采用腐蚀挂片和表面能谱分析等实验测试方法，研究了四氢噻吩（ＴＨＴ）加臭剂对天然气管网用材的腐蚀行为研究结果表明在碳钢、黄铜、紫铜、铝、聚乙烯、聚氯乙烯和石棉等材料在富 ＴＨＴ的天然气（ＴＨＴ浓度约１ｇ／ｍ３）中是基本耐蚀的。在浓度小于４００×１０－６的ＴＨＴ－石油醚溶液中碳钢、黄铜、紫铜和铝材均耐蚀，但聚氯乙烯试件耐蚀性较差。在纯ＴＨＴ中紫铜和聚氯乙烯不耐蚀，碳钢也发生锈蚀。研究发现只有当碳钢试片浸在很高浓度的ＴＨＴ－石油醚溶液中发生锈蚀时，其表面才有大量ＴＨＴ牢固吸附存在。在ＴＨＴ浓度小于１５００×１０－６的ＴＨＴ－石油醚溶液中，碳钢表面不发生锈蚀，同时也不存在ＴＨＴ特性吸附。如果输送天然气的碳钢管道有锈蚀现象存在，就有可能造成 ＴＨＴ加臭剂的一定损耗，要在确定ＴＨＴ加臭量时加以考虑。
The corrosion behavior of natural gas pipeline materials by THT odorants was studied by using experimental methods such as corrosive coupons and surface energy spectrum analysis. The results show that corrosion resistance of carbon steel, brass, copper, aluminum, polyethylene, Materials such as PVC and asbestos are essentially corrosion-resistant in THT-rich natural gas (about 1 g / m3 THT). In the concentration of less than 400 × 10-6 THT-petroleum ether solution of carbon steel, brass, copper and aluminum are corrosion resistance, but poor corrosion resistance of PVC specimens. In pure THT copper and PVC are not corrosion-resistant, carbon steel corrosion also occurs. The study found that only when the carbon steel specimen immersed in a very high concentration of THT-petroleum ether rust occurs, the surface of a large number of THT solid adsorption exists. In THT-petroleum ether solution with the THT concentration less than 1500 × 10-6, no corrosion on the surface of the carbon steel occurs and there is no THT adsorption. If the transmission of natural gas carbon steel pipe rust exists, it may cause a certain THT odorant loss, to determine the amount of THT added to be considered.
