What is Buttweld welding cap?

Buttweld cap or welding cap is one of the most practical and common connections in industries and piping. This connection leads to blocking of the end of the pipe. با توجه به گسترده بودن کاربردهای این قطعه، از کپ باتولد در صنایع مختلفی از جمله کشاورزی، پتروشیمی، صنعتی و . . . مورد استفاده قرار می­‌گیرد. کلاهک جوشی از جنس­‌های مختلفی از جمله پلی اتیلن، فولاد و گالوانیزه تولید می‌شود. همچنین کپ‌­ها دارای رده­‌های مختلفی هستند.

How is welding cap produced?

Generally, butold or welded caps are produced by 2 thermal and tensile methods. In the thermal method, the caps are placed in the furnace under high temperature. Then, due to the fact that the tension remains on its residues, a stress relief operation should be performed. In the stretching method, metal sheets are poured into standard molds and subjected to high pressure and heat.

Types of welding caps

As mentioned, different materials are used to produce this model of buttold joints. The most important of these are as follows:

steel
Steel
Seamless or seamless
seamed
Steel welding cap

One of the best-selling and strongest buttold caps is a steel connection that is widely used in various industries. This connection is made of metal. The main material in the design of the steel cap is carbon steel. Also, in addition to carbon, raw materials and other elements such as manganese, nickel, oxygen, nitrogen are used in the design and manufacture of steel caps. In the caps with steel birth, the end of the pipe is welded to connect. Steel welding caps are made in two types, flat and lens. The steel cap is one of the most common buttold caps due to its high resistance.

What is a steel welding cap and what are its features?

Steel or stainless steel caps are also used as welded caps at the ends of pipes. The steel used in this type of caps is stainless and relatively resistant. In fact, cap is a welded joint cap that is used as a permanent cap at the end of the pipe. Buttweld caps or buttweld caps are connected at the end of the pipe through a threaded, butt-welded connection. These types of caps are divided into 2 categories, short steel and long steel. The size range of these cups is from 1 to 12.

What are the differences between Manisman or seamless cap and seamed cap?

As we mentioned above, in addition to steel and steel, there are other types of welded joint caps, such as manisman and seam caps. The difference between these caps is that the seamed cap has a welded seam, but the Manisman cap does not have any welded seams. Also, these caps differ in other aspects, including size and dimensions, application, tolerance threshold, appearance and price. Therefore, according to the producers of the Buttweld cap, the Manisman cap has a higher pressure tolerance threshold, and as a result, it has a higher price than the seamed cap.

What is the application of the welding cap and its types of connections?

Batold Cap or Joshi Cap has three classifications of 20, 40 and 80. In terms of pressure tolerance threshold, category 20 has the lowest tolerance threshold and category 80 has the highest pressure tolerance threshold. Grade 20 welding cap is used for plumbing in houses. Class 40 welding cap is used to block and close gas pipes, and class 80 buttold cap has a wider application in industries such as oil, gas, and petrochemicals.

Conclusion

Buttold cap is one of the most basic and widely used high pressure connections. These fittings have different prices according to the type of metal, production method and quality of construction. Alborz Part Jahan is one of the strongest producers of various welding caps that can provide the best quality caps to its customers.
