C70600 Pipe ASME SB 111 SB 466 C70600 Pipe | 90/10 Copper Nickel Seamless Tubes Tubing

We are well known Manufacturer, Supplier, and Exporter of Grade C70600-Copper-Nickel-Seamless-Tube. Copper Nickel C706 in bar, plate & sheet, tube, pipe, fittings, and flanges. Copper Nickel C706 is also known as Copper Nickel 90/10 because it is made up of 10% nickel or as ASTM B466 and ASME SB466. C706 is known for its moderate strength, weldability, and formability. The inclusion of controlled quantities of iron and manganese also give the 90/10 alloy an extraordinary resistance to general corrosion and stress cracking, These C70600-Copper-Nickel-Seamless-Tube are manufacturers using superior quality of raw material in accordance with national and international norms.

For purposes of identification, copper and copper alloys are divided into characteristic
groups, each group determined by its composition, and referenced by a system of
three-digit numbers originally designated by the Copper Development Association, or
CDA. Today, these designations have been expanded to five digits, following a prefix
letter ‘C’, and made a part of the Unified Numbering System for Metals and Alloys (UNS),
which is jointly managed by the American Society for Testing and Materials
(ASTM) and by the Society of Automotive Engineers (SAE).
100 Series (C10000) Coppers
This group comprises the pure coppers, those with a designated minimum copper content
of 99.3%, for high electrical conductivity.Also included within this group are the high
copper alloys, those withcopper contents of between 99.3% and 96%; which contain
additionalalloying elements such as beryllium, cadmium,chromium, cobalt, nickel, or
iron forgreater strength without drastically reducing the electrical conductivity.
200 Series (C20000) Brasses
These are the basic copper-zinc alloys which feature ease of manufacturing while still
maintaining fair electrical characteristics. These alloys are excellent for drawing and
forming while still providing good strength.
300 Series (C30000) Leaded Brasses
These are basically brass alloys that contain an addition of 1 to 3% lead to provide greater
ease of machining, blanking, shearing, sawing, and milling.
400 Series (C40000) Tin Brasses
These alloys contain 1 to 2% of tin as well as copper and zinc to provide greater
corrosion resistance while maintaining strength. These alloys find many uses in electrical
applications such as contact springs, fuse clips, terminals, and connectors.
500 Series (C50000) Phosphor Bronzes

Q. What the define of pipe fittings?
Pipe fitting is the occupation of installing or repairing piping or tubing systems that convey liquid, gas, and occasionally solid materials. This work involves selecting and preparing pipe or tubing, joining it together by various means, and the location and repair of leaks.
Pipe fitting work is done in many different trades: Plumbing, HVAC, manufacturing, fire prevention, and many others. Pipe fitters (sometimes called simply “fitters”) are represented in the USA by the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada.
Fitters work with a variety of pipe and tubing materials including several types of plastic, copper, steel, iron, aluminium, clay, and lead.

Q. What should I consider for buying pipe fittings?
A. Material, Size, Temperature and Pressure Ratings, Durability, Standards,surface coating etc.

Q. What are threaded fittings?
A. Thread fitting is the fitting with thread concetions,the regular screw standards are NPT and BSP.NPT is a U.S. standard for tapered threads used to join pipes and fitting and BSP is a family of standard screw thread types that has been adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread.

Q. The define of flange?
A. A flange is usually in the shape of a plate or ring which forms a rim at the end of a pipe when fastened to the pipe our factory can produce single forge base over 8000kg.

Q.Do you provide Material Test Reports (MTR’s) ?
Relevant documents according to inspection test plan will be provide along with goods.

Q.What is a standard used in pipe fittings?
A. Standards are certain authentication given in reference to manufacture and installation of the product . Some common standards are BSP, NPT, ANSI, ASME etc
