I and basic parameters: Materials: stainless steel 302,304,316,304 L, 316L sieve wire or low carbon steel galvanized wire. Outer diameter: 4 inches, 6 inches, 8 inch, 10 inch, and 12 inches, etc. (20mm 1000mm) - Gap: 0.1 mm - 35mm deviation: + 0.05 mm standard length: 50-6000mm End connections: silk buckle pipe head or direct pipe head Sieve silk specification: 2.2x 3.0 mm, 2.3 * 3.0 mm, 3.0 * 4.6 mm, 3.0 * 5.0 mm, etc Torre bar specification: 3.8 mm / 22 root, 3.8 mm / 32 root, 3.8 mm / 48 root, 3.8 mm / 50 root. Special specifications on request (such as: in liquid, reflexed, etc.). II and features: 1. Sift the cross-section are trapezoid. The width values dimension wedge graphics a 1.3, 1.6, 1.8, 2.0 and 3.0 2.2, 2.5, etc, due to sift the section for trapezoid, so aperture is always within the small, favourable filtering and washing. (against) in liquid 2 the section steel bar, circular wedge, shape, according to the user's different USES, can with screening the multiple collocation. III, the properties of product: 1.the stable structure, high temperature corrosion resistance, mechanical performance is good, long service life, safe and reliable. 2 joints can be made into parallel joints, the common thread joint, taper tooth joints and trapezoidal tooth connectors. 3. Mainly used in oil, gas and water Wells sand control, mud filtering and other more medium can also be used in water treatment, water softening, petroleum products during terminal filtration and chemical acid organic solution of recycling filtering. 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. III, technical parameters 1. Specifications Nominal size 2. Silk around width (gap) coefficient as follows: (units) mm: 0.1 0.15 0.20 0.25 0.30 0.35 0.40 0.45.50 0.75 1.00 1.25 3.
