Although the peak period of building sheds has not arrived yet, many vegetable farmers have started to prepare shed materials. How should farmers choose how to buy steel pipes?
It is understood that there are mainly three types of steel pipes currently on the market: one is a galvanized steel pipe, the second is an oil field pipe, and the third is an ordinary iron pipe.
Galvanized pipe prices are the highest. Nowadays, hot dip galvanized pipes are mainly sold on the market. Such galvanized steel pipes are not easily detached, have strong rust-proof ability, are strong in pressure resistance, are not easy to bend, and have a long service life. They are recognized by most vegetable farmers. When choosing this type of steel pipe, the vegetable grower should choose different diameter steel pipes according to the shed width. Generally, the width of the shed is more than 10 meters. To increase the pressure resistance of the greenhouse, a steel pipe with a diameter of 5 cm should be selected; and the shed width should be less than 10 For meters, a 4.5-cm diameter steel pipe can be used. Before use, it must be bent beforehand according to the arch of the shed.
The diameter of the oil field tube is small, and some wall thicknesses can reach about 0.8 cm. The elasticity is strong. It can be used without being bent before installation. The disadvantage is that the anti-rust ability is poor. After the steel pipe rusts, the shed film will be contaminated, so it is necessary to apply anti-rust paint in time. This type of steel pipe is easy to install and use, but it needs to pay attention to the post-conservation.
The price of ordinary iron pipe is the lowest, but there is no anti-rust ability. When using it, it must be bent and shaped according to the arch of the shed in advance. At the same time, anti-rust paint must be applied in time to prolong the service life of the iron pipe.
When building a shed, farmers should consider comprehensively and choose the right steel pipe material. It is most convenient to use galvanized steel pipe.
Medical Ultrasound (also known as Diagnostic Sonography or Ultrasonography) is a diagnostic imagingtechnique based on the application of ultrasound. It is used to see internal body structures such as tendons,muscles, joints, vessels and internal organs. Its aim is often to find a source of a disease or to exclude anypathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and is widely used.
