Steam boilers, powerful giants of industry and facilities, are the beating heart of many factories, hospitals, hotels and large complexes. When this beating heart has a problem, the whole system stops working and heavy financial losses are incurred. In such situations, access to a specialized authority for repairs is critical.

The vital importance of specialized boiler repairs

Steam boiler or steam boiler is a tank under pressure that turns water into steam. Due to the extremely high pressure it withstands, this device is like a potential ticking time bomb if not properly maintained and repaired. In the complete boiler repair guide in Rajabi Tehran Mobile Repairs, we have a special emphasis on safety. Improper repairs by inexperienced people not only cause the device to fail again, but also bring irreparable life risks such as explosion.

Rajabi Mobile Repairs Group, understanding this sensitivity, has assembled a team of engineers and technicians with valid welding and pressure vessel inspection certificates. We believe that boiler repair is not just a technical task, but a serious safety responsibility. In the continuation of this complete boiler repair guide at Rajabi Mobile Repairs in Tehran, we will examine common problems and our team's specialized solutions.

Common boiler problems and troubleshooting methods

To know when you need our services, you need to be familiar with common problems. In this section of the complete guide for boiler repair in Rajabi Tehran Mobile Repairs, we check the signs of failure.

1. Clogging and reduced efficiency

The water entering the boiler contains salts. If the hardener does not work properly, these salts will deposit on the pipes and furnace. The deposit acts like a thermal insulator and causes the temperature of the metal to rise and finally the pipes are deformed or punctured. Rajabi's mobile repair team performs descaling operations without damaging the body of the boiler using special acids and desclarer.

2. Corrosion and decay of pipes

The presence of dissolved oxygen in water causes corrosion of fire tubes. In the periodical visits made by the experts of Rajabi mobile repairs, the thickness of the pipes is measured with an ultrasonic thickness gauge. If the corrosion exceeds the permissible limit, it is necessary to replace the pipes (retube).

3. Leakage from network and sheet tube

One of the most dangerous cases that we deal with in the complete guide to boiler repair in Rajabi Tehran Mobile Repairs is leakage from the connection point of the pipe to the network. This problem usually occurs due to thermal shocks or poor quality previous welding. Repairing this item requires high welding and welding skills, which is our specialty.

4. Failure of burner and ignition system

Sometimes the boiler is healthy but the burner is not set. Incomplete combustion causes soot production and reduced heat transfer. At the same time as repairing the body, our technicians also perform a full burner and electrical panel service so that you get a complete package of services.

Boiler repair steps in Rajabi Mobile Repairs

Maybe you have a question, how is the work process? In this section of the complete guide for boiler repair in Rajabi Tehran Mobile Repairs, we describe the repair operation step by step.

First step: visit and thickness measurement test

After your call, our expert will be sent to the place. The first thing is to open the boiler doors and visually inspect. Then, using advanced devices, the thickness of the body, furnace and grids are measured to determine whether the boiler is worth repairing or not. Transparency in announcing the status is the first principle in Rajabi mobile repairs.

Second step: cutting and removing the defective parts

If the pipes or part of the furnace needs to be replaced, the defective parts are removed using precise cutting tools. This step is very sensitive so as not to damage the healthy parts of the boiler. In the complete boiler repair guide in Rajabi mobile repairs in Tehran, we emphasize that accuracy in cutting is the foundation of a successful repair.

Third step: preparation and cleaning of surfaces

Welding places must be completely clean and free of any oxide and grease. The networks are stoned and prepared for placing new pipes.

Fourth step: specialized assembly and welding

This is the most important step. The welders of Rajabi Mobile Repairs perform welding operations using penetrating electrodes and according to ASME standards. The quality of welding should be such that it can withstand high pressures and frequent contractions and expansions.

The fifth step: waltzing (Expand)

In firetube boilers, in addition to welding, the pipes must be rolled to completely stick to the grid and be sealed. We use automatic waltz machines with adjustable torque.

Sixth step: hydrostatic test

No pot is delivered without testing. According to the standard that we adhere to in the complete boiler repair guide in Rajabi Tehran mobile repairs, the boiler should be tested with cold water at a pressure equal to 1.5 times the working pressure. If no leakage or pressure drop is observed, the boiler is ready for use.

Retubing

One of the main services that we have to talk about in detail in the complete boiler repair guide in Rajabi Tehran Mobile Repairs is tube replacement. Boiler pipes are usually made of ST35.8, which have high thermal resistance. In Rajabi Mobile Repairs, we only use pipes with certificates and standards.

The pipe replacement process includes removing the worn pipes, cleaning the network holes (tube sheet), inserting new pipes, rolling and welding. Many unlicensed repairmen use ordinary welded pipes, which is very dangerous. But we guarantee that the consumables are of the highest quality.

Furnace and grid repairs (Tube Sheet)

Sometimes the damage goes beyond the pipes and the main furnace of the boiler is deformed (belly) or cracked. This usually happens due to dehydration of the boiler. Furnace repair is one of the most difficult types of repairs that require hydraulic jacks to reshape or completely replace the furnace. In the complete boiler repair guide at Rajabi Mobile Repairs in Tehran, we announce that our team has the ability to completely replace the furnace and the back and front networks of the boiler at your engine house.

The importance of periodic acid washing and descaling

Prevention is better than cure. In the complete guide to boiler repair in Rajabi Tehran Mobile Repairs, we recommend that you don't wait for the boiler to get punctured. Annual acid washing service can double the life of your boiler. Deposits not only increase fuel consumption, but also cause hot spots on the metal. Rajabi's mobile repair team circulates the desclar solution in the boiler with anti-acid circulation pumps to dissolve all deposits. Then neutralize the acid with neutralizing materials so that corrosion does not occur.
