I, product use
Used for various pumping oil, gas and water Wells played sand protection, prolong production cycle pump function, improve productivity, wastewater treatment and chemical branch are available.
II, structure characteristics
Around the welding type stainless steel sieve tube is "V" type by large openings, 1Cr18Ni9Ti forming welded wire around the system, it is through control round wire the gaps between the role play sand control, around the welding stainless steel sieve tube with other types of sand control tube comparison, specific have higher flow capacity, high strength, corrosion resistance is out of shape not easily long life, safe and reliable, obvious effect, low cost, is a bit oil industry in the most effective sand control tools.
