| In 1993, Together with Bohai marine co***ny jointly developed, instead of foreign high-pressure refractory pipeline, and in the offshore oil instead of foreign products. In 1996 ,at the Lake Jingpo meeting, to achieve the promotion of land oil hose. At the meeting of the 1998 blowout drill in Guanghan, our co***ny 's Refractory pipeline was tested by fire. In 2000, the products of the Great Wall drilling (GW) and China Petroleum Technology Development co***ny (CPTDC) were exported to Turkmenistan, Iran, Venezuela, Indonesia and other countries. 2009 in Sichuan, Guanghan, China's oil blowout emergency contingency plans, the fire line and nozzle line through the test of natural gas combustion. In January 10, 2013, the high-pressure refractory flexible throttling well pipe successfully passed the test of the Southwest Institute of the United States, and the comprehensive performance of the product was fully affirmed and recognized. As a professional manufacturer of high pressure fire hose for oil field, the success of this test provides reliable theoretical and data support for our co***ny's products in the domestic and international market. The products include three parts: deformation and hydrostatic pressure test, normal temperature and low temperature bending test and fire resistance test.
