1, said unique.
Hot-plunge electrifies steel pipe for the most part alludes to the standard ostensible distance across of water pipes composed images with DN. Hot-plunge aroused steel pipe SC demonstrates that the wire is laid through the steel pipe (low-pressure liquid welded steel pipe) SC is standard welded steel pipe, equivalent to the DN of the water proficient SC is welded steel pipe disguised, the overall divider is thicker, S addresses the line, C addresses the laying strategy.
2, the interaction is unique.
Hot-plunge aroused covering is thick, so the erosion obstruction is solid. What’s more hot-plunge stirred steel pipe SC uniform, the surface quality is better, the thickness of the covering is by and large between a couple of microns to twelve microns. Hot-plunge exciting is a compound treatment, which is an electrochemical response. Hot-plunge electrifies steel pipe SC is an actual treatment, simply a layer of zinc brushed on a superficial level, there is no galvanisation inside by any means, so hot-plunge stirred steel pipe SC is not difficult to tumble off. Hot-dunk exciting is for the most part utilized in building development.
What hot-plunge aroused steel pipes and hot-plunge stirred steel pipes SC share practically speaking is that both are electrifies steel pipes.
Hot-plunge electrifies steel pipe specialized necessities
1, grade and synthetic creation
The grade and synthetic creation of steel for electrifies steel line should be as malleable iron galvanized pipe fittings per the grade and compound structure of steel for dark line as determined in GB/T3092.
2, fabricating strategies
The assembling strategy for dark line (heater welding or electric welding) is picked by the producer. Arousing is finished by hot plunge stirring strategy.
3、Threads and pipe joints
(a) For stirred steel pipes conveyed with strings, the strings should be turned after galvanisation. The strings ought to follow the arrangements of YB 822.
(b) Steel pipe joints will consent to the arrangements of YB 238; flexible cast iron line joints will follow the arrangements of YB 230.
4、Mechanical properties The mechanical properties of steel pipes prior to arousing will adjust to the arrangements of GB 3092.
5, the consistency of the aroused layer of stirred steel line ought to be made to test the consistency of the excited layer. Steel pipe examples in copper sulfate answer for 5 continuous plunges will not become red (copper plating tone).
6, cold bowing test ostensible distance across of not more than 50mm excited steel line should be cold twisting test. Bowing point of 90 °, the twisting span of multiple times the external distance across. Test without filler, the example weld should be put toward twisting or the upper side. After the test, the example ought not have breaks and zinc layer chipping with the picture.
7, water powered test pressure driven test ought to be done in the dark cylinder, can likewise be utilized rather than swirl flow defect location water driven test. Test tension or whirlpool current defect location contrast example size ought to be predictable with the arrangements of GB 3092. Steel mechanical properties is to guarantee that the steel end-use properties (mechanical properties) of significant pointers.
As per the public standard chart book “normal realistic and text images for building electrical designing plan” (00DX001) in the arrangements: SC – said the wire through the welded steel pipe laying. SC (run in welded steel duitconSC is the public standard arrangements of the line laying way letter code one, said the wire is through the steel pipe hiding out (pressure liquid Welded steel pipe), SC is a normal welded steel pipe, equivalent to the water proficient DN SC is welded steel pipe disguised laying, the overall divider is thicker, S addresses the line, C addresses the laying strategy. For instance, SC70 implies that the guide utilizes DN70 low-pressure liquid welded steel pipe as a security pipe for laying, DN70 implies that the ostensible measurement of this steel pipe is 70mm, and that implies that the ostensible inward breadth of the steel pipe is 70mm.
Hot-plunge electrifies steel pipe by and large alludes to the standard ostensible width of water pipes composed images with DN.
Hot-plunge aroused steel pipe and hot-plunge excited steel pipe SC share for all intents and purpose that both have a place with electrifies steel pipe.
