The industrial gas pipe is a special pipe for conveying flammable gas. It is a metal gas pipe hose to replace the traditional buckle rubber hose, which can solve the problem that the rubber pipe is easy to fall off, easy to aging, easy to bite, and has a short service life. The steel pipe for the gas line has the characteristics of convenient installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, and can be bent without deformation or gas barrier. The surface soft protective layer material is safer, easier to clean. The stainless steel threaded metal hose has a service life of 8 years. PE gas pipe in China's municipal pipe market, plastic pipe is developing steadily, PE gas pipe, PP-R gas pipe, UPVC gas pipe have a place, the strong development momentum of PE pipe is the most eye-catching, its use is also very Extensive. The most common gas piping is black steel. Galvanized steel, copper, brass, or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper. In other areas, the use of copper is widespread. Before you decide to buy steel gas pipes from gas pipe manufacturers, you should consider the right material for the pipes. Steel piping typically is black with malleable iron or steel fittings. Galvanized steel is used in some areas as well, so you can also find galvanized pipe for gas line in Tianchuang.

Fire fighting pipe is a kind of normal carbon steel pipe for conveying water, gas and other fire suppression agents. It's usually in red. But the exterior of the light-wall pipes is galvanized silvery. The installation of a red steel pipe is only to be used as a wet sprinkler system. Dry and wet pipe sprinkler systems (including pre-action pipe sprinkler systems) are allowed to install galvanized pipes. Since the installation of the first fire protection system, black steel has been the traditional leader of the fire sprinkler pipe market because of its strength, durability, and extreme resistance to heat exhibited. With a melting point between a whopping 2,600°F and 2,800°F (1,427°C and 1,538°C), steel pipe can withstand the heat of burning buildings, it even can keep water flowing over a fire. Steel Pipe for Fire Protection Systems Fire suppression pipes are easy to form, bend, and fabricate, which can be manufactured in various sizes, shapes and configurations. Steel pipe has been the main material of sprinkler piping systems for a long time. Steel is considered strong, durable and resistant to fire. With a melting point of about 2,700°F, the fire service pipe can withstand the heat of a burning building. Steel fire sprinkler pipe can be connected by screw thread, welded connection, rolling connection and groove cutting connection. Threading is only allowed for Schedule 40 or heavier pipe. However, if a lighter wall pipe is listed by a specialized thread testing laboratory, NFPA 13 (National Fire Protection Association) will allow the lighter wall pipe threads. Fire Fighting Pipe's National Standard GB/T5135.20-2010 standard GB/T17219-1998 standard CJ/T120-2008 standard.

ERW pipe means electric resistance welded pipe, and it is a resistance welding by 10-500 kHz of high-frequency current. The raw material of the ERW steel pipe is hot rolled steel coil made of steel billet, and the usual material is Q195, Q215, Q235, Q355 in China ERW pipe grade, which are same material with S195, S235, S355 in Europe, and SS400 in Japan. ERW steel pipe suppliers will cut the steel coil into strips first, the strip width is according to the perimeter of the pipes and then shaped by mold, welding, cutting, straightening, inspecting, end smoothing, packing, and final storage or dispatch. The pipes are used widely in construction and infrastructure, such as scaffolding, water and gas delivery, fire control system, oil and heat delivery, and other low-pressure liquid delivery. Generally, the length of pipes produced by the erw steel pipes manufacturers is 6m, which can be determined according to the requirements of the buyer.

Packing: Bare packing/bundle packing/crate packing/wooden protection at both sides of tubes Transportation: By 20/40FT containers or by bulk vessels as per condition ERW Steel Pipe's Advantages: ERW pipe means "high-frequency resistance welded steel pipe", which is different from ordinary welded pipe welding process. The weld is formed by melting the base material of the steel strip body, and its mechanical strength is better than that of general welded pipe. ERW welded pipe has the characteristics of high production efficiency, low cost, material saving, and easy automation. Therefore, it is widely used in aviation, aerospace, energy, electronics, automobile, light industry and other industrial sectors, and it is one of the important welding processes.

The steel pipes for construction (building pipes) can be divided into seamless steel pipes and seamed steel pipes according to seamless seams. Spiral steel pipes are divided into spiral steel pipes and straight seam steel pipes according to the weld seams. They are widely used in construction piling, structure, steel structure, load-bearing and drainage. The materials are mainly carbon steel, stainless steel and alloy steel. Among them, the application of carbon steel is the most common, and the main production base is in Cangzhou, Hebei. According to the customer's requirements, the length of the steel pipe can be fixed, or the ruler can be used. The price of the fixed ruler is more expensive than the loose ruler per ton.

ASTM A795 Steel Pipe ASTM A795 is the standard for black and hot-dipped zinc-coated (galvanized) and welded steel pipes designed for fire protection specification by the American Society for Testing and Materials. This type of piping is suitable for mechanical and pressure applications as well as for the general use of steam, water, air and gas piping. ASTM A795 Steel Pipe's Diameter Although the pipe can be bent, it is not at ambient temperature, because the inside diameter of the elbow is less than 12 times the outside diameter of the elbow. The steel shall require for the specified chemical composition. Every section of the pipe should be hydraulically tested and no leakage through the wall. As a choice of the hydrostatic test, each pipe shall be tested by a non- destructive electrical method if accepted by the buyer. Finally, according to the requirements of resistance welded pipe and furnace welded pipe, the pipe is compressed.

ASTM A500 Steel Pipe ASTM A500 is the standard specification for circular, square, and rectangular tubes of cold-formed welded and seamless carbon steel structures. ASTM A500 is the most common specification for Hollow Structural Sections in North America. The correct way to specify the circular HSS section is to represent the outer diameter in decimal inches to three decimal places (i.e., 5.563 x 0.250) according to the nominal wall thickness. Why A500 Steel Pipe? Since ASTM A500 is a structural specification, circular high-speed steel produced according to this specification is suitable for structural applications and general construction purposes. The specified yield strength of A500 Grade C (the most commonly available grade) is 46 ksi. The specified yield strength of A53 Grade B is 35 ksi. Yield strength increased by more than 30%. Therefore, the strength to weight ratio of A500 circular HSS is greater than that of A53 pipe. So, if you do the job with round HSS, you need less steel, by weight, to do the job—the lighter it is, the lower the cost. The tolerances of A500 are tighter than those of A53, so the HSS of the A500 circle has higher quality and less variability. Round HSS has a superior surface finish and is not as lacquered as normal A53 tubes. Since this lacquer coating needs to be removed from the A53 pipe to accommodate welding and painting, so this can save money and time. ASTM A500 Steel Pipe Applications All steel structures have their pros and cons including structural supports, building columns, highway signs, oil field services and communication towers, to name a few. But ultimately ASTM A500 is a better choice when you need a round profile. We encourage architects, fabricators, structural engineers and contractors to read up on ASTM A500 and visit The Steel Tube Institute's website because it offers a wide variety of technical publications, load tables and design aids.
