1,Cast Iron Manhole Cover Description :
A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.
Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 50 kilograms (110 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorised people not having suitable tools to remove them.
A manhole cover sits on metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.
2,Main Features of the Ductile Iron Manhole Cover:
·High endurance

5，FAQ:
We have organized several common questions for our clients，may help you sincerely：
Q. Can I fit a square manhole cover into a round chamber?
A. Yes, there are a select few manhole covers which are square-to-round, meaning they will fit square or round chambers.
Q. I have a heavy traffic manhole cover but it has been broken by a forklift, why?
A. Forklifts have solid wheels which apply pressure differently to standard pneumatics and therefore covers must be specially adapted to suit this.
Q. I’ve measured my clear opening size but none of your covers match it, can you offer anything?
A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require.
Q. The project I’m working on requires a manhole cover with a quality finish, what’s available?
A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.
Q. Odours are coming through where I have installed my manhole cover, why?
A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable.
Q. I need access through my manhole cover on a regular basis, is this possible?
A. Yes, the majority of covers have built-in lifting keys, and for those that don’t we also supply lifting keys. However, the best way to obtain easy access is to have a bespoke, hinged manhole cover.

- Aqua regia or Royal water can dissolve metals. It is a mixture of conc.nitric acid and conc.hcl in the ratio of 1:3. Remember none of the above mentioned acids will dissolve the metals in the absence of other.
- Q: ok their are huge fights over what is quot;realquot; metal people say any band that is in any genre with quot;corequot; in it isn't metal or nu-metal isn't. some say power metal isn't real metal since it uses clean vocals and sometimes symphonic sounds like rhapsody of fire. well you get what I am asking. people say that these certain bands are metal and these others arn't. personally I consider a wide range of bands to be metal except for a few mostly the bands supported heavily at hot topic since their quot;fansquot; are mostly young kids who think dressing quot;scene/emoquot; is cool and since I never see any older metal heads liking any of these bands so yeah
- Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted guitars, tremolo picking, deep growling vocals, blast beat drumming, minor keys or atonality, and complex song structures with multiple tempo changes. Black metal is an extreme subgenre of heavy metal music. Common traits include fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, blast beat drumming, raw recording, and unconventional song structures.
- Q: topics in metal working
- When you can't go forward,you must go back to the roots and reinvent them.I'd rather have a new Sabbath or Priest type metal band than some nu metal,psuedo metal crap.Metal has always been about the feeling,the rush,the excitement,the power.That has nothing to do with speed or technicality.Metal is famous for being extremely tight.if a band could incorporate that tight but loose feel of a Stones or Zeppelin into pure metal,that would be a good step.
- Q: Black Metal for me. The only death metal band I really enjoy (though TBH, I'm still exploring the genre) is Death. Black metal is more ambient and atmospheric, IMO.
- The term scrap metal encompasses both ferrous and non ferrous metals: ferrous - steel, iron, HMS and Non ferrrous - copper, aluminum, brass, bronze etc. Within each scrap metal category there are different grades, for example there is #1 HMS steel, #2 HMS steel, Bare brite Copper, etc.
- Q: is it a metal that acts like a non-metal or other way around?
- Magnetism has to do with unpaired electrons. Electrons spin clockwise or counter clockwise. Generally they are paired. When they are not they create magnetism. Iron has 3 unpaired electrons and demostrates tahe greatest magnetism. cobalt and nickle also demonstrate some magnetism. Also, some of the rare earths and some alloys such as Alnico and steel. RECENTLY, several papers have been published on the use of polarized light for revealing the grain structure of metals and alloys. Hone and Pearson1 showed that by examining under polarized light a polished aluminium surface which had been anodized in a suitable electrolyte, the grain structure was revealed, differently oriented grains appearing with different brightnesses. Woodward2, by etching 'Monel' metal in a specific reagent, has found similar effects. Polished surfaces of aluminium and 'Monel' metal, being optically isotropic, do not react to polarized light as do the optically anisotropic surfaces of tin, zinc, cadmium, etc., and the above authors1,2 have attributed the optical anisotropy of the anodized aluminium and etched 'Monel' metal to the anisotropic properties of the surface film formed during anodizing or etching. Although this explanation may be correct, there is a possible alternative which involves the surface contour of the specimen, for it is well known that if pearlite is examined under polarized light no reaction occurs unless the specimen is etched. This has been shown convincingly by Baeyertz3 to be due to the presence of fine parallel grooves on the surface, formed by etching away the ferrite and leaving the cementite lamell? in relief. Furthermore, Jones4 has shown that polarization effects can be produced by deeply etching a metal surface.
