pipe flange

pipe flange

Blind plate flange (blind flange) also known as blind plate, the correct name is called flange cover. Is a flange with no holes in the middle for sealing the pipe plug. There are many types of sealing faces, including plane, convex, concave, tenon, ring joint. One of its functions is to seal the end of the pipe, and the other is to facilitate the removal of sundries in the pipeline during maintenance. As far as sealing effect is concerned, it has the same function as head and pipe cap. But there is no way to remove the head, and the flange blind plate is bolted and easily removed. Flange blind plates are made of carbon steel, alloy steel, stainless steel, plastic, etc.

Weld neck pipe flanges is a flange that connects steel pipe, fittings, etc into flanges through fillet welds to equipment or pipes, just like plate flanges. The weld form is different: the weld form between the flange and the pipe is fillet weld, but the weld form between the flange and the pipe with neck butt welding is the circumferential weld; the material is different: the material of the flange with neck is machined by the ordinary steel plate which meets the requirement of thickness, while the material of the flange with the butt welding with the neck is mostly machined by forging steel; nominal pressure is different: nominal pressure of flange with neck is 0.6-4.0MPa, and nominal pressure of flange with neck butt welding is 1--25MPa grade.

Steel Pipe

LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.The coherence of cutter head and plate clamping system guarantees the invariable parameters during the entire milling process; accordingly it ensures the milling quality and lays a good foundation for the success of subsequent welding. Line Steel pipe: the oil, gas or water extracted from the ground can be transported to the oil and natural gas industrial enterprises through pipeline. The pipe line includes two kinds of seamless and welded pipes. The pipe ends have flat ends, threaded ends and socket ends. The connection ways are end welding, coupling connection, socket connection and so on. 316 stainless steel pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial transmission pipes and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also commonly used to produce all kinds of conventional weapons, barrels, shells, etc. We also have casing in drillingboiler tube supplierspetroleum pipe line.

Alloy Seamless Pipe

Alloy Seamless Pipe

Alloy seamless pipe is mainly used for power plant, nuclear power, high-pressure boiler, high-temperature superheater, reheater and other high-pressure and high-temperature pipes and equipment. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. Seamless steel tube is a long steel with hollow section and no joints around. The steel pipe has a hollow section, which is widely used as a pipeline for conveying fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe is a kind of economical section steel with the same bending and torsional strength. It is widely used in the manufacture of structural parts and mechanical parts, such as oil transportation, stair handrail, bicycle frame and steel scaffold used in construction. Using alloy seamless steel pipe to make ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, Jack sets, etc., which have been widely used in steel pipe manufacturing. Alloy seamless steel pipe is also an indispensable material for all kinds of conventional weapons, and the barrel, barrel, etc. should be made of steel pipe. In addition, when the circular section bears the internal or external radial pressure, the force is relatively uniform. Therefore, most of the alloy seamless steel tubes are round tubes. Aluminum alloys pipe usually use copper, zinc, manganese, silicon, magnesium and other alloy elements, compared with ordinary carbon steel has a lighter and corrosion resistance, but corrosion resistance is not as good as pure aluminum. In a clean, dry environment, the surface of the aluminum alloy forms a protective oxide layer.

Steel Pipe Fittings

Steel Pipe Fittings

Carbon steel fittings,It is the most widely used pipe product. The main materials are q235 20, 35, 45, 16mn. The main products include carbon steel elbows, carbon steel flanges, carbon steel tees, carbon steel tees, carbon steel diameter tubes (size heads), carbon steel caps (tube caps) and so on. The main implementation standards include national standards, U.S. standards, daily standards, etc., and its Chinese standards also include the Ministry of Chemical Industry standards, Sinopec pipe standards, power pipe standards. Steel pipe elbow in the pipeline system, elbow is a pipe fittings to change the direction of the pipeline. Carbon eccentric reducer It is a kind of pipe fitting used in pipe reducing. The commonly used forming process is reducing pressing, expanding pressing or reducing plus expanding pressing, and stamping can also be used for some specifications of reducing pipes. Carbon steel tee is also a kind of pipe fitting, generally there are two kinds.The straight tee pipe fitting is the same diameter at both ends, and the branch pipe with two different diameters is called reducing tee. Carbon steel seamless steel pipe is a kind of long steel. The steel pipe has a hollow section, which is widely used as a pipeline for conveying fluid, such as oil, natural gas, gas, water and some solid materials.  It is an economic section steel, widely used in manufacturing structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction.
