| Metal Expansion Joints A metal compensator is a type of compensator made of metal corrugated pipes. There are two types of connection methods, namely flange connection and welding connection. It can expand and contract along the axis of the pipeline, and also allows for slight bending. A common axial ripple compensator is used for axial length compensation on pipelines. In order to prevent exceeding the allowable compensation amount, protective rods or rings are installed at both ends of the corrugated pipe, and guide brackets are set on the pipes connected to it at both ends. In addition, there are corner and transverse expansion joints that can be used to compensate for the corner and transverse deformation of pipelines. Due to its advantages of reliable operation, good performance, and compact structure, metal compensators have been widely used in industries such as chemical, metallurgical, and nuclear energy as an elastic compensation element that can freely expand and contract. There are various forms of ripple compensators used on containers. In terms of the shape of the ripple, U-shaped expansion joints are more widely used, followed by Ω - and C-shaped ones. In terms of structural compensation, the corrugated compensators used on pipelines can be divided into pressure balanced, hinged, and universal joint types. |

| Non-metallic compensator A non-metallic compensator is a flexible component composed of a composite non-metallic fabric and two connecting pipes (or flanges) and insulation materials that can be connected to adjacent pipelines to form equipment. It is mainly used to compensate for the displacement caused by temperature, mechanical vibration, and foundation sinking in pipelines and equipment systems transporting micro pressure dust gases, smoke, gas, and other gases. Among them, non-metallic ring belts and insulation materials are commonly composed of various materials such as glass fiber cloth, polytetrafluoroethylene film, composite rubber glass fiber cloth, aluminum silicate fiber cotton, etc. according to different working temperatures. The material of metal structural components is usually recommended to be t ≤ 400 ℃, using Q235-A; When t ≤ 450 ℃, material 10 or Q345 (16Mn) should be selected. Other materials should be used as special designs. |

| Metal Hose The metal hose adopts an all metal structure, consisting of three main parts: corrugated pipe, mesh sleeve, and joint. Bellows are the main body of metal hoses, playing a flexible role; The net sleeve plays a role in strengthening and shielding; The joint plays a connecting role. The way they connect to each other varies for different usage requirements. It is mainly processed and manufactured with stainless steel as the main material, and is generally used in soft joints. The specific material grade can vary greatly in price and performance. Metal hoses have excellent flexibility, corrosion resistance, (-235 ℃~+450 ℃), and high pressure resistance (up to 32MPa). They can be connected in various directions in pipelines to compensate for temperature and absorb vibration, reduce noise, change the direction of medium delivery, eliminate mechanical displacement between pipelines or between pipelines and equipment, etc. Double flange metal corrugated hoses are particularly suitable for flexible joints of various pumps, valves, etc. with displacement and vibration. Metal hoses are formed by high-precision plastic deformation processing of seamless or longitudinally welded stainless steel thin-walled pipes. The elastic characteristics of the corrugated pipe profile determine the flexibility of stainless steel soft connections. |

| Ventilation butterfly valve Ventilation butterfly valves, also known as dampers, are divided into electric dampers, pneumatic dampers, and manual dampers. Ventilation butterfly valves are mainly used in power plants, boiler air ducts, and flue to intercept or regulate medium flow, and can also be used in air ducts and flue in other industries. A circular damper can allow all the medium in a certain pipeline of the system to flow/cut off, or the medium flow rate to change with control. For ventilation butterfly valves with smaller diameters, they have two functions: interception and regulation of medium flow. For circular air doors with larger diameters, their regulation function is not very obvious, and their interception function is mainly used. The ventilation butterfly valve has the advantages of simple structure and convenient operation. Widely used in metallurgical, power plant petroleum, chemical and other sectors. Applicable media include gas, dusty gas, flue gas, etc. |

| rubber compensator Rubber compensators are mainly used in pipelines to reduce vibration, reduce noise, have good elasticity, and are convenient to use. Flexible single ball rubber joint is a pipeline joint with high elasticity, high airtightness, medium resistance, and weather resistance. There are many types of rubber compensators, but the prices of rubber compensators with the same caliber and model are different, which is closely related to the materials used in the product. The rubber compensator produced by Hebei Zhonghao strives for excellence in pressure, medium, temperature, flange material, and ball material, delivering good products to customers. |
 |
| gate valve Plug valve, also known as gate valve or spiral plug valve, is mainly composed of components such as frame, gate plate, screw rod, nut, handwheel, etc. By rotating the handwheel, the screw rod drives the gate plate to move up and down repeatedly along the water surface, achieving the purpose of opening and closing the plug valve. The plug valve is a main control equipment for the flow or conveying volume of powder, crystalline particles, granular materials, and small materials, widely used in metallurgy, mining, building materials, and grain. Plug in valves are usually used in conjunction with unloaders. The diameter of the plug in valve matches the feeding port of the unloader, and there are two types: square and circular. |
