The main structure and advantages of the forged steel Y-type strainer, the forged steel Y-type strainer is a kind of forged and forged parts which are produced by the forging method by screwing or butt welding and socket welding. The quality of forged steel parts is higher than that of steel castings, can withstand large impact forces and high temperature and high pressure, and its plasticity, toughness and other mechanical properties are also higher than cast steel Y-type strainer, so some important machinery and equipment It is best to use a Y-type strainer of forged steel as a filtering device in important and complicated working conditions. This product does not have external leakage caused by handling collision and casting sand holes. The  forged steel Y-type strainer  adopts a bolt-type valve cover. The valve designed according to this design form has a valve body and a valve cover bolted, a wound gasket (made of 304 plus flexible graphite) or a metal ring connection...

The valve selection is in full compliance with API603 requirements. The length is in accordance with ASME B16.10; the flange connection dimensions are in accordance with ANSI / ASME B16.5a. Valve inspection and testing are carried out in strict accordance with API598. Therefore, the valve is widely used in petrochemical pipelines, and is also applicable in electric power, metallurgy, textile and other systems. When the Stainless Steel Globe Valve  is opened, the opening height of the valve flap is 25% to 30% of the nominal diameter, and the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the full open position of the shutoff...

Understand the characteristics and operation mode of the forged steel Y-typeStrainer. The pipe with the forged steel Y-type Strainer can be divided into intermittent operation and continuous operation during operation. In the case of intermittent operation, a shut-off valve is provided before and after the forged steel Strainer to clean the filter. For continuous operation, two sets of filters in parallel are required for the permanent filter, and the shut-off valves are respectively arranged before and after the filter. Characteristics of forged steel Y-type Strainer: 1, full diameter or reduced diameter. 2. The socket end is in accordance with ASME B16.11. 3, bolted, wound gasket sealed bonnet. 4. The threaded end (NPT) conforms to ANSI/ASME B1.20.1. 5, can be equipped with discharge blockage, replaceable filter.

1. The integral flange forged steel valve is mainly applied to the pipelines of various systems of the thermal power station, cutting or connecting the pipeline medium. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, the integral flange forged steel valve is characterized by high temperature and high pressure and unique self-sealing design. The higher the pressure, the more reliable the seal. Due to the special technical characteristics and working conditions, the products also form features that cannot be replaced by other products. 2. Introduce the processing method of integral flange forging steel valve body forging, which is to take the blanking, pre-forging, final forging and trimming in turn. The characteristics are pre-forged initial blank after blanking, which is to forge the outer diameter of the material. It is larger than the outer diameter of the flange on both sides of the valve body, and then the middle portion is ...

API 602 Lift Check Valve with a Seal bonnet design and conforming to API 602 and ASME B16.34. it refers to the valve that automatically opens and closes the valve flap by means of the flow of the medium itself, and is used to prevent the back flow of the medium. The check valve belongs to an automatic valve, and its main function is to prevent the medium from flowing backward, preventing the pump and driving. The motor is reversed and the container media is vented. The check valve can also be used to supply piping to an auxiliary system where the pressure may rise above the system pressure. The function of this type of valve is to allow only the medium to flow in one direction and to prevent the direction from flowing. Usually, the valve is automatically operated, and the valve flap is opened by the fluid pressure flowing in one direction; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve disc act on the valve seat to ...
