The cast iron pipe of the old house is leaking, and a lot of glue is used, but it doesn t work, who

I don't know if it is the leakage at the interface of the cast iron pipe, or the leakage of the cast iron pipe because of the sand hole.

Cast iron pipes can be welded with an electric welding machine, welded with cast iron electrodes, hire a good welder, think you can do it.

Another way is to use cement plaster, which can be used in the cement, and the general one can also be plastered.

Let's see which method is suitable for you.

Caihong plastic steel mud can solve this problem, and after curing, it is completely integrated with the water pipe, so there is no need to worry about water leakage.

Cast iron pipes can be partially replaced.

If the water pipe leaks, you can choose to directly replace the leaking water pipe with a new water pipe, or you can choose to use glue to successfully repair it.

After the surface of the water pipe that needs to be bonded is generally cleaned, it is glued immediately after gluing on one side, and the glue positioning time is 8-15 minutes at room temperature, if the glue layer is thicker, the positioning time will be relatively extended, 3-5 hours to reach a certain bonding strength, and the best bonding strength can be reached after 24 hours, at this time the strength and temperature resistance test can be carried out.

It can be cross-linked by combining with moisture in the air at room temperature, and vulcanized into high-performance elastomers, an excellent binder and sealant for metallic and non-metallic materials.

The rubber material can be well bonded with metal, glass, ceramics and many other materials, and can be used for a variety of electronic components.

It plays the role of bonding and sealing;

The water pipe leak was repaired with 137 special glue.

Summary. Hello boss! <>

If the water pipe is still leaking, you can't use caster glue directly: No, caster glue can't stick to the sand hole that is leaking. Casting glue is a new type of repair agent, which is mixed by two raw materials when used, and the two raw materials are respectively loaded with two hoses, and press 1:

Mix with a ratio of 1 and apply to missing or leaking sand holes. Since it takes a while to harden, it is impossible to block the leaking trachoma that will break through the softened glue. Cast iron, cast steel, non-ferrous and other castings have appearance defects on non-assembly surfaces and non-working surfaces, such as shrinkage holes, pores, sand holes, pits, etc., if they are used to hinder the quality, if they are scrapped, it will form a great waste.

Casting repair technology is often used. Without affecting the strength and performance of the casting, the preferred method is to use caster repair adhesive. <>

I can't change it, I want to use glue, what glue do you say?

Plugging the leak. Cast iron sewer pipe and PVC pipe connection: 1, seal with plugging spirit at the interface, (building materials stores are sold) 2, use a PVC reducer to change the diameter, and the iron pipe is inserted into the reducer; Water pipes are the pipes of water supply, modern decoration water pipes are the use of buried wall construction, there are three types of water pipes, the first type is metal pipes, such as the hot-dip cast iron pipe orange mountain section of the inner enamel plastic, copper pipe, stainless steel pipe, etc.

The second category is plastic composite metal pipes, such as plastic composite steel pipes, aluminum-plastic composite pipes, etc. The third class is plastic pipes, such as PB and PP-R.

Is there any good material?

Dear, the current query is the above.

1. It is possible to replace the PVC pipe that is commonly used now. Cast iron sewer pipe and PVC pipe connection: congestion leakage seal at the interface.

Use a PVC reducer to change the diameter, and the iron pipe is interpolated into the reducer; The water pipe is the pipeline of water supply, and the modern decoration water pipe is built with buried wall, and the plastic pipe, such as PB and PP-R.

2. Cast iron welding rods are required for repair, which is expensive and inconvenient. If it is inconvenient to change and it is troublesome to weld, you can also use glue (the kind of large jar of about 500 grams) to glue, but you need to polish it with a wire brush, and it can't withstand much pressure.

In the 80s, the sewer pipes of the old houses were made of cast iron pipes, which were easy to rust over time, and the inner wall of the pipes was easy to be blocked due to burrs over time, resulting in leakage. Either remove each section for unclogging before installing. At present, PVC-U hose is generally used for house sewer pipes, and the inner wall is smooth and drainage, which is not easy to cause blockage.

How to repair the broken and leaking iron pipe? Kiss! Hello, happy to answer your <>.

The repair method of rupture and leakage of ferrous water pipe is as follows: 1. Use cast iron welding rod for welding repair. 2. When most people do not use water, polish the cracks and leaking places, apply epoxy resin to the cracked places, and then wrap a layer with white gauze or glass ribbon, and then apply a layer of epoxy resin to repair it.

3. Make two U-shaped hoops with a width equal to the length of the crack and a radius equal to the outer radius of the cast iron sewer pipe, first wrap the cracks and leakage of the pipe with a rubber plate with a thickness of 1-2 mm, and then use the made hoop to tightly hold the rubber plate and the pipe, so that there will be no more water leakage. 4. Use a good quick-drying cement to grind a layer of cracks and leakage water, and then temporarily fix the cement plastering layer, and remove the fixing object after the cement solidifies. 5. Use marble glue (special glue for marble stone) to bond and repair.

6. Now there are many adhesives that can deal with water seepage, the key is that you must first clean the surface of the place to be treated, you can go to the supermarket to buy a kind of adhesive called "brother and sister", A and B double components, a total of 20 grams, treat the water seepage clean, make it dry, mix according to the instructions for use, and apply it to the cracks; This product is more than 3 yuan a group, do not buy stalls, because there are fakes. 7. Go to the hardware store to sell high-pressure tape to wrap around the water outlet for 3 to 5 years, and it is recommended to change the pipe. 8. The way to repair the leakage of the sewage pipe is to clamp the splint with a hoop (between the splint and the sewage pipe, smear some putty).

Repairing water pipes on the road outside is all this method. 9. The problem can be solved with the leak-proof king, and it is best to rivet it with aluminum rivets, such as small sand holes, and aluminum wire rivets can be used. 9. There is one easiest way:

Smear the sand hole with glass water (which is available at the building materials store) and sprinkle with dry cement; Smear another layer of glass water and sprinkle another layer of dry cement. 10. If the sand hole is small, it is glued with tape, there is a kind of aluminum-platinum tape, which can be torn and glued, this kind of tape can also be glued to iron basins or something, and it has to be sold everywhere, not afraid of water. 11. There is a mold repair agent on the market, which is specially aimed at the crack porosity trachoma of metal parts.

12. Buy a bottle of silicone, take some raw material tape, borrow a silicone gun, wipe the surface of the water pipe clean, put a layer of silica gel in the leaky place, and then wrap the raw material belt. Wrap more width, and then play some silica gel to wrap a layer, and then wipe the silica gel again after wrapping the layer, it is OK after drying, and you can't leak anything in the future, pay attention to the raw material belt to be wound tightly. 13. Use AB type quick-drying mud, 53 yuan, like the size of soap.

14. There is a kind of cast iron pipe leakage remedy multiple seals, which is composed of a pair of fastened sealing shells, in the left and right port slots of the sealing shells, the left and right sealing rings with sawtooth and lip cross-sections are respectively placed, the sealing ring has only one oblique joint that is staggered with the joint surface of this pair of sealing shells, and the sealing strip with concave and convex cross-section is placed between the connecting surfaces of this pair of sealing shells, and the bolt group seals this pair through the screw holes on the connecting surface.

YH-101 metal repair agent can be applied to the sand hole gap of the pipeline, and the leakage can be plugged for 10 years.

Metal repair agent (iron + steel + alloy + other metals) can be well repaired for various casting sand holes, cracks, corrosion, defects, scratches, waterproof, oil-resistant and corrosion-resistant.

Commonly used in: metal pipes, heating pipes, water tanks, fuel tanks, engines, mechanical equipment.

Composition: metal powder + imported heat-resistant polymer synthetic resin will not degum for ten years.

High temperature resistance 200 degrees, minus 50 degrees.

The curing time is within 2 hours, and the instruction manual + various tools are sent.

It doesn't matter if you can't use it up, seal it again, and the shelf life can be up to 2 years.

Generally, cast iron sewer pipes are gravity sewer pipes, which are no pressure or very small pressure, as long as the method is appropriate, it is easy to repair, and cast iron sewer pipes can generally be repaired by the following methods:

1. Welding: Cast iron electrode is used for welding repair.

2. Epoxy resin:

When the water consumption is small, polish the cracks and leakage water, apply epoxy resin to the cracked places, then wrap a layer with white gauze tape or glass ribbon, and then apply a layer of epoxy resin to repair.

3. Hoops: Make two U-shaped hoops with a width equal to the length of the crack and a radius equal to the outer radius of the cast iron sewer pipe, first wrap the cracks and leakage of the pipe with a rubber plate with a thickness of 1-2 mm, and then use the made hoop to hold the rubber plate and the pipe tightly.

4. Cement: Use a good quick-drying cement to grind a layer of cracks and leakage, and then temporarily fix the cement layer, and remove the fixing object after the cement solidifies.

5. Marble glue:

Bonded and repaired with marble glue (special glue for marble stones).

6. If the rust and decay of the mold repair agent are too serious, you can only consider replacing the new sewer pipe.

Mold repair agents can specifically target cracks, pores, and trachoma of metal parts to plug leaks.

7. PVC outsourcing:

Buy a larger model of foamed PUC pipe (softer, recommended) or PVC (harder) than the original cast iron pipe, after sawing along the axial direction, do not saw it in half, PVC (harder) can be sawed in half, put PUC or PVC outside the cast iron pipe, buy a pipe clamp of the same specification, tighten the hoop, narrow the gap between the sawed gap, and finally pour the mixed cement in the space between the PUC or PVC pipe and the cast iron pipe.

8. Replace the sewer pipe with a new one

If the cast iron sewer pipe has been severely corroded and cannot be used anymore, it is necessary to contact a professional maintenance personnel to replace the pipe.
