Advantages of Straight Seam Welded Pipe
Low production cost
The production cost of straight seam welded pipe is relatively low. Compared with other pipes, the production process is simple, the production efficiency is high, and the production cost is low.
High strength
The strength of straight seam welded pipe is relatively high. This is because the welds of straight seam welded pipe are welded along the length of the pipe, and this welding method can make the strength of the pipe more uniform.
High dimensional accuracy
The dimensional accuracy of straight seam welded pipe is relatively high. During the production process, the size can be adjusted according to the needs, so as to ensure the dimensional accuracy of the pipe.
A wide range of applications
The application range of straight seam welded pipe is very wide. It can be used to convey various liquids, gases and solid materials, such as water, oil, gas, powder, etc. At the same time, it can also be used in construction, machinery, automobiles, ships and other fields.
Easy to process and install
Straight seam welded pipe is easy to process and install. In the production process, cutting, bending, punching and other processing can be carried out according to the needs, so as to meet different usage needs.
Environmental protection and energy saving
The production process of straight seam welded pipe is relatively environmentally friendly and energy-saving, because its production process does not require a lot of energy and resources, and does not generate a lot of waste water, waste gas and waste residue.

One of the main applications of straight seam welded pipes is the construction industry. These pipes are an important part of the construction of high-rise buildings, bridges, and other types of infrastructure. Straight seam welded pipes are usually used to transport natural gas, oil, water and other fluids.
Another important application of straight seam welded pipes is in cargo transportation. They are used in the manufacture of trucks, railroads, ships and pipelines, among other things. Straight seam welded pipes are also widely used in the manufacturing industry. They are used in the production of various types of machinery.
The steel coil is uncoiled and passed through a series of shearing and leveling machines to form a flat and straight steel strip. The strips are then fed into a welding machine and welded lengthwise to form a continuous seam.
With the high-frequency resistance welding (HFW) process, electrodes and a power source are used to heat and melt the steel at the joint.
The pipeline undergoes a series of testing and inspection processes including pressure testing, ultrasonic testing, visual inspection and magnetic particle inspection. Cut and coat the straight seam welded pipe to prevent corrosion.
Fundamentally speaking, spiral steel pipe or straight seam welded pipe is a kind of welded tube. Because of their superior performance, these two steel pipes are widely used in various projects. Of course, because the two production processes are different, in actual there is still a big difference in the use process, which directly leads to a big difference in the use range of the two steel pipes.
Compared with spiral steel pipes, the production process of straight seam welded pipes is much simpler. The production process of straight seam welded pipes is mainly divided into two types, one is high frequency welded straight seam welded pipe, and the other is submerged arc welded straight seam welded pipe. It is precisely because of these characteristics that the production process of the straight seam welded pipe is simple, the production efficiency of the straight seam welded pipe is very high, the cost is low, and the development speed is also very rapid.
Installation Requirements of Straight Seam Welded Pipe
For the installation of straight seam steel pipes, design and position the pipes according to the drawings, prefabricate the pipe racks according to the site conditions, then cut the materials according to the design and site, use a polishing machine to polish the grooves and then weld them.
Use quality requirements: Branch pipes should not be welded at the weld, and welds at bends should be avoided. The deviation per meter for vertical installation should be less than 3 mm, and the deviation per meter for horizontal installation should be less than 1 mm. The weld should be straight and full. There is no burn-through and cracks on the weld surface.
