Subsequent Events [Abstract]
Subsequent Events	17. Subsequent Events On March 7, 2022, the Company completed the acquisition of General Rubber, LLC ("GRC") through its Effox-Flextor-Mador ("EFM") joint venture. GRC is a worldwide leader in the engineering and manufacturing of non-metallic (rubber) expansion joints and flow control products with a highly diversified industrial customer base. This acquisition advances the Company further into the water, storm water and wastewater markets, which we plan to help deliver turnkey, environmentally friendly solutions that protect critical infrastructure, piping, and flow controls for these markets. The purchase price is approximately $24.0 million and financed using debt, cash and equity from EFM. The impact of this acquisition is not included in our results for the year ended December 31, 2021. The initial accounting for the acquisition was not complete at the time the financial statements were issued due to the timing of the acquisition and the filing of this Annual Report on Form 10-K. As a result, complete disclosures required under ASC 805, Business Combinations cannot be made at this time.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
