASME Standards (31.3). Our systems are painted according to customer specification. We work with all wet paints and 2K paints. Anti-corrosion-coatings up to category C5M are possible. Of course, we meet all the other specifications, e.g. regarding coating thickness, as well. The electrical engineering is also done in the Nash location, from design to cabling. After the completion, the system undergoes a pressure test. Furthermore there is an option to do a complete function test to verify the performance data. Nash is certified according to ISO 9001 and ISO 14001.
