  SPHCSPHC—& mdash; In the first place, s is the abbreviation of steel, P is the abbreviation of plate, and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.

In addition to stress corrosion resistance, professional stainless steel plate, stainless steel coil stainless steel belt and stainless steel pipe have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Other local corrosion resistance properties are better than ferritic stainless steel.

.Stainless steel pipe can be divided into equal section pipe and variable section pipe according to the profile shape. Variable section pipes include conical pipes, stepped pipes and periodic section pipes.

According to the purpose, it is mainly divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and marine pipe. Calculation formula for weight of stainless steel square tube: (nozzle perimeter 14 - actual thickness) actual thickness is 0.02491, of which 0.02491 is a constant converted from stainless steel density.

.Cold rolled oriented silicon steel strip (sheet) represents: 100 times of DQ + iron loss value (at the frequency of 50Hz, the waveform is sinusoidal, and the magnetic induction peak value is the unit weight iron loss value of 7T) + 100 times of thickness value. Sometimes, G is added after the iron loss value to represent high magnetic induction. For example, dq133 represents cold rolled oriented silicon steel strip (sheet) with iron loss value of 3 and thickness of 0.3mm. Now the new model is 30q133.

Chinese brand cold rolled non oriented silicon steel strip (sheet) means: DW + 100 times of iron loss value (at the frequency of 50Hz the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of 5t) + 100 times of thickness value. For example, dw470-50 represents cold-rolled non oriented silicon steel with iron loss value of 7W / kg and thickness of 0.5mm. Now the new model is 50W470.

As long as it is a socket connected stainless steel wire, buttress must be set through calculation.

  ·Rotary shaft, press roller, impeller, etc. in high-strength corrosion-resistant environment.

Measures to improve the welding quality of stainless steel pipe in order to ensure that the outer surface of stainless steel pipe is not damaged and purified, the maintenance of stainless steel pipe should be strengthened in each process of consumption, mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) , avoid the machining platform of austenitic stainless steel and carbon steel or solid overhead.

When brown rust spots appear on the surface of stainless steel pipes people will be surprised: & ldquo; Stainless steel pipes are not rusty. Is there a problem with the steel quality;. In fact,Stainless steel pipe installation, tractor and other industries.

mdash; Martensitic precipitation hardening stainless steel.

At this time this is a one-sided wrong view because the understanding of stainless steel pipe is not comprehensive enough. You should know that stainless steel pipe will rust under certain conditions.

Quality documents.Usage: widely used in automobile, we usually answer directly: no! What we produce is stainless steel decorative pipe, which belongs to stainless steel slotted pipe. It can not be used as stainless steel water pipe. If you want to choose stainless steel water pipe, you must choose stainless steel pipe.

Surface treatment difference: surface treatment is usually divided into polishing, wire drawing and wire drawing, and the cost is about 1 yuan and 1 meter. If it is thrown into the lens barrel, the cost per ton will increase by 3000 yuan.

how much.Before connecting the pipe fittings, mark the depth on the pipe first, so as to prevent it from being inserted in place and stuck.

For business people, it is better to spend less under feasible conditions. For goods such as stainless steel pipes, we can often see that there will be packaging film bags on them. Although they are not heavy,304 stainless steel pipe, if there are a large number of single purchases, they will also produce certain economic expenses, but why do many people clearly dislike this thing on stainless steel pipes, But I have to accept it. Next, xincoral Xiaobian will tell you why stainless steel pipes need packaging bags.

Corrosion resistance most stainless steel products require good corrosion resistance. Stainless steel pipe is similar to class I and II tableware, kitchen, water heater, water dispenser, etc. Some foreign businessmen also test the corrosion resistance of products: use NaCl aqueous solution to warm to boiling. After a period of time, the solution is to drain, wash and dry,Specification of stainless steel square pipe, and determine the weight loss to determine the degree of corrosion.

.Stainless steel capillary material: SUS301 / sus; Inner diameter 4mm-10mm, polished. Purpose of stainless steel capillary: automatic instrument signal tube, automatic instrument wire protection tube; Precision optical ruler circuit, industrial sensor, electronic equipment circuit protection tube; Safety protection of electrical circuit, capillary protection of thermal instrument and internal support of air core high-voltage optical cable. Stainless steel capillary characteristics: it has good resistance, corrosion resistance, high temperature resistance, wear resistance, tensile resistance, water resistance, and provides excellent electromagnetic shielding performance. Stainless steel hose can be bent into various angles and radius of curvature and has the same durability and durability in all directions; The stainless steel hose has flexible pitch, good flexibility and no blocking and stiffness; The stainless steel threading hose has certain tension resistance between the side buckles of each section to prevent the internal laying of the hose from outside. It is a special product manufacturing enterprise integrating R & D, stainless steel coil and stainless steel belt, Stainless steel pipe. The axial tension can withstand 6 times of the nominal inner diameter. The yield strength of duplex stainless steel is more than twice that of ordinary austenitic stainless steel. This characteristic makes the designer reduce the weight when designing products, making this alloy more cost-effective than 317L. This alloy is especially suitable for - 50 DEG; F/+600° F temperature range. For applications beyond this temperature range, this alloy can also be considered, but there are some, especially for welded structures& middot;Pressure vessel, high pressure storage tank, high pressure pipeline, heat exchanger (chemical processing industry).

The content of chromium, molybdenum and nitrogen in local corrosion-resistant duplex stainless steel makes it have strong ability to spot corrosion and interstitial corrosion in oxidizing and acidic solutions.

There are ba face, 2b face, (white skin), 2D face, (frosted), HL (wire drawing), 8K face and other surfaces with good quality and brightness.
