Standard wall thickness tees are used for branching, diverting, and merging of the main pipe in piping systems, and are basic pipe fittings with large usage in standardized piping networks. This product we manufacture is produced according to general standards such as GB/T12459, GB/T13401, ASME B16.9, DIN, JIS, etc. The wall thickness is implemented according to standard grades such as SCH10, SCH20, SCH40, SCH80, STD, XS, etc., with diameters from DN15 to DN1200. Structurally, there are equal-diameter, reducing, and 45° lateral tees; connection methods include butt welding, flanging, socket welding, and threading; materials are mainly carbon steel, stainless steel, and alloy steel. During procurement, attention is usually paid to whether the wall thickness meets standards, whether the port dimensions are consistent with existing pipelines, and whether batch supply is stable. If you have specific diameter, wall thickness grade, and material requirements, welcome to contact us to confirm the configuration and quotation.
Overview
Standard wall thickness tees are basic pipe fittings used in pipeline systems for diversion, confluence, and branch direction change. We produce according to general standards such as GB/T12459, GB/T13401, ASME B16.9, DIN, JIS, etc. Wall thickness follows standard grades such as SCH10, SCH20, SCH40, SCH80, STD, XS, etc., with diameters covering DN15–DN1200. Products have three structures: equal diameter, reducing, and 45° lateral tee. Connection methods include butt welding, flange, socket welding, and threaded. Materials are mainly carbon steel, stainless steel, and alloy steel. It is suitable for standardized pipeline engineering in municipal, heating, petrochemical, power, industrial equipment, etc. Buyers are usually engineering contractors, construction teams, equipment installation companies, and foreign trade pipe fitting wholesalers.
Key Features
The main features of this tee are that wall thickness follows standard grades, pipe wall thickness is uniform, reducing the problem of weak pressure-bearing areas caused by eccentric walls and local thinning. Dimensions are produced according to general standards, with good interchangeability when connecting to pipes, valves, and flanges of the same specification, and generally no secondary re-beveling or diameter modification is needed on site. Diameter and wall thickness grade coverage is relatively wide, with equal diameter, reducing, and 45° lateral tee options, capable of adapting to most conventional pipeline layouts. Materials include carbon steel, stainless steel, and alloy steel, corresponding to working conditions such as clean water, sewage, steam, gas, ordinary oil and gas, and neutral chemical media. Conventional small-diameter in-stock styles have low minimum order quantities, suitable for engineering replenishment and sporadic replacement.
Applications
Standard wall thickness tees are mainly used for branching and confluence in standardized fluid pipeline networks. In the municipal field, they can be used for new construction and replacement of conventional water supply and drainage, fire protection, and gas pipeline networks; in the heating and water conservancy field, they can be used for factory heating pipeline networks, small and medium-sized steam pipelines, and water transmission pipelines; in the petrochemical field, they can be used for conventional oil and gas, neutral chemical fluids, and mildly corrosive process pipelines; in the industrial equipment field, they can be used for pipeline connection of electromechanical equipment, fluid conveying equipment, and general-purpose units; in the building field, they can be used for building water supply and drainage, HVAC, and fire protection diversion systems. On the foreign trade side, they are suitable for bulk procurement by general pipe fitting wholesalers and centralized procurement replenishment for engineering projects.

If you need a specific diameter, wall thickness, material, or interface form, welcome to contact us to confirm the configuration.
Purchasing & Delivery
For DN15–DN100 conventional small-diameter standard wall thickness in-stock styles, MOQ is as low as 10 pieces, suitable for engineering replenishment and sporadic replacement. We routinely keep conventional standard wall thickness tees in stock. For the full DN15–DN100 series, after order confirmation, counting, re-inspection, packaging, and shipment can be completed within 24 hours. For other diameters and customized specifications, please contact us to confirm minimum order quantity and delivery time. Packaging adopts anti-collision, anti-deformation, and moisture-proof solutions. Welding bevels, flange sealing surfaces, and threaded ports are equipped with dust plugs and anti-collision protective rings. The outer walls of carbon steel pipe fittings are treated with rust prevention, and stainless steel pipe fittings are individually isolated and packaged. Full-container foreign trade shipments use fumigation-free solid wood pallets and steel strapping for reinforcement, and English shipping marks, specifications and models, batch identification, and customer LOGO can be customized.
Service & Support
Before sales, according to your engineering standards, pipeline system, and working condition media, we can assist in matching the corresponding national standard and American standard wall thickness models, reducing selection mismatch and specification mismatch. Before leaving the factory, products undergo wall thickness verification, dimension calibration, appearance fine inspection, hydrostatic pressure testing, and sealing spot checks. Warranty is 18 months, with 7×24 hour response. After sales, we provide pipeline installation adaptation guidance, conventional pipeline network operation and maintenance Q&A, and assistance with bulk goods counting, with full-process logistics tracking to assist overseas customers with rapid customs clearance. If you have specific project requirements, welcome to contact us to confirm configuration and quotation.
FAQ
What is the difference between standard wall thickness tees and ordinary non-standard tees?
Standard wall thickness tees are produced according to general standards such as GB/T12459, ASME B16.9, etc. The wall thickness follows standard grades such as SCH, STD, XS, etc. Tolerance control is relatively strict, and dimensions are interchangeable with standard pipes of the same specification. Non-standard tees often have uneven wall thickness, may have eccentric walls or local thinning, and may require secondary re-beveling during butt jointing. If your project has acceptance requirements, it is recommended to give priority to standard wall thickness products.
What are the commonly used wall thickness specifications?
The wall thickness grades we commonly produce include SCH10, SCH20, SCH40, SCH80, STD, XS, etc., covering most civil and industrial conventional pipeline working conditions. The specific grade to choose needs to be determined based on pipeline design pressure, medium, and diameter. You can send us the project standards or drawings, and we will assist in confirming the corresponding wall thickness.
Can it replace a tee of the same specification in an old pipeline network?
Standard wall thickness tees are produced according to general standards and have good interchangeability with conventional standard pipeline networks at home and abroad. Under the same specification, they can generally be directly replaced. However, old pipeline networks may have non-standard dimensions or special interfaces. Before replacement, it is recommended to confirm the diameter, wall thickness grade, and connection method of the original pipe fitting. You can contact us to provide the dimensions, and we will assist in checking.
How are the minimum order quantity and delivery time calculated?
For conventional small-diameter standard wall thickness stock items from DN15–DN100, the MOQ is as low as 10 pieces, and shipment can be made within 24 hours after order confirmation. For other diameters, customized specifications, and foreign trade bulk orders, please contact us to confirm the minimum order quantity and delivery time.
Which customization options are supported?
Wall thickness specifications can be customized according to standards such as GB, ASTM, DIN, JIS, etc. The diameter range covers DN15–DN1200, and it supports special reducing ratios, special branch angles, and flow-channel optimized structures. Material options include carbon steel, stainless steel, and alloy steel, and the connection type can be customized according to drawings. For foreign trade orders, English shipping marks, LOGO, and batch identification can be customized. Please contact us to confirm the specific solution.
