DN100 conventional small-diameter straight seam welded pipe, stable batch production
DN100 (outer diameter 114.3mm) is one of the small-diameter specifications of Huayang Steel Pipe in daily mass production, and is widely used in low- and medium-pressure oil and gas transportation, municipal construction, industrial supporting and other fields. Huayang is equipped with a dedicated 114mm welding pipe unit, with high pipe diameter control accuracy and strong batch consistency, and supports flexible customization of wall thickness from 3.0mm to 8.0mm. This specification is shipped frequently and is a common specification that is frequently selected in many overseas OGTC projects. Its advantages are convenient construction, flexible connection and high transportation efficiency.
High-frequency welding forming, dense and neat welds
DN100 pipes usually use high-frequency resistance welding (ERW) technology. During the production process, the edge of the steel strip is heated by high-frequency current and then welded by extrusion forming. No welding material is needed, and the weld is almost the same strength as the parent material. Huayang's welding line is equipped with online eddy current detection and laser diameter gauge, combined with water pressure testing and manual sampling to ensure that each DN100 pipe has standard size, no defects in welds, and a neat appearance.
In the construction of oil and gas infrastructure such as OGTC, DN100 steel pipes are often used in scenarios such as branch line connections within stations, natural gas pressure regulating cabinets, gas boiler inlet pipes, and oil product return branches. Its small and flexible size is suitable for both single laying and crossing complex areas of municipal and factory areas. We have provided a large number of pipes of this specification for Ghana natural gas terminals, Angola oil field gathering and transportation systems, and Pakistan city gas projects, and the feedback from use has been good.
Huayang Steel Pipe has an intelligent welded pipe production base in Cangzhou, Hebei, and DN100 steel pipes are in sufficient stock all year round. We support factory processing such as spray painting for anti-corrosion, coding and marking, groove processing, capping and capping, and provide supporting services such as English warranty, third-party testing, and export packaging. During the project execution, the entire process is traceable, and the business team and technical engineers provide dual-track support to ensure that each order is delivered on time, with quality compliance and in place services.
