Spiral Perforated Tubes

Spiral seam Spiral technology: benefits Although spiral weld is a more challenging process compared to longitudinal welded, the following advantages are exhibited: More flexibility over a wide range of sizes, thus able to produce at unconventional diameters and tolerances. An increased safety factor due to the internal stress on the spiral weld being less than on a longitudinal weld The use of strip instead of plate permits more uniform wall thickness due to the close dimensional tolerance Due to the continuous process, any length of tube can be produced as opposed to the length limitation of a plate mill. The tube is straighter and rounder than one produced on a longitudinal mill. Spiral weld provides greater strength and rigidity at reduced wall thicknesses. Wooden box

No.1 Introduction: Galvanized Spiral Gas Drainage Tube is adopted international advanced production equipments by our company. Its galvanized with the inner and outside. It includes jointing spiral tube and without-jointing spiral tube. It has the following advantages: smooth inner wall, little resistance, light in weight, corrosion-proof, long service life, low cost, etc, it is the ideal equipment of Gas Drainage Tube in coal mines. The jointing spiral tube is adopted cast steel flange connection, the automatic welding technics for the connection of tube body and flange. Comparing with riveting technics, the technics avoids the second scathe to the tube body, and also with better capability of gasproof. Due to the techniques of riveting with the misdistribution of joints, and the improper installation is easily leading to rips of tube. Aiming to the point, our company meets track with international technics and adopts integrated welding technics to avoid the existence problems of riveting. No.2 Usage: The product can be widely used in mine ventilation, gas drainage, and road and bridge construction, housing structure, discharging lampblack, draining contamination and basic equipment installation, etc. No.3 Product Advantages: ú¿1ú¬. Comparing with the traditional glass steel gas drainage tube and steel gas drainage tube, the mine-use galvanized spiral gas drainage tube has the following advantages: 1. Light of the pipeline in weight and easy to convey. 2. High-grade galvanized steel belts used and there is no use to consider of the burning blockage and electrostatic-proof problems. 3. Widely applicable diameter range from 80mm to 1600mm. 4. Spiral hinge mouth increases the loading power and pressure from the pipeline. 5. Inner wall of tube is smooth, little resistance and good circulation. 6. Galvanization prolongs service life. 7. Adopting cast steel flange connection, easily assembly and disassembly, with good interchangeability. (2) Advantages of Galvanized Spiral Tube for Air-conditioner: 1. Good match with other products and high standardization. 2. Good capability of airproof. 3. Low wastage of aeration. 4. Convenient project checking. 5. Pressure resistance is better than ordinary tube and rectangle tube. 6. Saving material. 7. Low cost installation. 8. Elegance of integrated overall arrangement. 9. Convenient daily maintenance.

Perforated steel tubing is a type of steel pipe that has holes or perforations evenly distributed along its length. These holes can serve various purposes depending on how the tubing will be used. The process of creating these holes involves techniques like punching, drilling, or laser cutting. This type of tubing finds applications in industries such as construction, automotive, architecture, and more. The holes can serve functions such as filtration, noise reduction, heat dissipation, structural support, and aesthetic design. The choice of materials, coatings, hole sizes, and patterns can be tailored to the specific needs of the project or application.

Spiral wound finned tubes or crimped finned tubes spiral wound on the base tube, without welding, but spot welding at the end. Material of spiral wound finned tube or crimped finned tube: the finned strip can be copper, carbon steel, stainless steel, non-ferrous metal tube and fin, or it can be root welded or completely welded. Spiral crimped stainless steel finned tube. Spiral tension wound finned tubes for air coolers. Due to the high corrosion resistance of stainless steel, when the environment has certain corrosivity or cleanliness, such as climate industry, heating, drying and cooling, stainless steel crimped fin tubes can be widely used. Usually used for finned tube heat exchangers. The maximum working temperature is 180 â??. Compared with L-shaped finned tubes, spiral wound finned tubes or crimped finned tubes provide higher air side turbulence and heat transfer due to fins curling. Material standard of crimped fin tube: both base tube and fin can be carbon steel and stainless steel Carbon steel: A179, A192, SA210 Gr A1/C, A106 Gr B Stainless steel: TP304/TP304L, TP316/TP316L

Round hole stainless Perforated Metal Tube Perforated Metal, Metal Tube, Advantages of Perforated Metal Tube Perforated metal tubes are popularly used in filter products as support tubing and sometimes it is used directly as filter tube and cylinder for certain industries. We can manufacture perforated tube solutions with high tolerances and straight or flared ends to allow for unrestricted flow, facilitating flow pressure and temperature measurements. Construction of our tubes can include spiral or longitudinal welded seams or lock seams and you can choose any combinations from a selection of hole sizes and patterns. Micron opening perforated metal tubes are used as filters or screens itself in the screening of coal, gravel and ore; in the shifting and separation of food products, medical material, fine chemicals and oil. It is made of quality stainless steel or carbon steel sheets, perforated filter tubes and cylinders can be made spiral welded or butt welded in a wide range of sizes.
