Pipeline construction - Import export

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.

In order to protect pipelines from damage (e.g. during construction activities), they are regularly inspected on foot, from a vehicle or helicopter. Practical experience has shown, however, that these methods do not ensure continuous and comprehensive monitoring. PipeMon+® closes this gap, allowing appropriate measures to be taken immediately when a pipeline is suddenly damaged. OGE has developed a pipeline monitoring method based on the principle of cathodic protection (CP). When a cathodically protected pipeline is damaged by construction equipment (excavator, drill, rotary cultivator, etc.), the protective current distribution on the pipeline changes. Using appropriate sensors and special analysis methods, these events can be detected in real time.
