Closed samplerFollowing the SH/T 0233-92 "Sampling Method for Liquefied Petroleum Gas" and "Safety Requirements for Sealed Sampling in Petrochemical Industry" standards, absorbing * technology, continuously improving design and upgrading processes to meet the needs of the domestic industry, we have successfully developed a sealed sampler (gas/liquid sealed sampler) that is safe, reliable, and easy to operate. To meet higher requirements and higher quality sampling. Suitable for leak free sampling of various media in petrochemical plants, especially toxic, harmful, flammable, explosive and other hazardous medium and low-pressure gas media. The collected samples have strong authenticity, high accuracy, and no residual liquid/gas emissions.

Gas sealed samplerSuitable for leak free sampling of various media in petrochemical plants, especially toxic, harmful, flammable, explosive and other hazardous medium and low-pressure gas media. The collected samples have strong authenticity, high accuracy, and no residual liquid/gas emissions. Effectively prevent the harm of toxic and harmful media to operators. At the same time, it will not pollute the environment and avoid dangerous accidents that may be caused by flammable and explosive media during sampling. Comply with national requirements for environmental protection, fire prevention, explosion prevention, and other regulations.

Gas sealed samplerWorking principle and characteristics:

Gaseous or volatile liquid media are collected in a sealed manner using seamless steel cylinders. The inlet and outlet ends of the seamless steel cylinder are controlled by safe and reliable needle valves, and equipped with stainless steel quick couplings, making installation and removal of the sampling steel cylinder safe, convenient, and fast.

The non-volatile liquid medium is collected using sealed pressure resistant bottles/ordinary open bottles, with excellent sealing performance. The stainless steel protective cover ensures the safety of operators.

Technical Specifications

Scope of application: Suitable for sampling liquids, gases, liquefied gases, and mixed gas-liquid media with most physical and chemical properties.
Sampling temperature: -20~450 ℃
Design pressure: 0-20.0MPa (to ensure sample circulation, it is required that the pressure difference between the inlet and outlet of the sample be greater than 0.01Mpa)
Sample size:300ml or 500ml

Structural composition: The closed sampler is based on an online sampler and consists of a box, valve fittings, sampling steel cylinder/closed pressure resistant sampling cylinder, flange, pressure gauge and other components.
