Rigid pipe & wall sleeve with puddle flange

Fabrication solutions for pipe spools and wall sleeves with waterstop collars according to engineering drawings

In the construction of industrial and civil piping systems, penetration details through walls and concrete slabs always require precise manufacturing techniques to ensure watertightness and firm fixation. The Tan Dat Flex mechanical workshop specializes in providing fabrication services for pipe spools and wall sleeves integrated with waterstop collars, meeting the specific technical parameters of each project in Ho Chi Minh City and neighboring provinces.

Technical specifications and standard manufacturing materials

Pipe spools and wall sleeves are manufactured directly at the workshop according to the actual requirements of design engineers. Below are the basic fabrication parameters:

• Type: Pipe spools, wall sleeves with waterstop collars.
• Diameter: Available from size DN15 to DN500.
• Length: Cut and fabricated according to the exact dimensions of the project drawing.
• Primary material: Stainless steel 304, steel, galvanized steel (stainless steel 316 optional based on specific environmental requirements).
• Connection type: Welded stainless steel flanges, threaded ends on both sides, or integrated anchoring waterstop collars.
• Welding standard: Deep penetration welding, with thorough cleaning of welding slag.

Practical applications of wall sleeves with waterstop collars

Specially designed for piping locations passing through walls or partitions of swimming pools and underground water tanks, the product acts to anchor and fix the pipes firmly while preventing water leakage infiltrating through concrete gaps. Frequently applied categories include:

• Building water supply and drainage systems, industrial zones.
• Wall-penetrating and slab-penetrating fire protection (PCCC) piping.
• Water supply pump stations, irrigation systems, and wastewater treatment plants.
• Domestic water storage tanks and chemical storage tanks in factories.

Quality inspection and ex-works process at Tan Dat Flex

To ensure durability and load-bearing capacity for the piping system, every product must undergo strict inspection steps before leaving the production workshop:

• Visual inspection: Evaluate material surfaces, flange flatness, and actual dimensions against drawings.
• Weld inspection: Carefully observe the collar welds and flange joints to ensure no cracks or porosity.
• Pressure testing: Conduct pressure tests on 100% of finished products to eliminate technical defects prior to delivery to the project site.
