Product Description:

SSIC   Silicon   carbide   tube

SSIC   Silicon   carbide   tube

Tailor-made for customers all kinds of pumps with my company, kettle, bearing no pressure sintering silicon carbide mechanical seal, and all kinds of resistance corrosion pump parts and the accessories. Our company pressureless sintered silicon carbide products a reaction bonded silicon carbide products, can easily adapt to the harsh working conditions, in strong corrosive, strong wear, high temperature, high pressure, high strength harsh harsh under complex conditions is more outstanding. At the same time, our company to provide customers with nozzles, armored body armor plate and other special-shaped pieces of custom-made service.

Compared with the reaction sintered silicon carbide product (SSIC), the production process of the sintered silicon carbide product (RBSIC) is complex and the production investment is high. In addition, whether it is in the resistance to corrosion and abrasion, compressive and flexural fracture resistance of or high pressure, high temperature and other properties are more excellent, this is pressureless sintering silicon carbide products will in the near future completely replace reaction bonded silicon carbide products is one of the important reasons. The main varieties of the pressureless sintering silicon carbide products with all kinds of mechanical seal with sealing ring and moving ring and static ring, corrosion resistant pump, magnetic pump, shield pump components. At the same time, the production special-shaped pieces of nozzle, wire drawing die, armor plate. According to the drawings, we will provide customers with satisfactory products and customer satisfaction. Let customer satisfaction is one of the purposes of our company has been pursued, but also one of the objectives pursued by all the staff of our company.

Features: high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, hardness, heat conduction

Main products: mechanical seals, pump parts, nozzles, bullet proof plate

Mechanical seals: high hardness, high wear resistance, good self - Lubrication and high heat conductivity, so the service life of mechanical seal is greatly improved.

Pump: resistance to corrosion and wear characteristic of the pressureless sintering silicon carbide become magnetic pump sliding bearing, resistant corrosion pump sleeve, shielding pump assembly, etc. various kinds of pump of choice

Nozzle: wear resistant, high temperature resistance, high hardness characteristics of the normal pressure sintering silicon carbide nozzle to become a perfect alternative to carbide nozzle

Armor: light weight, high hardness, good ballistic performance, pressureless sintering of SiC for your life and property security escort

Assessment Method: the specimen prior polishing, immersed in the test liquid (70OC) for 100 hours, the weight was measured and observed microstructure, weight reduction is calculated by the degree of corrosion was observed microstructure for corrosion to comprehensive judgments.

A level (corrosion): corrosion rate ≤0.125mm / ingredients in a small amount of corrosion observed slice

Level B (somewhat resistant): corrosion rate = 0.125-1.0mm / or annual corrosion rate ≤0.125mm / observe a large number of corrosion

Class C (resistant to corrosion): corrosion rate ≥1.0mm / or the main ingredient of Corrosion

Q:What kind of equipment do you need to open a small seal factory?
Raw materials, if you want their own rubber, it is very troublesome, at least you have to glue formula, and then you are small-scale, raw materials are sold by the ton, you buy less, the cost will be high.
Q:National standard for mechanical seals
activeGB/T 10708.2-2000 reciprocating rubber sealing ring structure size series second parts: two-way sealing rubber ring, the State Quality Supervision, inspection and quarantine. 2001-03-01 currentGB/T 10708.3-2000 reciprocating rubber sealing ring structure size series third parts: rubber dust sealing ring, national quality supervision, inspection and quarantine. 2001-03-01
Q:Would you like to ask what glue can be used for vacuum seals?
Hello, metal repair, repair or need to fill the effect, you use our YH-T828 special glue to repair it, after curing is soft, tough, and can withstand high temperature. One convenient operation! Million adhesive Taobao (new on the market) to sell.
Q:What are the main seals used in nuclear power plants?
Nuclear power plants mainly use sealed gaskets, graphite gaskets are used in pipelines, rubber gaskets are used in non-standard equipment. Nuclear grade graphite gaskets require high levels of halogens and sulfur
Q:What are the equipment needed to produce the sealing ring?
These two are completely different materials, the rubber ring is generally rubber, PTFE is plastic, the production process is not the same. Not familiar with, or first learn more professional knowledge!
Q:Sealing type and specification of solenoid valve core
Cage or sleeve is considered large differential pressure or high pressure or large caliber valve, is now more and more common, and can add a variety of
Q:Men's motorcycle front left shock absorber oil leakage, do not change two seals?
Change this on the line, the outside is generally dust seal, to prevent soil, not oil seals, this if there is no obvious damage, you do not need to change.
Q:How to choose the sealing ring material, sealing ring of different materials, what is the difference?
Insulation performance,butSILSilicone rubber sealing ring tensile strength than general rubber poor, and no oil resistanceSIL;The silicon rubber sealing ring is suitable for household electricityAppliances such as electric water heaters, electric irons, microwave ovens, etc.,
Q:What are the rubber seals made of?
Rubber, with plastic, fiber and called the three major synthetic materials, is the only high flexibility and excellent elasticity of high polymer materials. The first characteristic of rubber is that the modulus of elasticity is very small, and the elongation is very high. Second, it has excellent breathability and resistance to a wide variety of chemical and electrical insulation. Some special synthetic rubber has good oil resistance and temperature resistance, resistance to fatty oil, lubricating oil, hydraulic oil, fuel oil and solvent oil swelling; cold can be low to - 60 DEG C to 80 DEG C, heat up to 180 DEG C to 350 C + +. Rubber is also resistant to a variety of bending and bending deformation, because the hysteresis loss is small. The third characteristic of rubber is that it can be used in combination with many materials, blending and compounding so as to obtain good comprehensive properties.
Q:What are the common materials of rubber seals for valves?
Construction machinery industry, shipbuilding industry, automobile manufacturing, hydraulic industry and so on, almost as long as there is a place where the machine will use the oil seal oh.
