Iron Pipes

〣Introduction to carbon structural Steel Q195 This kind of steel is generally smelted by converter or open furnace, and its main raw material is molten iron and scrap steel. The content of sulfur and phosphorus in steel is higher than that of high-quality carbon structural steel, with sulfur ≤0.050% and phosphorus ≤0.045%. The content of other alloying elements, such as chromium, nickel and copper, brought into the steel by the raw material generally does not exceed 0.30%.International standard ISO: HR2(σs195). 〣Production technology Q195 steel pipe is carbon structural steel, production process: arc welded pipe resistance welded pipe gas welded pipe furnace welded pipe. Q195 weld pipe to transfer low pressure fluid. General welding pipe Q195A, Q215A, Q235A steel manufacturing. It can also be made of other mild steels which are easy to weld. Water pressure, bending, flattening and other experiments should be carried out on the steel pipe, which has certain requirements on the surface quality. Usually, the delivery length is 4-10m, and the delivery length is usually fixed (or multiple) feet. The specification of the welded pipe is expressed by the nominal diameter (mm or inch). The nominal diameter is different from the actual diameter. The welded pipe has two kinds of ordinary steel pipe and thickened steel pipe according to the specified wall thickness, and the steel pipe has two kinds of thread and no thread according to the form of the pipe end. Q195 is a carbon structural steel. Yield strength 195MPA. Lower strength than Q235. The price is cheaper. Used in construction, structure, motorcycle price, etc. The ASTM brand is Gr.B(σs185). σs185 is a yield strength of 185MPa.

Slotted/perforated pipes and tubes are common casing layer for pipe-core wire wrapped well screens. The perforated casing tube has round holes uniformly distributed for smooth flow of the liquid. It is actually a supporting pipe for sand control system in drilling oil or water wells. The metals are mostly stainless or mild steel. How it Works: Perforated pipe or punched tubing is used as connection support. It links the wellbore and the producing formation through punched holes in the casing and the cement sheath that surrounds it. The size and distribution of perforated hoses pose a direct impact on well productivity. Features: Available in J55 or N80. J55 and N80 have high strength and less potentiality of deformation. Punched hoses are smooth and clear without burrs. Easy installation. Overall preservative treatment creates a dense protective layer over the surface of the pipe and improves corrosive resistance. Six types of punched hoses are available for specific application. Two types of hoses distribution are manufactured.

Victall is a manufacturer of perforated, spiral wound tubes used for sand control assemblies in oil field down-hole operations & other applications including water treatment, food processing, nuclear energy & pulp & paper. Sand Control Assemblies inclues: Perforated Tubing Perforated Tubing Filters Spiral Welded Metal Tubing Perforated metal tubes are available in diameter up to 6 in. & lengths up to 30 in. in different metals including carbon steel, stainless steel & aluminum in different thicknesses. We manufacture standard & custom perforated metal tubes. Materials handled include stainless steel & carbon steel, aluminum, brass, bronze, phosphorbronze and other metal alloys. Perforated tubing is available in OD up to 3 in., wall thickness from 0.024 in. to 0.118 in. & tube lengths up to 27.5. Popular sizes: Steel tube OD - 30mm wall thickness 0.5mm length of tube will be 91mm and 136mm lengths. Holes for the perforated tube 1 - 2mm holes.

Perforated liner is a sand control screen widely used in the horizontal completion wells of SAGD and other thermal heavy oil recovery. It is made of stainless steel or galvanized steel pipes slotted with single, double line or staggered patterns. This metal tubing has excellent properties in withstanding installation loads and operation loads make it the premier choice for SAGD. The perforating of liners are done with laser cutting process without contact operation. This process can effectively avoid undesirable factors which will cause the deformation of the base pipe. Laser cutting process uses windows interface for easy operation and accurate calculation. Perforated liner geometry consists of stamped length, stamped width, line density and perforating distribution. All these parameters can be bespoken to achieve the required open area. For example, multiple staggered pattern or gang pattern significantly increases the open area compared with single cut pattern.

Round opening perforated sheet metal is the most widely used for making of perforated pipes/tubes. The sheet metal is punched by a die to get its round opening. The shape of the hole is determined by the shape of the die. For perforating a round hole pattern, the die is pre-made into circular shape. Then the sheets or plates are welded together to form a cylinder or tube. Round hole opening has two patterns of staggered centers. 60°Degree Staggered Centers round hole are the most popular of all pattern types because of their inherent strength, their multitude of varied open areas ,and their attractive appearance, An alternate to the standard patterns is 45°degree staggered centers .Straight center round hole patterns are available in various sizes and open areas, but they are the weakest of the round hole pattern. The die’s diameter can vary from approximately twice the thickness of the material being punched to over two inches. Specifications: The thickness of metal sheet:0.1-12mm Hole types : round Tube types: round, or square Uses: Round hole perforated tubes are used for decorating, cage ventilation, antiskid. At the same time, the different metal mesh can be as the guard of central heating, air conditioning equipment, different sorts of chassis and machines. Another important use is filtration. For instance, filter, filter pipe, water and gas treatment equipment. The surface of the tube is plain, clean and no furring.

Stainless steel corrugated pipe is installed in the liquid conveying system as a kind of flexible pressure-resistant pipe to compensate for the mutual displacement of the pipes or the connecting ends of machines and equipment, absorb vibration energy, and can play the role of vibration reduction and noise reduction. It has good flexibility and light weight. , Corrosion resistance, fatigue resistance, high and low temperature resistance and many other features.
