Spray Machine: Causes of Slippage Inside the Polyurethane Spray Machine’s Pipeline
Release Date:
Nov 26,2020
Driven by the sustainable development of the exterior wall insulation industry, we are seeing a growing number of buildings employing polyurethane spray‑on insulation technology. As a widely used polyurethane waterproofing spray‑on equipment, the demand for high‑pressure polyurethane sprayers has been steadily declining. Today, we will focus on the causes of pipe slippage in polyurethane spray‑on machines.

Today, we mainly discussed… Polyurethane spray machine The causes of pipe slippage.
Polyurethane pipelines expand when heated, which can lead to certain changes and potential displacement. Moreover, the structural layer and the outer jacket typically form a continuous, 360-degree structure. External fixation requires that the working steel pipe and the external protective casing be securely anchored together; at each pipeline section and at both ends of the expansion joints, two medium-sized reinforced concrete piers should be installed to facilitate reliable pipe anchoring, despite the inherent difficulties involved.
Based on this clear trend, it is evident that polyurethane waterproofing spray‑machine technology is becoming increasingly mature, and the use of high‑pressure polyurethane sprayers is steadily expanding alongside the deployment of various polyurethane spraying systems. We will focus on the causes of pipe slippage in polyurethane foaming machines: the insulation material of the thermal‑insulation pipe in polyurethane spraying equipment is bonded to the working steel pipe through a specific manufacturing process, forming an integrated, all‑encompassing structure. As the pipeline undergoes thermal expansion, both the insulation assembly and the steel pipe must move in unison. A gap of 10 to 20 mm exists between the outer casing and the insulation layer. This innovative structural design not only provides excellent thermal insulation but also serves as a drainage channel. The working steel pipe and the outer casing are supported at set intervals by a set of insulated guide brackets, reducing friction during pipe movement and enabling smoother, faster displacement.
