There are 3 contrasts between cast iron lines and consistent and electrifies steel pipes.
One, the outline of the three is unique.
- Outline of solid metal lines: Pipes made of solid metal cast into shape.
2, the outline of consistent steel pipe: made of the entire piece of metal, the outer layer of the steel pipe without creases, called consistent steel pipe.
3, outline of excited steel pipes: otherwise called aroused pipes, steel pipes electrifies by electroplating on the outer layer of the steel pipe.
Second, the attributes of the three are unique.
1, the attributes of solid metal line: in the low and medium strain organization (by and large utilized for under 6MPa), malleable iron line has a protected and dependable activity, low breakage rate, simple and quick development and support, incredible enemy of consumption execution, and so on
The recently evolved “Rock Shield” series of lines can be utilized for non-uncovering development and are generally utilized in the development of pipelines crossing streams, streets and structures. The “Sai Zinc” series of lines utilize an exceptional zinc-aluminum combination covering cycle to further develop the consumption opposition of the lines a few times, and are generally utilized in the development of destructive soils.
- Qualities of consistent steel pipes: no surface joints.
3、Characteristics of stirred steel pipes: uniform covering, solid attachment, long help life, and so on Stirred cost is low, the surface isn’t exceptionally smooth, and its own consumption opposition is a lot of more regrettable than that of hot-plunge excited pipes.
Three, the utilization of the three unique.
1, the utilization of solid metal line: reasonable for new, extended and changed common and modern structures indoor and open air pipe breadth DN50mm ~ DN300mm, interior strain isn’t more than 0.3MPa attachment and clip type association of dark cast iron line and its supporting fittings of life seepage pipe, water pipe, non-disintegration modern creation squander water line and precipitation pipe.
2, the utilization of consistent steel pipe: consistent steel pipe is generally utilized. Broadly useful consistent steel pipe is moved from standard carbon primary steel, low combination underlying steel or composite primary steel, the most creation, primarily utilized as a pipeline or primary parts for the vehicle of liquids.
3, the utilization of aroused steel pipe: regularly said stirred pipe is currently predominantly used to ship gas and warming. Excited pipe as a water pipe, following a couple of long stretches of utilization, the cylinder delivers a ton of rust scale, the surge of yellow water not just dirty the sterile product, and blended with unsmooth internal divider reproducing microbes; rust consumption brought about by exorbitant weighty metal substance in the water, genuinely jeopardizing human wellbeing. In the sixties and seventies, created nations started to foster new sorts of cylinders, and in a steady progression restricted aroused pipes.
The principle contrast between cast iron lines and steel pipes is that they are utilized for various purposes, china galvanized malleable iron pipe fittings have various attributes and are characterized in an unexpected way.
1、Different employments
Project iron line is reasonable for new development, extension, change of common and modern structures indoor and clasped association of life seepage pipe, water pipe, modern waste water line and downpour trickle pipe.
Steel pipe is utilized for conveying liquids and powder solids, trading heat, producing mechanical parts and holders, and is a financial steel. The utilization of steel lines to fabricate space brackets, segments and mechanical backings for building designs can decrease weight, save 20-40% of metal and accomplish industrialized automated development.
2、Different attributes
Project iron line enjoys the benefits of protected and solid activity, low harm rate, helpful development and upkeep, and magnificent enemy of consumption execution.
Steel pipe has a straightforward creation process, high creation proficiency, an assortment of details, less interest in gear; consistent steel pipe and round steel and other strong steel, contrasted with a similar twisting, torsional strength of monetary steel.
3、Different characterization
Project iron lines can be isolated into three classifications: straight lines, fittings and extras. From the point of interaction structure can be separated into W-type adaptable cast iron seepage pipe, B-type adaptable cast iron waste line and A-type adaptable cast iron waste line. As far as material: malleable iron seepage pipes, dim cast iron waste lines.
As indicated by the creation strategy, steel lines can be partitioned into consistent steel pipes and consistent steel pipes. Consistent steel pipes are alluded to as straight crease steel pipes. As per the line material (for example steel grade), it tends to be separated into carbon and composite lines, treated steel pipes, and so on As per the line end association technique, it tends to be isolated into light lines (without strung pipe closes) and strung pipes (with strung pipe closes).
The contrast between aroused steel pipe and consistent steel pipe is that
1, the definition isn’t something similar: consistent steel pipe is made of the entire metal, the outer layer of the steel pipe without creases. Aroused steel pipe is a welded steel pipe with a hot plunge or electro electrifies layer on a superficial level.
2, crippled not the equivalent: electrifies steel pipe in the virus aroused steel pipe has been prohibited in the sixties and seventies, the worldwide created nations started to foster another kind of line, and in a steady progression restricted excited pipe. China’s Ministry of Construction and other four services additionally gave a reasonable from 2000 prohibited stirred pipe as a water supply pipe, the virus water pipes in new networks have seldom utilized aroused pipes, a few networks utilize excited pipes for heated water pipes. Consistent steel pipe isn’t prohibited.
3, the utilization of various: consistent steel tubes are principally utilized for petrol geographical penetrating cylinders, petrochemical breaking tubes, kettle tubes, bearing cylinders, as well as vehicles, farm haulers, aeronautics with high-accuracy underlying steel tubes. Hot-plunge electrifies steel pipe is broadly utilized in development, hardware, coal, synthetic, electric power, railroad vehicles, auto industry, roadways, spans, holders, sports offices, rural apparatus, petrol apparatus, prospecting apparatus and other assembling enterprises.
