Quality defects of seamless perforated capillary tubes
Steel management properties: normal temperature mechanical properties, high temperature mechanical properties, low temperature properties, corrosion resistance. The physical and chemical properties of pipes mainly depend on the chemical composition of the steel, the organizational structure and the purity of the steel, as well as the heat treatment method of the pipe.Per saperne di più -
Confronto tra metodi di verniciatura per tubi in acciaio al carbonio
La verniciatura dei tubi in acciaio al carbonio si riferisce all'applicazione di uno strato di vernice sulla superficie dell'acciaio mediante spazzolatura, spruzzatura, ecc. per rendere il tubo d'acciaio più bello o aumentare la protezione. Il rivestimento può essere utilizzato nell'ingegneria edile, nella riparazione di automobili, nella decorazione della casa e in altri campi. La superficie dell'oggetto deve essere completamente pulita e rifilata prima della verniciatura per garantire che il rivestimento possa aderire saldamente alla superficie dell'oggetto.Per saperne di più -
Introduction to the grades of black steel pipes
Black steel pipe is commonly used in a variety of industrial applications, including pipelines, construction and infrastructure projects. When comparing Grade A and Grade B black steel pipe, it is important to consider their differences in chemical composition, mechanical properties and specific applications.Per saperne di più -
What are the ERW pipe making machines?
The ERW pipe forming unit initially adopted the chain drawing method. Later the United States created roll molding. The structure of the primary roll forming device is a cross arrangement of flat rolls and vertical rolls, and is mainly used to produce small diameter ERW welded pipes. After continuous improvement, the forming arrangement was changed to the form of flat, vertical roller + vertical roller group, the pipe diameter was developed from small diameter to medium diameter, and high-frequency welding was adopted. It is generally called a small and medium-sized roller forming welded pipe unit. Later, it was further developed into the row and roll type.Per saperne di più -
Acceptance standards for large diameter steel pipes
Large-diameter steel pipes (such as spiral welded pipes) are pipe products mainly used to transport liquids, gases, solids and other substances, and are usually made of steel. These pipes are commonly used in construction, petrochemical, industry, water supply, heating and other fields. The following is some relevant information about large diameter welded pipes:Per saperne di più -
How to prevent leakage of hydraulic tubes?
Hydraulic tubes are basically divided into fluid pipes and petroleum steel pipes used in hydraulic systems, also known as honing pipes. Cold-drawn or cold-rolled seamless steel pipes also include hydraulic steel pipes.Per saperne di più -
Qual è il margine di lavorazione dei tubi senza saldatura?
Per capire di quanti millimetri rimane generalmente il sovrametallo di lavorazione dei tubi senza saldatura, è necessario innanzitutto comprendere l'intervallo di tolleranza dimensionale del prodotto stesso. La tolleranza dimensionale di un prodotto si riferisce all'intervallo di deviazione consentito dalla dimensione effettiva del prodotto.Per saperne di più -
Tensile strength of stainless steel seamless pipes
There are many factors that affect the drawing force during the drawing process of stainless steel seamless pipes. According to research, some of these factors are beneficial to the drawing process. Conversely, other factors can make stretching more difficult.Per saperne di più -
Cast iron pipe vs Carbon steel pipe
Carbon steel pipes & tubes also called CS pipes, are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country's steel pipe industry.Per saperne di più
