GB/T 31315 Q195 Cold Rolled Precision Welded Steel Tube For Mechanical Structures Product Overview GB/T 31315 Q195 cold rolled precision welded steel tube is a cold-sized mechanical tube designed for applications requiring tighter dimensional control, cleaner surfaces, and superior formability compared to ordinary ERW structural pipe. Governed by GB/T 31315-2014 standard, this product covers cold drawn or cold rolled precision welded steel tubes for machinery, vehicle,

Multi-Core Stainless Steel Seamless Tube For Shipbuilding Material A multi-core tube (also called a multi-line tube bundle) is a prefabricated assembly that integrates multiple seamless stainless steel tube “cores” inside one extruded plastic protective jacket . It is designed to route hydraulic, pneumatic, lubrication, and instrumentation lines through tight shipboard spaces with fewer clamps, joints, and installation steps. Specifications Construction: 2–12 stainless tube

ASTM A513 DOM Steel Tube ERW Cold Drawn Precision Steel Tube ASTM A513 DOM steel tube is a precision mechanical tubing product made by forming strip into ERW tube, welding, and then cold drawing over a mandrel to improve dimensional accuracy, surface consistency, concentricity, and mechanical performance. ASTM A513 covers ERW carbon and alloy steel mechanical tubing in round, square, rectangular, and special shapes, while Type 5 DOM tubing is widely selected where tighter OD

Bundy Tube – Double-Wall Copper-Plated Low-Carbon Steel Tube for Automotive Use Material Overview Bundy tube is a double-wall low-carbon steel tube manufactured by rolling a steel strip into a 720° overlap and copper-brazing the seam. This produces a concentric double-wall tube with a continuous brazed bond between the two walls. For automotive brake and fuel lines, this design offers: The mechanical strength and rigidity of steel The corrosion protection and brazeability of

SAE J527 Bundy Tube Double-Layer Copper-Plated Low-Carbon Steel Tube for Brake Line Material SAE J527 double-layer copper-plated low-carbon steel tube, commonly known as Bundy tube, is a precision-formed, copper-brazed steel tubing product used in brake, fuel, hydraulic, and refrigeration systems. SAE J527 covers brazed double-wall low-carbon steel tubing for applications that require reliable bending, flaring, beading, forming, and brazing, while ASTM A254 covers the closely

SAE J526 Welded Low-Carbon Steel Tubing (Coiled) for Brake & Hydraulic Lines Material SAE J526 tubing is an electric-resistance welded (ERW), single-wall low-carbon steel tube supplied in coils (or straight lengths) for automotive fluid conductor applications where controlled bending, flaring, beading, forming, and brazing are required.Important design note: SAE J526 material is not intended for single-flare applications due to a potential leak path associated with the

E355+N Carbon Steel Seamless Hollow Bars Cold Drawn Precision Tube for Mechanical Applications Material E355+N is a non-alloy carbon steel seamless precision tube grade, steel number 1.0580, commonly used in the EN precision-tube and mechanical-tube system. In practical sourcing, it is generally treated under EN 10305-1 for seamless cold drawn precision tubes and can also align with EN 10297-1 for seamless tubes used in mechanical and general engineering. The “+N” delivery

Galvanized Bundy Tube Hot-Dip Galvanized Precision Bundy Tube For Automobile Brake Material Galvanized Bundy tube is a double-wall, copper-brazed low-carbon precision steel tube designed for automotive fluid line service. In brake-line applications, the core value of this product is the combination of a compact double-wall structure, stable forming behavior, and protected outer surface for corrosion resistance. SAE J527 and ASTM A254 both describe this double-wall copper
