In de offshore en binnenlandse alluviale vlakte regio, de dikte van 50 ~ 60 m zachte bodemlaag van de bovenste belasting is groot en kan niet direct als een dragende laag, de lage compressie dragende laag is altijd diep, waar meestal gebruik maken van de algemene structuur van stalen paal met een heihamer het produceren van een grote impact op. Stalen buispaal versterking [...]
De sterkte van staal verwijst naar de vervorming en breuk van metalen materialen onder invloed van externe krachten, die over het algemeen de treksterkte, buigsterkte en druksterkte omvatten. Hoe beter staal bestand is tegen externe krachten, hoe sterker het staal is. Dus hoe kunnen we de sterkte van staal verbeteren? Oplossing Het versterken van de [...]
Sulfide stress cracking (SSC) is a form of hydrogen embrittlement cracking. Sulfide stress cracking occurs in low alloy steel pipeline, high-strength steels, weld joints, and welding heat-affected zones (HAZs) subjected to tensile stress in acidic environments and temperatures below 82°C (180°F), depending on the composition, microstructure, strength, residual stress, and external stress of the steel. The […]
API 5A J55 is a commonly used casing material. The tubing body is threaded to the coupling and must be welded to reinforce the strength of the threaded connection. A harsh working environment requires high quality for the pipe body and welding quality. We analyze its weldability by calculating carbon equivalent. The chemical composition of J55 casing is shown […]
Hydrogen can be gaseous hydrogen, liquid hydrogen and solid hydrogen according to the state when transportation, among which high-pressure gaseous hydrogen is the most commonly used and environmentally friendly transportation mode at present. Pipeline transportation is the most efficient way for a large throughput and distance occasions can be a long-distance pipeline, also be a short distance […]
Line pipe is a type of steel pipe that is used for transporting materials through pipelines across the country. Line pipe can be used to transport petroleum, natural gas, oil, and water. It is a durable pipe that must meet certain specifications and regulations. This pipe typically has a high strength and durability in order […]
What is Line Pipe: Line pipe is a type of pipe that is manufactured from high strength carbon steel. It is typically made according to metallurgical specifications that were developed by the American Petroleum Institute (API). Line pipe can be used to build pipelines that transport a variety of resources including natural gas, oil, petroleum, […]
The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe. This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil. Size range is limited only by manufacturer’s capabilities. Specifications for API 5L adhere to the International […]
