1. Check whether the specifications of the welding wire and flux are correct according to the welding process regulations to prevent the wrong use of welding wire and flux and cause welding accidents. 2. Supervise the welding environment. When the welding environment is not good (the temperature

An anti-corrosion spiral steel pipe is an anti-corrosion treatment for a spiral steel pipe. The main anti-corrosion method is the polyurethane anti-corrosion spiral pipe. After the pre-treatment such as rust removal of the steel pipe, it is covered with a polyethylene jacket. Filled with foam, the t

⑴ Weak welding, desoldering, cold folding in the steel pipe; Reason: The output power and pressure are too small. Solution: 1 adjust the power; 2 adjust the extrusion force.   ⑵ There are ripples on both sides of the weld in the steel pipe; Reason: The op

Due to the corrosion of steel pipelines and equipment, production enterprises have stopped production and the quality of products has deteriorated. It affects the supply of gas, heating steam, or hot water, and brings many difficulties in people's lives. Leakage of buried pipelines and pipeli

The uniformity of the wall of thick-walled straight-seam steel pipes will directly affect the later processing of parts. The wall of thick-walled straight-seam steel pipes cannot be controlled, which means that the overall steel pipe cannot be strictly controlled. Small and medium-sized steel, wire

The outer surface of the stainless steel elbow is made of high-density polyethylene material, which has extremely high mechanical strength and excellent corrosion resistance. It can protect the elbow from damage caused by external factors during transportation, installation, and use.

The stainless steel pipe socket argon arc welding construction method has the following characteristics: 1. The welding process does not require welding materials (replaced by expanded pipe edges). The steel pipe is inserted into the pipe fitting socket, and the end of the socket is welded in a circle using gas tungsten arc welding (GTAW) to melt the pipe into one body. Not only can The weld seam and the pipe be integrated and have the same color, and can save welding accessories and increase the welding speed.

Austenitic stainless steel is softened by solid solution treatment. Generally, the stainless steel pipe is heated to about 950~1150℃, and kept for some time, so that the carbides and various alloying elements are fully and evenly dissolved in the austenite, and then quickly quenched to cool. , carbo

Pipes are classified into two groups: seamless pipes and welded pipes, based on the manufacturing method. Seamless pipes are formed in one step during rolling, but bent pipes require a welding process after rolling. Welded pipes can be classified into two types due to the shape of the joint: spiral welding and straight welding.

Carbon steel, Alloyed Steels, Stainless Steel, Galvanized Steel

Pipes are used in construction, transportation, and manufacturing. Different materials, design features, and manufacturing methods for steel pipes have evolved and vary depending on the application.

All stainless steels must contain at least 10% chromium. The strength and durability of metal. Mainly due to the chromium content. It also includes varying amounts of carbon, manganese, and silicon. In some types, nickel and molybdenum are added depending on their intended use. Indeed, the following advantages apply to stainless steel.

Electric Resistance Welding Process (ERW), Electric Fusion Welding Process (EFW), Submerged Arc Welding Process (SAW)

Stainless steel is an alloy of iron containing at least 10.5% chromium. This chromium allows the formation of a very thin oxide layer on the metal surface, also known as the "passive layer" and gives stainless steel its distinctive shine.

A106 and A153 are the most commonly used steel tubes in industry. Both tubes are very similar in appearance. However, there are some basic differences in specifications and quality. A basic understanding of seamless and welded pipe is required to purchase the right quality pipe. Talk to pipe pile suppliers for details.

As production processes have changed and become more complicated, the choice of steel buyers has increased to meet many specific requirements in various industries.

With the rapid development of construction work in recent days, the new manufacturing methods are also developing accordingly. Steel pipes are essential for the work on the construction site.
