Before entering such “carriages”, they are “armed”!
“Lao Yang, time is up, hurry up!””Shouted Masonko, standing at the mouth of the jar.His workmate, Yang Jianjun, then struggled out of the tanker’s entrance, covered in mud.Yang Jianjun put down his cleaning tools and took off his gas mask. His head was emitting hot bursts of sweat pouring out of the brim of his hat.This is how can washer Yang Jianjun spends his Spring Festival travel rush.Yang Jianjun, 53, has been washing cans for train tankers for 31 years.Simple and introverted he smiled with a simple and honest strength, everyone affectionately called him “Old Yang”.Lao Yang is China Railway Lanzhou Bureau Group Co., LTD. Lanzhou west vehicle Duan Yingchuanbao overhaul workshop workers.He was joined by a group of pot washers his own age, known collectively as the old boys’ team.Airtight, high temperature oil tank is the main battlefield of their work, to ensure the safety of oil transportation is their bounden responsibility.At present, the train tanker is the main means of transportation of all kinds of oil products in China, and Lanzhou is known as the “cradle” of China’s petrochemical industry, Yingchuanbao washing station as the “gas station” of China petroleum Lanzhou Petrochemical Company to achieve business efficiency, from 1959 began to clean the tank business, more than 60 years,For petrochemical products transport to provide a steady stream of high-quality vehicles.In the evening of February 11, after receiving the dispatch order notice, three empty tank cars were pushed to the tank washing platform.Foreman Wang Chunhong and workers nervous and orderly pre-class preparation, we wear a gas mask, wearing thick cotton work clothes, wearing anti-static gloves, waist high-altitude work protective sling, “fully armed” began the night operation, for the tanker “eliminate thrombosis”.The temperature gauge at this point showed minus 15 degrees Celsius.Pull water pipe, open negative pressure pump, steam, the “old boys” the implementation of the operating procedures orderly, two people a group with a very tacit understanding.Yang jianjun pulled the high-pressure hose to inject water through the entrance. The spray hit the hole cover and splashed everywhere. His clothes and face were immediately smeared with oil.”Summer is cool and comfortable,” said Yang. “In winter, when the biting wind hits me, I feel like I’m digging into my bones.”After about 40 minutes, the washing tank enters the steam heating process.Opening the valve, high-pressure steam — up to 260 degrees Celsius — rushed down the pipe into the tanker, spraying hot steam in Yang’s face under the pressure. It was like entering a “sauna room.”Steam heating is called “sauna” because high-pressure steam can fully dissolve residual impurities in the tank, making it easier to clean.After 40 to 50 minutes of heating, they ventilate the tank with a special blower for 30 to 50 minutes to remove flammable gases.They then have to test the flammable gas content to make sure it is acceptable before entering the tank for cleaning.When the top of the tank was opened, the temperature meter showed that the temperature inside the tank was 79 degrees Celsius. After a little cooling, Wang chunhong and her workmate Shi Xiaobing entered the tank together.There are residual crude oil, heavy oil, methanol, asphalt and other chemical dangerous goods in the tank truck. The task of Wang Chunhong and her workmates is to clean the residual chemical media inside the tank truck before maintenance, so as to do early safety work for maintenance.Shi Xiaobing took a flashlight in one hand, a copper pick, a long-handled brush and other tools to clean the residual sludge in the tank.Pot washers describe the job as removing “blood clots” and making sure the tank is clean and safe to fill.Because the cleaning operation is carried out in a high temperature and closed space with less oxygen content, in order to ensure safety, the tank washer has to come out of the tank every 15 minutes to breathe air.Normally, it takes about 2.5 to 3 hours to clean a tanker, but if there is a large amount of coal tar in the truck, it will need to be manually washed repeatedly to thoroughly clean up the residual oil residue and wood rust.After each assignment, Yang jianjun said, his whole body is like a sauna, so wet that “I can wring water.”Once the tank is cleaned, they test the gas again to make sure it reaches the right readings.”The work is hard and arduous, but through our own efforts, we feel happy to see clean tanker trucks filled with fuel safely arrive in all parts of the country. The pain and hardship are all worth it.”Wang chunhong said.Material: Gansu reporter station of People’s Railway Newspaper Co., LTD.
