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.Читать далее -
Сравнение способов окраски труб из углеродистой стали
Окраска труб из углеродистой стали подразумевает нанесение слоя краски на поверхность стали путем нанесения кистью, распылением и т. д., чтобы сделать стальную трубу более красивой или повысить ее защиту. Покрытие может использоваться в строительном машиностроении, ремонте автомобилей, отделке дома и других сферах. Перед покраской поверхность объекта должна быть полностью очищена и подровнена, чтобы покрытие прочно прилегало к поверхности объекта.Читать далее -
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.Читать далее -
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.Читать далее -
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:Читать далее -
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.Читать далее -
Каков припуск на обработку бесшовных труб?
Чтобы понять, сколько миллиметров вообще оставляют припуск на обработку бесшовных труб, нужно сначала разобраться с диапазоном допусков размеров самого изделия. Допуск на размер продукта относится к допустимому диапазону отклонений фактического размера продукта.Читать далее -
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.Читать далее -
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.Читать далее
