A blue metal pegboard featuring a regular grid of square holes serves as the mounting surface for a technical gas flow system. A strip of yellowish‑beige wall is visible at the very top, marked by a small patch of red paint in the upper left corner and a vertical seam. A horizontal row of small red square inserts is embedded in the blue panel just below the wall section. The equipment is arranged in three main horizontal tiers. The top tier consists of a horizontal assembly of brass fittings, clear plastic tubing, and a black circular cap on the left. A small rectangular black digital meter in the center displays red LED numbers "0.10". To the right, a circular gauge with a beige housing and a bright green LCD screen displays the number "0.16" along with smaller digits and the brand text "XSENR" above small buttons. A white handwritten note with a light blue border is clipped below the gauge, bearing the Chinese text "用完归还" on the top line and "切记！" on the bottom line. To the left of the central meter on the top row, a torn piece of yellowish tape adheres to the board with handwritten characters resembling "归" and "记". The middle tier features a similar arrangement with a black cap on the left, a central black meter displaying red LED digits "0.21", and a circular gauge on the right with a green screen showing "0.18" and "XSENR" branding. A white zip tie secures a small white wire near the left section of this row. The third tier includes a brass cap angled downward on the left, a rectangular silver‑colored meter displaying red LED numbers "0.31", and a third circular gauge on the right with a green screen. Below these rows, a cylindrical brass component with vertical ports and small blue fittings is mounted centrally. Clear flexible tubing curves across the lower section, and a black cable loops downward from the central brass component. In the bottom left area, a small white label with a red border contains the handwritten Chinese text "归还" on the top line and "切记！" on the bottom line. Additional clear tubing and brass fittings extend across the bottom edge of the frame. Artificial overhead lighting creates highlights on the plastic tubing and casts shadows of the components onto the blue board.
In a close‑up industrial setting, a series of circular pressure gauges are mounted on vertical pipes. The pipes are wrapped in black insulation material with a segmented, ribbed texture and some uneven, torn sections near the base of the gauges. The gauges feature silver metallic bezels and white faces with black needle indicators and measurement scales. The gauge in the center is in sharp focus, displaying numbers such as "0", "0.4", "1.2", and "1.6", along with a central logo and Chinese text reading "耐震压力表". Below the center, smaller text includes a standard code and the word "No". A second gauge to the left is slightly out of focus but shows similar markings and numbers like "0.4" and "1.2". A third gauge is partially visible behind the central one, fading into the background. The needle of the leftmost gauge points to approximately 0.25, and the second gauge points to about 0.20. A cluster of black cables hangs loosely and curves downwards from the upper right area, draping over the equipment. To the right, a beige metal panel occupies the side of the frame, showing signs of wear with small dark scuffs and marks on the far right edge. A silver hex bolt head is visible on the panel’s surface. A vertical rectangular sticker is adhered to the panel, featuring a white upper section with a red prohibition symbol—a circle with a diagonal slash over a black graphic—and a solid red rectangular block at the bottom containing vertical white Chinese characters reading "禁止撬动阀门". Above the panel and cables, a section of a pipe is wrapped in a crinkled, silver‑grey insulation material. At the bottom right, beneath the cables and panel, a mass of white, fluffy, fibrous insulation material is piled. To the left, a grey concrete wall with a vertical seam and a faded, illegible rectangular label forms the background. In the upper left corner, a small red plastic component is partially visible. A gap between the concrete wall and the equipment reveals a background area with a light green wall and a glimpse of a ceiling structure. The image utilizes a shallow depth of field, keeping the central gauge and the warning sign relatively sharp while blurring the leftmost gauge and the distant background. The lighting is artificial and diffuse, creating soft highlights on the metallic gauge rims and the silver insulation.
