配管工は給水、排水などの配管を専門に施工する衛生配管工と、冷暖房などの配管を行う空調配管工に大別される。
両者とも、冷温水、蒸気、油などの流体を必要な場所へ送るために、管を切断したり、ねじ切りしたり、曲げたりして加工し、継手でつなぎ、弁などの付属品とともに所定の位置に取り付ける作業を行う。管の材料は、鋼、鋳鉄、銅、合成樹脂及びそれらの組合せなどがあり、管の接合法には、ねじ接合、溶接、接着などの方法がある。
衛生配管工は各種ポンプ、給湯機などの機械回りの配管、浴槽や便器、洗面化粧台をはじめ、各種衛生器具などの取り付け及びスプリンクラーなどのいわゆる消火設備の取付・配管作業を行う。
空調配管工はボイラー、冷凍機、空調機などの機械の据え付け、機械回り溶接配管などを行うほか、送風機や空気清浄機の据え付け、保守も行う。
配管工には、管工事業を自営している人と、企業に勤務している人とがあり、自営や企業内で管理的な立場にあるときには、資材の手配、作業員の手配なども重要な仕事になる。

Today ¥5.23M → in 3 years ¥5.79M → in 5 years ¥6.20M → in 10 years ¥7.35M (10-year range ¥6.32M–¥8.54M). The model assumes pay growth of +3.5% per year.
What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 配管工? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 配管工
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
