Carbon steel butt welding pipe fittings are the most widely used pipe fittings. It is made of high-quality steel pipe and is formed by heating or pressing. Carbon steel pipe fittings are divided into carbon steel elbow, carbon steel tee, carbon steel cross, carbon steel reducer (large and small head), carbon steel head (cap) 5 series. The main implementation standards include GB, DIN, ASME, JIS, GOST. The biggest use of carbon steel pipe fittings is to connect pipes, Valves, pumps and other equipment to form a complete piping system.

1. Turbine flowmeters are generally used only for low-viscosity single-phase fluids
Through the practical application and verification of turbine flowmeters, when measuring low-viscosity media, the meter factor hardly changes with the flow rate. When the viscosity of the measured medium increases, the linearity of the turbine flowmeter becomes very poor. The meter factor will also change greatly with the change in flow rate, making it difficult to achieve the required measurement accuracy. When the medium to be measured is gas-liquid two-phase flow, the flow rate of the medium will become very unstable, resulting in a large measurement error.
2. The medium fluid measured with turbine flowmeter should be in turbulent state
According to the flow characteristics of the turbine flow meter, it can be seen that when the medium is in the laminar flow state, the meter coefficient changes greatly with the change of the flow rate. When the medium is in the turbulent flow state, the meter coefficient does not change with the flow rate. In order to ensure the measurement accuracy of the turbine flow meter, the measured medium should be in a turbulent state.
3, turbine flowmeter is generally only used to measure the cleanliness of the medium
At present, the bearings of most turbine flowmeters are ball bearings and therefore have high requirements on the cleanliness of the measured medium. If the media contains particulate impurities, the bearings will wear quickly, if there is fiber impurities will be wrapped around the turbine blades, affecting the normal rotation of the turbine. In practical applications, an effective filter should be installed upstream of the turbine flowmeter.
When using, the pipe fittings are evenly welded with the flange or directly with the pipeline, so that the entire pipeline is integrated and starts to work normally.
Carbon steel pipe fittings are widely used in water, beverage, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, waterproofing and other pipeline systems. It is the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments. The tube cap is also the end cap on the pressure vessel, which is a main pressure-bearing component of the pressure vessel. The quality of the cap is directly related to the long-term safe and reliable operation of the pressure vessel.
