Farmland irrigation pipe network laying: According to national policies on the issue of agriculture, rural areas and farmers, and increasing assistance every year, our company has designed and produced polyethylene (PE) and polyvinyl chloride for water supply. (PVC) pipes and groundwater pressure extraction pipelines for farmland irrigation have been certified for drinking water supervision. Meet and fully meet the national drinking water standards. 2. Mine pipes: Mine pipes have always been one of the company's leading products. They have been put on the market successively. There are mine gas drainage pipes, ventilation pipes, and mine drainage pipes. At this stage, the latest mining connection hoses and mining hole sealers have been launched. The products have gained a good reputation in mining companies. Our company's products have successively obtained qualification certifications such as coal mine safety certification and drinking water standard certification, and the improved product structure has obtained three national patents.

BUSINESS OVERVIEW

Since its establishment, our company has been a stable and rigorous enterprise. The company leaders boldly adjusted the business direction according to market demand, introduced advanced pipeline production and testing equipment, and significantly improved production technology, production capacity and quality monitoring capabilities until 2017 The annual output of polyethylene (PE) pipes has reached 6000 tons, and the annual output of polyvinyl chloride (PVC) pipes has reached 40 million tons.

1) Brief introduction of manufacturer

Our company has been committed to the development and production of mining pipes. It has a history of more than ten years.
