Improving people's living standards plays an unparalleled role.

Special shaped pipes generally have large moment of inertia and section modulus, and have large bending and torsion resistance which can greatly reduce the structural weight and save steel.

North Vancouver.Stainless steel tubes can be found everywhere in our daily use. I believe many friends are asking why we have so many stainless steel tube products in our life. So here are three characteristics of stainless steel tubes to help you better understand.

They have different characteristics and different working mechanisms, so the effect of the force bellows compensator will be higher than that of the stainless steel plate bellows compensator in many places. And in terms of installation standards, no driving force is subject to cost or can not compare with the previous one!

.The thin-walled stainless steel pipes of ~ have the characteristics of safety, sanitation, environmental protection, economy and applicability in high-quality drinking water systems, hot water systems and water supply systems that put safety and sanitation first. It has been proved by engineering practice at home and abroad that it is a new type of water supply system with good comprehensive performance, energy saving and environmental protection

Stainless steel plate can be cut by three-dimensional five axis laser. The fully automatic infinite rotation structure can realize 316°, Groove cutting. Conventional laser cutting can only complete vertical linear cutting, and the cutting edge of the steel plate forms a right angle with the plane. Numerical control programming of laser cutting machine

During the installation and welding of stainless steel pipe fixed port, it is difficult to ventilate inside, and some sides are easy to be blocked. In this case, water-soluble paper + blocking plate can be used for blocking. That is, the good side that is easy to ventilate shall be blocked with a blocking plate, and the one that is not easy to ventilate and difficult to block the plate

The side shall be sealed with water-soluble paper, and the outside shall be sealed with adhesive cloth.

In this case, 304 stainless steel pipe will not rust. However, if the 304 stainless steel pipe is used or maintained improperly, or the environment is too harsh,North Vancouver17-7ph stainless steel rod, the 304 stainless steel pipe may rust. When we see rust spots on the surface of steel or orange we can quickly confirm this

It has good performance. It does not need to undergo surface treatment such as color plating, but gives full play to the inherent surface properties of stainless steel. It is a kind of steel used in many aspects. It is usually called stainless steel. High alloy steels such as 13 chromium steel and 18-8 chromium nickel steel are representative. From the metallographic point of view, when the oxide film is incomplete and discontinuous due to insufficient or negligent production process, the oxygen in the air directly reacts with some elements in the product, resulting in the appearance of oxidation of the product.

Alloy elements. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self passivation film) on the steel surface, which can prevent further corrosion of the steel substrate. In addition to chromium, common composite

It is well known that the stainless steel plate bellows compensator is actually quite different from the torsion free tube compensator. The root cause of this difference is that

Inspection basis.Brinell hardness is widely used in stainless steel pipe standards. The indentation diameter is often used to express the hardness of the material, which is intuitive and convenient. However, and 304 stainless steel has uniform sparks forming a straight line.

North Vancouver.Iron oxide and spinel can also be oxidized by salt to become loose ferric oxide,North VancouverStainless steel coil wholesale manufacturer, which is easy to be removed during acid pickling. Due to the high temperature, the formed oxide is partially peeled off and settled at the bottom of the furnace in the form of sediment. Alkaline salt melting pretreatment process flow: steam oil removal → Preheating（

High frequency welding high frequency welding: with relatively high power supply, it can achieve high welding speed for steel pipes with different materials, outer diameter and wall thickness. Compared with argon arc welding, it is more than ten times of its high welding speed. Therefore, the consumption of stainless steel tubes for common use has a high consumption rate. Because

In the line, welcome new and old customers to consult Steel pipes are generally classified as follows.
