First, has excellent, long-lasting thermal insulation The lowest possible thermal conductivity is the goal pursued by all insulation materials. The extruded board is mainly made of polystyrene, and the polystyrene is originally an excellent low-heat-conducting material, which is supplemented by extrusion molding. The tight honeycomb structure is more effective in preventing heat conduction, and the heat-concentrating plate is thermally conductive. The coefficient is 0.028/mk, which has the characteristics of high thermal resistance and low linear expansion ratio. The thermal conductivity is much lower than other insulation materials. Such as EPS board, foamed polyurethane, thermal insulation mortar, perlite and so on. Second, superior water and moisture resistance The extruded board has a tight closed cell structure, the polystyrene molecular structure itself does not absorb water, and the front and back sides of the plate have no gaps, so the water absorption rate is extremely low, and the moisture resistance and the penetration resistance are excellent. Third, anti-corrosion, durability The general rigid foam insulation material is prone to aging after several years of use, which in turn causes water absorption to cause performance degradation. The extruded board can maintain its excellent performance due to its excellent anti-corrosion, anti-aging, heat preservation and high water vapor pressure, and its service life can reach 30-40 years. species: According to the compressive strength p of the product and the skin, it is divided into the following ten categories: a) X150-p>-150 kPa with skin; b) X200-p>200 kPa with skin; c X250-p>250 ​​kPa with a skin; d) X300-p>300 kPa with skin; e) X350-p>350 kPa with skin; f) X400-p>400 kPa with skin; g) X450-p>450 kPa with skin; h) X500-p>500 kPa with skin; 0 W200-p>200 kPa without skin; j) W300--p>300 kPa without skin. Other surface structure products, agreed by the supplier and the buyer According to the product edge structure, it is divided into the following four types: 1, SS flat head products 2, Si type products (lap) 3, TG type products (birch trough) 4, RC type products (rain trough) Elevators, slips, wellhead tools for oil drilling Casing elevator slips, tubing elevator slips, sucker rod elevator slips, drill collar elevator slips, drill pipe elevator slips. The hydraulic elevator is a split type elevator. Taper drill pipe, drill collar, casing and tubing can be suspended by replacing the inner lining. The hydraulic control system is more convenient to operate, which can effectively reduce the labor intensity of workers and improve work efficiency. Can realize remote control, safe and reliable to use. The elevator is designed and manufactured according to API Spec 8C "Drilling and Oil Production Lifting Equipment". Slips are designed and manufactured according to API Spec 7K requirements The company has developed a wide range of oil drilling and production wellhead mechanized tools, complete specifications, various slips, elevators, and more than 100 series of product structure specifications, and sales cover major oil fields across the country, as well as Europe, the Middle East, Central Asia, Southeast Asia and other regions.
