Industry Qualification

The company's pipeline compensation equipment products mainly include metal bellows expansion joints (metal flexible connectors), high-temperature alloy bellows expansion joints, expansion joints for energy and chemical public pipelines, and expansion joints for thermal engineering.

Metal bellows expansion joints (metal flexible connectors) possess key technical characteristics such as high pressure resistance, high corrosion resistance, compact design, high reliability, and a lifespan comparable to the pipeline itself. They offer functions such as displacement compensation, vibration isolation, and low flow resistance. Primarily used in marine engineering, they solve the problems of displacement compensation and vibration reduction/isolation in pipeline systems under harsh conditions such as high temperature, high pressure, and corrosive media.

Expansion joints for energy and chemical plants possess key technical characteristics such as high temperature resistance, corrosion resistance, resistance to hazardous media, large diameter, high flow velocity, alternating operating conditions, online monitoring, high reliability, and modular pipeline compensation. They can achieve functions such as displacement compensation and vibration isolation. Primarily used in the energy and chemical industry, they solve problems such as limited system layout space, large compensation amounts, high stress, large equipment nozzle loads, and easy leakage in harsh operating conditions including high temperature, corrosion, flammable, explosive, and toxic media, high flow velocity, and vibration. They also solve the problems of coking, overheating, creep, and vibration control in large-scale, modular pipeline compensation devices for high-temperature hydrocarbon chemical plants.

Energy and chemical pipeline expansion joints possess key technical characteristics such as low stress, low flow resistance, large diameter, high flow velocity, adaptability to alternating operating conditions, high reliability, and pipeline lifespan. They enable displacement compensation and efficient transportation, primarily used in the energy and chemical industry. These joints solve problems encountered in large-diameter overhead pipeline systems under harsh conditions such as flammable and explosive, toxic, corrosive, high-temperature, and high-flow-velocity environments, including large compensation amounts, limited layout space, high flow resistance, and limited pipe gallery load-bearing capacity.

Thermal engineering expansion joints include heating expansion joints and steam expansion joints. They possess key technical characteristics such as low stress, low flow resistance, high pressure resistance, large diameter, large compensation amount, underground operation, online monitoring, and pipeline lifespan. They enable displacement compensation, low flow resistance, and low heat loss, solving the problem of long-term safe operation of high-temperature, high-pressure, large-diameter hot water pipeline systems for over 20 years.
