Piping welding - Import export

This is a welded pipe made of stainless steel,mainly used for connect both of the two sides od the products.

Stainless steel flanges are a crucial component in various piping systems, providing ease of assembly and strength in connecting pipes, valves, pumps, and other equipment. They serve as a plate for covering or closing the end of a pipe and are commonly used in plumbing, oil and gas, petrochemical, and food industries due to their durability and corrosion resistance. Types and Specifications Stainless steel flanges come in several types to suit different applications: Weld Neck Flanges: Designed to be welded to the pipe. Suitable for high-pressure applications. Slip-On Flanges: Easily slide over the pipe and are welded in place. Socket Weld Flanges: Used for smaller, high-pressure piping. Threaded Flanges: Attached without welding, ideal for low-pressure applications or pipes with a thin wall. Blind Flanges: Used to seal the end of piping systems or pressure vessel openings. Lap Joint Flanges: Used with stub end fittings for applications requiring frequent dismantling.

We can supply pipes for the construction of pipelines, equipment and tanks subject to low temperatures as Seamless or welded pipes, hot rolled or cold finished. Pipe norms suitable for low temperatures are according to; ASTM A 333 / ASME SA 333 (seamless and welded pipes) EN 10216-4 (Seamless pipes) EN 10217-4 (Welded pipes)

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)

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.

Combination of welding outlet and flange Nipoflange in pipeline construction A nipoflange is used in pipeline construction just like a welding outlet or a nipple outlet for a 90 ° branch. A Nipoflange is a combination of welding outlet, nipple outlet and flange. Further terms for Nipoflange are Weldoflange or Flangeolet. Two different branch sides On the pipe branch side , a nipo length has the shape of a welding outlet. This means that the branch from the pipe is made with a welded joint. There is a flange on the connection side, ie a flange connection is created. The flange can be designed according to customer requirements (usually according to DIN or ANSI). Nipoflange as a forged fitting A nipoflange (similar to ANSI B 16.9 / MSS-SP 97) is usually made from a forged blank. This means that a Nipoflange is a forged fitting and has no welds.

Swept outlet similar to ANSI B 16.19 / ANSI B 36.10 Swept outlets in pipeline construction A swept outlet is used in pipeline construction just like a welding outlet, a socket welded outlet or a threaded outlet for a 90 ° branch. A swept outlet is an alternative to the T-piece / red. In comparison to the T-piece / Red.Tee, the installation effort for a swept outlet is lower because only one hole has to be drilled into a pipe. The swept outlet can then be welded into this hole. A swept outlet differs from a welding outlet in the type of welding. While a welding outlet is only placed on the run pipe and then welded, a swept outlet is welded directly into the run pipe. Ideal stress distribution Swept outlets were developed in order to achieve the best possible stress distribution for internal pressure and pipe forces. Due to the favorable voltage level, swept outlets are often used in highly stressed pipes in the oil and gas industry.

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).
