Q:How can the cast iron pipe be connected?
Drain pipe or water supply pipe?. The drainage tube as stated on the first floor, water supply pipe of T type and K type and S type, currently dominated by T, a lot of Xinxing Pipes as well, when connecting with T type rubber ring socket socket into the brand, after inserted with oil. The installation team is generally safe.
Q:The role of chromium in nodular cast iron
Chromium has better strengthening and toughening effect in nodular cast iron. Chromium containing cast iron has the characteristics of high strength, high elongation, high impact value and low hardness.
Q:How can the ductile iron pipe elbow be fixed?
Ductile cast iron pipe in the groove pipe connection technology is also called the lathedog connection technology, has become the most liquid and gas pipeline connection technology, although this technology is later than foreign in domestic development time, but because of its advanced technology, domestic market quickly received. Since 1998, it has been developed and applied in just a few years. It has gradually replaced two traditional ways of pipe connection, such as flange and welding. Not only technically more mature, the market is generally recognized, but also by the national laws and regulations actively guide the policy. The application of grooved pipe connection technology makes the complex pipe connection procedure simple, fast and convenient. Took a big step forward in pipeline connection technology.
Q:How much is a ductile iron pipe dn400?
High quality cast iron ductile iron pipe with low phosphorus and low sulfur iron making production of blast furnace, according to the current international advanced centrifugal casting, annealing process, water-cooled metal type centrifugal pipe casting machine casting, after annealing, socket dressing, pressure test, internal lining layer of cement, cement treated lining, water and health cement lining, outer wall coated with asphalt paint, asphalt paint baking, socket antirust processing, spray marks and other procedures for the packaging, with high strength, high elongation, corrosion resistance of a body strong as iron.
Q:How to control mortar proportioning in ductile iron pipe cement coating
The mix ratio of cement coated mortar for ductile iron pipes refers to the weight ratio of various raw materials consisting of ductile iron pipes and cement coated mortars.
Q:How can stainless steel pipes and ductile iron pipes be joined?
Or with a gland type expansion joint, by tightening the pressure plate bolts, sealing pipe fittings and pipe wall, so as to achieve sealing, while retractable function
Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting the ductile iron pipe by grinding is grinding and cutting the ductile iron tube continuously by grinding wheel until it breaks. To cut ductile iron pipes by grinding cutting method, the cutting parts should be crossed at first so as to avoid deviation during cutting. Place the drawn ductile iron tube in the cutting machine and fix the ductile iron tube and clamp it with a built-in clamp. Next, start the cutting machine and gradually press the handle of the cutting machine. The grinding wheel cuts into the ductile iron tube until the ductile iron pipe is cut off. When exerting pressure on the handle, do not force too hard at once, otherwise it will cause the grinding wheel to break. In the operation of the machine, the operator must not stand on the side of the grinding wheel, so as to avoid accidents. When the wheel appears in cutting, vibration, shaking, uneven phenomenon, should immediately stop the operation, check whether there is the wheel gap, if damaged, must be promptly replaced, to ensure safety and normal. Good cutting ductile cast iron pipe section, if there is to prevent the use of burrs, can be removed by grinding or machining file.
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
General use of tensile machines, such as quality management, this aspect should be strictly controlled, otherwise the data is not accurate, do nothing, no one wants
Q:Ductile iron pipe connection mode
The connection mode of ductile iron pipe installation program: clean up the socket socket to clean up on the apron, apron, pipe (tube), Jack in appearance and rubber brush lubricant to push the pipe into socket to check.
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
Grade high good, mechanical performance can reach or exceed the standard, the grade is not high, the performance can not be achieved
