The Cold Drawn Seamless Steel Tube from ZZ Group is a cold-drawn precision seamless steel pipe built for mechanical structure and hydraulic equipment, where fit and finish decide whether the part works first time. Repeated cold drawing passes on the blank deliver dimensional accuracy that hot rolled pipe cannot approach, along with a smooth, consistent surface. Outer diameter runs from ￠14mm to 159mm, wall thickness from ￠1mm to 30mm, and length from 1m to 12m, every one of them cut to your requirement, finished with standard sea-worthy packing.
On the specification side, ZZ Group offers the Seamless Steel Pipe in 10#, 20#, 45#, 16mn, 27simn, 20cr, 40cr, gcr15, 35crmo and 42crmo, with outer diameter ￠14-159mm, wall thickness ￠1-30mm and length 1-12m, each according to the customer's requirement, packed to a standard sea-worthy standard. The intended duties are mechanical structure and hydraulic equipment, where high dimensional accuracy and good surface finish keep machining simple and assemblies true. A high-precision cold-drawn pipe saves steel, improves machining efficiency and saves energy, savings that land on the cost sheet, not just on the print. Add strict tolerance ranges on inner and outer diameters, good smoothness, roundness and straightness of both surfaces, and uniform wall thickness, and you have a Metal Pipe that behaves the same from one length to the next.
Basic parameters of the cold drawn Steel Pipe:
● Material: 10#, 20#, 45#, 16mn, 27simn, 20cr, 40cr, gcr15, 35crmo, 42crmo
● Outer Diameter: ￠14-159mm, according to customers' requirement
● Wall Thickness: ￠1-30mm, according to customers' requirement
● Length: 1-12m, according to customers' requirement
● Packing: standard sea-worthy packing
The cold-rolled (drawn) family is broader than most buyers realize. At the heart of the family is the Seamless Steel Pipe, and each group around it exists because a different duty wants a different wall, bore or shape, with the drawing process giving them the accuracy the duty demands. Beyond ordinary steel pipes the group covers carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes and special-shaped steel pipes, and the list keeps going: low-medium pressure boiler steel pipes, high-pressure boiler steel pipes, stainless steel pipes, petroleum cracking pipes, machined pipes, thick-walled pipes, and small-diameter cold-drawn pipes with internal mold.
● Accuracy that hot rolling cannot match. Several cold drawing passes expand the blank's diameter step by step, and the result is precision and surface quality obviously superior to hot-rolled steel pipe.
● Tight tolerance range. Inner and outer diameters are held to strict dimensional accuracy, with good smoothness, roundness and straightness on both surfaces and uniform wall thickness.
● Steel saved, energy saved. A high-precision cold-drawn precision steel pipe saves steel, improves machining efficiency and saves energy along the way.
● Built for mechanical structure and hydraulic equipment. High dimensional accuracy and a good surface finish are exactly what these two duties ask for.
● Honest limits. Because of technological constraints, diameter and length are restricted to some extent, so planning around the available range is part of the deal.
● Made to order. Outer diameter ￠14-159mm, wall thickness ￠1-30mm and length 1-12m, all according to the customer's requirement, which is how the Cold Drawn Seamless Tube range is quoted.
● Sea-worthy by default. Standard sea-worthy packing is part of the spec, so the pipe arrives as it left.
● Tolerances you can build on. Multiple cold drawing passes tighten dimensions pass by pass, so accuracy and surface quality sit clearly above hot-rolled material.
● Machining cost that drops. High precision means less material to cut away, higher machining efficiency, and energy saved on every run.
● Specs that flex. Outer diameter ￠14-159mm, wall thickness ￠1-30mm and length 1-12m, all to the customer's requirement, not the other way round.
● Packing that survives the voyage. Standard sea-worthy packing comes with the order, so the Steel Pipe lands in the condition it was loaded.
● Direct supply, handled paperwork. Finished products are supplied directly and import customs clearance can be acted for, which keeps the buying side simple.
● Mechanical structure. Frame members and machine parts that need high dimensional accuracy without extra machining runs, a core use for this Cold Drawn Seamless Tube.
● Hydraulic equipment. Cylinder and line work where surface finish and roundness decide sealing and service life.
● Low-medium pressure boilers. Boiler duty within the low and medium pressure band.
● High-pressure boilers. The heavier end of boiler service, where wall and material are chosen to match.
● Petroleum cracking. Process piping for petroleum cracking duty.
● Machined parts. Feedstock that goes on to further machining, saving steps because this Metal Pipe already fits.
● Thick-walled and special-shaped pipes. Where a plain round section will not do, the shaped and thick-walled options cover it.
● Small-diameter cold-drawn pipes with internal mold. Precision small bores for applications that need an internal profile.
Q: What sizes can the cold drawn steel pipe be produced in?
A: Outer diameter ￠14-159mm, wall thickness ￠1-30mm and length 1-12m, all according to the customer's requirement.
Q: Which materials are available?
A: 10#, 20#, 45#, 16mn, 27simn, 20cr, 40cr, gcr15, 35crmo and 42crmo.
Q: How is cold drawn pipe different from hot rolled pipe?
A: A wool pipe blank or raw material pipe goes through several cold drawing passes to expand its diameter. Accuracy and surface quality are obviously superior to hot-rolled steel pipe, though diameter and length are limited to some extent by technological constraints.
Q: What is this Seamless Steel Pipe mainly used for?
A: Mechanical structure and hydraulic equipment, where high dimensional accuracy and good surface finish are essential. The cold-rolled family also covers boiler pipe, petroleum cracking pipe, machined pipe and more.
Q: Why does high precision matter in practice?
A: A high-precision cold-drawn precision steel pipe saves steel, improves machining efficiency and saves energy, and the strict tolerance range on inner and outer diameters keeps assemblies true. For a Metal Pipe on a machining line, that is the difference between a pass and a rework.
