Drainage collector and processing method thereof

Abstract

The invention discloses a drainage collector and a processing method thereof. The drainage collector is integrally formed and sequentially comprises a first connecting pipe seat, a tank body, an end socket and a second connecting pipe seat, and the side surface of the tank body can also be provided with a side surface connecting pipe seat. The processing method of the drainage collector comprisesthe following steps of selecting a straight steel pipe as a tank body raw material; closing one end of the steel pipe to form the end socket and the second connecting pipe seat; and upsetting the other end of the steel pipe to form the first connecting pipe seat. The drainage collector is integrally formed and is good in reliability, attractive and elegant in appearance, convenient to maintain andsingle in material specification, one drainage collector can be machined only through one specification of raw materials, and the raw materials are saved. According to the processing method, a largenumber of welding processes and corresponding nondestructive testing are omitted, the process is simple, the efficiency is high, a large number of process expenses and nondestructive testing expensesare saved, and the mechanical property of a finished product is equivalent to or improved to a certain extent compared with that of a raw material through closing, upsetting and other forming processes.

Description

technical field [0001] The invention relates to a hydrophobic collector and a processing method thereof, belonging to the technical field of pressure vessels and pressure piping components. Background technique [0002] Drainage collectors, also known as hydrophobic collectors, are used to collect and discharge condensed water in steam pipes. Generally, the branch pipe is drawn from the pipeline and welded on it. Hydrophobic collectors are mainly divided into Type A and Type B. According to the standard of China Electric Power Planning and Design Association "Typical Design of Steam and Water Pipeline Parts and Components in Thermal Power Plants (GD2016)", standard number: T / CEPPEA / Z5002-2017, the hydrophobic collector is welded by the combination of pipes, sockets and heads. to make. It looks like figure 1 shown. The left side of the hydrophobic collector is a large connecting seat, which is generally welded to the side of the pipe. Since it is directly connected to th...

AI Technical Summary

Problems solved by technology

Among them, the specifications of the materials used for the hydrophobic collector are various. The large connecting seat on the left, the middle tank body, the small connecting seats on the upper and lower sides, the head, and the connecting seat on the right all require raw materials of different specifications and are machined separately. Therefore, machining More raw materials will be lost

Secondly, a large number of welding processes are required, the welding workload is relatively large, and welding defects are prone to occur

Moreover, due to the complex process, many process steps, long processing cycle and low efficiency
