Particle size measurement is usually realized by particle size analyzer. The traditional methods mainly include screening method, microscope method etc.
Laser Particle Sizer is the most widely used particle size measuring instrument at present, especially the static light scattering diffraction particle sizer, which mainly measures the light energy distribution when the laser passes through the particles, and then deduces the particle size distribution by inverse calculation. It has the advantages of wide particle size measurement range, wide application range, good reproducibility, fast measurement speed, convenient operation and online measurement. It can obtain a variety of particle size data, such as volume average particle size, particle size curve, interval particle size distribution and cumulative particle size distribution, which are widely used.

What is the Difference Between 316 and 316L

As we all know, 316L is a stainless steel grade. AISI 316L is the corresponding American grade, and SUS 316L is the corresponding Japanese grade. The Chinese standard brand is 022cr17ni12mo2 (new standard), and the old brand is 00Cr17Ni14Mo2, which indicates that it mainly contains Cr, Ni and Mo. The number indicates the approximate percentage. Let's first look at the chemical composition of 316 and 316L.


We can see that the carbon content of 316L is lower and has better corrosion resistance.
1 welding method of stainless steel pipes
Because most of the stainless steel pipes are of different sizes, according to the welding characteristics of stainless steel, the heat input is minimized, so manual arc welding and argon arc welding are adopted.
For pipe diameter greater than 159 mm, argon arc welding shall be used for bottom drilling and manual arc welding cover. All argon arc welding with diameter less than 159mm.

2 welding materials
Austenitic stainless steel is a special performance steel. In order to meet the same performance of the joint, the welding material should be selected according to the principle of "equal composition". At the same time, h00cr19ni12mo2 welding wire for argon arc welding and chso22 welding rod for manual arc welding should be selected as the filler material to enhance the resistance to hot crack and intergranular corrosion and make a small amount of ferrite appear in the joint.
3 welding parameters
The outstanding characteristic of austenitic stainless steel is sensitive to overheat, so small current and fast welding are adopted. The interlayer temperature should be strictly controlled during multi-layer welding, so that the interlayer temperature is less than 60 ℃.
4 groove form and assembly positioning welding
The V-shaped groove is used as the groove form. Due to the small welding current and small pe*******on, the blunt edge of the groove is smaller than that of carbon steel, about 0-0.5mm, and the groove angle is larger than that of carbon steel, about 65 °- seven hundred °。
Due to the large thermal expansion coefficient of stainless steel, the welding stress is large during welding, so the strict positioning welding is required. For D ≤ Φ 89mm pipe is positioned by two points, D= Φ 89- Φ Three point positioning is used for 219mm, and four point positioning is used for D ≥ 219mm; The length of tack weld is 6-8mm.

Manufacturing Method Of Iron Powder
In this article, we will learn how to make iron powder. Powder manufacturing methods are usually divided into two categories, namely physical-chemical method and mechanical crushing method. Reduction method, atomization method and electrolysis method are widely used in industry. The preparation method and general characteristics of iron powder are also discussed.
Iron ore reduction method, general characteristics: irregular powder particles, low bulk density, high impurity content, slightly poor compressibility. Main uses: structural parts, welding rod, metal cutting. cheapness.
Iron scale reduction method, general characteristics: irregular powder particles, medium bulk density, high purity, good compressibility, high compactness, good sinterability. Main uses: structural parts, welding rod, metal cutting. cheapness.
Atomization method, general characteristics: powder particles close to spherical, high bulk density, good fluidity, high compact strength. Main uses: high density structural parts, powder forging parts, filters, welding rods. The price is more expensive.
Electrolysis method, general characteristics: the powder particles are dendritic or flaky. It has the advantages of high density, high purity and good compression. Main application: high density structural parts.
Carbonyl method, general characteristics: spherical powder particles, very fine, high purity. Main uses: electronic materials. It's expensive.
