Xinyue support Maldives firefight construction

 2019.11 months,We Xinyue received inquiry from the beautiful island - Maldives customer : galvanized pipe ERW specifications : 1-6 inches, wall thickness :SHC "STD. The customer is a professional to do fire equipment, so the requirement of the pipe is also high, there must be a professional fire UL certification, galvanized requirements up to 500 grams per square meter, special red paint.

In fact, We have supported many fire pipe during recent years . Especially to Australia.our fire pipe are deeply trusted by Australian customers.

Based on the previous sales experience, we also quickly made a set of all-inclusive plan for the customer.

Round tube procurement, galvanized processing, red paint surface shipping to port.

The new customer from the island country really felt the full range of our enthusiastic services, so the order was confirmed within a week, and the payment was arranged in the second week.

The production process of the whole product is strictly in accordance with the fire fighting pipe standards, the product is ERW 1 inch to 6 inch wall thickness shc40.70 micron galvanized thickness, fire fighting special red paint.There is also a UL certificate for the painted content?Less than a month . the pipes are finished . and the Third-party inspection was also passed in one go . Our customer gave us high appreciation .

Trachoma in welded pipe and galvanized pipe

　　Welded pipes and galvanized pipes often bear major tasks such as structural support, fire water supply, etc., which are related to the safety of people's lives and property, and must not be lost. Problems such as trachoma and leakage welding may cause the stress structure of the pipe to change and the pressure bearing capacity to become weak, resulting in bending and fracture of the structural pipe, and accidents such as water leakage and pipe bursting of the water supply pipe. So, why are there problems with trachoma and leakage welding in pipe products? Mainly for the following reasons:

　　1. The strip of production pipe is deformed by collision

　　The welded pipe is also good, and the galvanized pipe is also welded by strip rolling. If the strip is in the process of transportation, the edge receives the collision, the bending is deformed, and the trachoma and the missing welding are easy to occur during the welding. phenomenon. To solve this problem, in addition to avoiding the collision during the transportation of the strip steel, pay attention to the protection of the strip steel, that is, mark the obvious deformation parts before the strip steel machine, and focus on the marked parts after the tube production is completed. Dispose of waste immediately if there is a quality problem.

　　2. Welder jump fire

　　The situation of welder fire jumping is mainly caused by the negligence of the staff and does not occur frequently. However, in the event of a welder flashover, it will inevitably lead to leakage welding.

　　3. Production line replacement production product size specifications

　　When the pipe production line is replaced with the size specification of the production product, the first few pipe products produced are prone to problems of trachoma and leakage welding due to the size specifications of the machine that have not been adapted at the beginning. Manufacturers with better quality control management will directly scrap the several tubes that were just started when the product size specifications were replaced. In order to improve the yield and reduce the production cost, many manufacturers sell such pipes as qualified products. Although the price is cheap, the problems caused by them are infinite.

Identification Of Seamed Steel Pipes And Seamless Steel Pipes

　　The steel pipe is divided into two major categories according to the molding method and the manufacturing method. The seamless steel pipe and the welded pipe (the welded pipe is what you call the seamed steel pipe). Seamless steel tubes can be further divided into hot rolled and cold rolled cold drawn tubes. The welded pipe can be further divided into a lsaw steel pipe and a ssaw steel pipe. The seam here does not mean that there are gaps, but the steel pipe has weld marks. After the treatment, the welder is difficult to see.

　　The two are divided according to the processing form. The seamed steel pipe is generally welded. The seamless steel pipe has two methods of cold drawing and hot drawing. The carbon steel pipe is in terms of material, and the galvanized pipe is the surface of the welded pipe after the production. Galvanized treatment. Popular: the conveyor carrier requires high, such as pressure, environment, maintenance, corrosion, temperature, etc. with seamless steel pipe. For pressure and temperature requirements, there are seam steel pipes, such as domestic water pipes and gas pipes.

　　The easiest way to identify the two is to look at the look. There are seam steel pipes, there will be a welded straight line, or the surface is polished. There is also straightness, uneven thickness, and it can't be tested. Some tubes with seamless steel pipe are annealed to the weld, eliminating the residual stress of the weld, making the weld equivalent to the base metal, and its pressure range is basically equivalent to that of the seamless pipe. However, some seamless steel pipes which are welded or rolled with the jointed steel pipe are mainly small-sized pipes. These pipes are only seamless pipes in terms of shape, and their essence is not very good. It is a pressure test.

The difference between galvanized steel pipe and black steel pipe

    The carrying work of water and gas for residential homes and commercial buildings would be depend on various pipes like seamless steel pipe, ERW steel pipe, galvanized steel pipe as well as black steel pipe. We know that water and gas would be essential for human needs and what's the difference for different pipes? Today, we would have a comparison for galvanized steel pipe and black steel pipe.

    Galvanized pipe: Covered with a zinc material, galvanized steel pipe would be have the character of more resistant to corrosion. At first, galvanized pipe is just used to carry water to homes and commercial buildings. The zinc also prevents the buildup of mineral deposits that can clog the water line. Galvanized pipe is commonly used as scaffolding frames because of its resistance to corrosion.

    Black Steel Pipe: Different from galvanized pipe, black steel pipe is non-coated. The dark color comes from the iron-oxide which is formed on its surface during manufacturing. The purpose of the black steel pipe at begging is to carry propane or natural gas into residential homes and commercial buildings. It is produced without a seam, making it a better pipe to carry gas. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.

    With time goes on, there is no doubt that technology has gained big progress. Thus the usage of each kind of steel pipe would be wide than before, so do for these two kinds of pipes.
