无锡方管市场价格与上周同期跌50元。受中美贸易战升级影响，无锡地区方管价格下调，出货量维持在1500吨左右，部分有出口贸易的贸易商出口业务受到一定程度的影响。截至5月10日，山东108*4.5报价4600元；兴亚38*3.5报价5600；华润108*4.5报价5050元；天淮426*11报价5300元。无锡方管价格较上周跌50元。

The market price of Wuxi Fangguan fell 50 yuan compared with the same period last week. Affected by the escalation of Sino-US trade war, Wuxi's local control price has been lowered, and the shipment volume has been maintained at about 1500 tons. Some traders with export trade have been affected to a certain extent in their export business. As of May 10, Shandong 108*4.5 quoted 4600 yuan; Xingya 38*3.5 quoted 5600 yuan; China Resources 108*4.5 quoted 5050 yuan; Tianhuai 426*11 quoted 5300 yuan. The price of Wuxi Fangguan is 50 yuan lower than last week. 本周管厂、管坯价格双双下跌。无锡地区大户贸易商有固定客户，其出货量还维持在1500吨左右的水平，受贸易战影响不大，小户贸易商没有固定资源，出货量偏差，心态偏谨慎，对后市不看好，贸易商基本以走量为主，短期内无锡方管市场偏弱运行。

Pipe factory and billet prices both fell this week. Large traders in Wuxi have fixed customers and their shipments remain at the level of about 1500 tons, which is not affected by the trade war. Small traders have no fixed resources, deviations in shipments, a cautious attitude, and are not optimistic about the future market. Traders basically take the lead in volume. In the short run, Wuxi Fangguan market is weak.
