Forged steel pneumatic ball valve is applicable to various pipelines with pressure rating of CLASS600LB, CLASS800LB, CLASS900LB, CLASS1500LB, and operating temperature of - 46 ℃~180 ℃ (seal ring includes RPTFE, MOLON, PEEK), - 46 ℃~425 ℃ (seal surface is hard seal), mainly used to cut off or connect the medium in the pipeline. The corresponding forged steel pneumatic ball valve can also be designed and manufactured according to the user's actual working conditions and special requirements. It can be made of different materials and can be used for water, steam, oil, nitric acid, acetic acid and other media.

Development status of non-metallic compensator
The non-metallic compensator is used to absorb the thermal displacement to eliminate the flexible connection of stress in the pipeline or equipment system, and also can isolate, shock absorption and absorb the error of the pipeline device. It is generally composed of synthetic rubber, fiber fabric, thermal insulation materials, fluoroplastics and other non-metallic materials. At present, the non-metallic compensator product technology has been relatively mature, and is widely used in steel plants, At the entrance and exit of smoke removal and desulfurization, dust removal equipment, air heating, flow aid blower and other equipment in smelters, petrochemical plants, thermal power plants, cement plants and atomic power plants,
Its structure, performance and quality can meet the requirements of many engineering fields. With the development of application sites from time to time, the demand for non-metallic compensators is increasing year by year. Therefore, enterprises designing and manufacturing non-metallic compensators are increasingly checking the market of metal compensators, spherical compensators
1. The model, specification and pipeline configuration of the compensator shall be checked before installation, which must meet the design requirements.
2. For the compensator with inner sleeve, attention shall be paid to make the direction of the inner sleeve different from that of the medium, and the hinge rotation plane of the hinge type compensator shall be different from that of the displacement rotation plane.
3. For the compensator that needs to stop "cold tightening", the auxiliary components used for pre deformation shall be removed before the end of the pipeline device.
4. It is forbidden to adjust the device out of tolerance of the pipeline by means of deformation of the corrugated compensator, so as not to affect the normal function of the compensator, reduce the service life and increase the load of the pipeline system, equipment and supporting members.
5. In the process of installation, welding slag is not allowed to splash on the surface of the corrugated shell, and the corrugated shell is not allowed to suffer from other mechanical damage.
6. After the completion of the pipe system device, the yellow auxiliary positioning components and fasteners used for device transportation on the corrugated compensator shall be removed as soon as possible, and the limit installation shall be adjusted to the regular position according to the design requirements, so that the pipe system has sufficient compensation ability under environmental conditions.
The impact of the economic crisis caused the steel industry to enter the trough, and the spherical compensator market was once vibrant. In the past six months, with the slow rise of the economy, the spherical compensator market has shown signs of recovery, but the uncertainty is still large. Today, water supply and drainage will briefly analyze the macro situation of the spherical compensator market for your reference.
