    • XINCHENG XCG20080531 spiral wound gasket

      Spiral Wound Gasket is the ideal gasket in the semi-metallic category. A narrow strip of V-shap metal hoop is spirally wound under tension with a filler cushion between the lamination of the metal and is spot-welded at both ends. This unique construction of a spring-like metal and soft filler provides gasket excellent characteristics:Resistance to high temperature and high pressures.Great resilience which allows the gasket to adjust automatically to change in operating conditions, such as pressure and thermal shocks, vibrations etc.Excellent sealability is maintained with comparatively small gasket area.Good tolerance for flange surface finish irregularities.Can be designed to any dimensions economically in circular or moderately noncircular shape. Available in a variety of hoop metals and filler materials to satisfy specific operating conditions.Structure:Type Cross section Hoop material Filler material Inner, Outer ring material Normal Thickness Gaskets Rings Basic type CS,304(L)SS,316(L)SS,321SS,347LSS,Monel,Titanium,Inconel,Hastelloy B/C, Incoloy,etc.Asbestos CS,304(L)SS,316(L)SS,321SS,347LSS,Monel,Titanium, Inconel,Hastelloy B/C Incoloy,etc.2.5(.0624)3.2(.125)4.5(.175)6.4(.250)7.25(.285) 234 With inner ring Non-asbestos With outer ring Flexible graphite With inner &out ring PTFE CeramicAvailable Sizes: Item DIN (mm)ANSI B16.5 BS1560 (mm)Mss sp-44API 605TolerancesInner ring I.D.Gasket I.D.≤600≤24"≥26" & ≤34"±0.5>600 & ≤800>24" & ≤ 34"≥36" & ≤60"±0.9>800 & ≤1600>34" & ≤60" -±1.3>1600>60" -±1.6Gasket O.D.≤600≤24"≥24"±0.9>600 & ≤1600>24" & ≤60">24" & ≤60"±1.8>1600>60" -±2.2Outer ring O.D - -≥1/2" &≤ 60"±0.9≤600≤24" -0-1.0>600 & ≤1000>24" & ≤34" -0-1.8>1000 & ≤1600>34" & ≤60" -0-2.2Note: We also can produce according to GB4622.2-93,JB4705-92,JB/T4719-92,SH3407-96,HG20610-97,JB/T90-94,ANSI,API,JPI,JIS,DIS,etc.standards or clients request

    • IRISATED sodium hyaluronate food grade

      sodium hyaluronate food grade is produced in highest level during embryonic period of life, gradually decreases after birth. HA content is different among the crowd of the same age. For example, HA content of the premature senility patient is obviously reduced.Topical usage of HA can play the action of water retention and lubrication on the surface of the skin. Its limit is obvious. However, oral HA can increase endogenetic HA by digesting and adsorbing and make skin moist, bright, springy.sodium hyaluronate food grade also plays important role of water retention and lubrication in other tissues and organs, such as joint cavity, blood vessel, heart and brain. Decrease of HA will lead to arthritis, arteriosclerosis, pulse disorder and brain atrophy. Oral HA can restore the normal content of HA, delay apolexis and make the body energetic.At present, sodium hyaluronate food grade is widely applied in health and beauty food in America an Japan. It is great welcomed by the consumers.

    • IRISATED Hyaluronic acid

      Hyaluronic acid (HA) is the pure acid form of hyaluronic acid, which hydroxyl is hydrogen. Hyaluronic acid (HA) likes sodium salt, with strong absorption and viscosity in the water solution. Its stablity in the water solution can be greatly imporved for the low content of metallicion and acidity, meanwhile customers can change it into the congruent salts according to their requirements.Hyaluronic acid plays the same role like Sodium Hyaluronate, which can be widely used in cosmetic, medicine, food and health food.Traditionally, HA is used in cosmetics, but it can be widely used in teh different fields of food, health food, and medicine. Right now it has been expanded to medical grade, food grade, and cosmetic grade. HA plays the same role like Sodium hyalruonate which is also an important material for medicine, food and cosmetic; while Calcium hyaluronate, Zinc hyaluronate are mainly used in food and health food.
