Duplex Steel Pipe Fittings for Structure Pipe-manufacture,factory,supplier from China

Duplex stainless steel tube has good welding performance, compared with ferritic stainless steel and austenitic stainless steel, it is not like the welding heat affected zone of ferritic stainless steel, because of the severe coarsing grain and the plastic toughness is greatly reduced, nor like austenitic stainless steel, is more sensitive to welding hot crack.Because of its special advantages, duplex stainless steel is widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, papermaking machinery and other industrial fields.

The elbow is a pipe fititng for bends in the pipeline . It represents the largest proportion, about 80% among all the pipe fittings used in the pipeline system. Usually, select different forming process for the elbows with different materials or wall thickness. At present,forming processes for seamless elbows commonly used by manufacturing plants are stamping,thrust,extrusion etc.. Classifications of Elbows:1 .Classified as materials: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, PVC, PPR etc..2.

Stainless steel pipe and fittings are supplied in the annealed condition to facilitate fabrication and ensure best corrosion resistance.

2507 Stainless Steel Pipe is a super duplex grade for which elements chromium, nickel and molybdenum are the primary alloyants.

introduction:Welded stainless steel pipe provides us a large diameter but low cost solution. Our welding process mainly is Plasma-Arc Welding(PAW), its biggest diameter could reach 3000mm. If other process is required, please state it in the requirement of stainless steel tubings.Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface.

According to the main chemical composition is divided into chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel; Can also be divided into acid resistant stainless steel and heat resistant stainless steel with performance characteristics; It is usually classified by metallographic structure.

Pipe flanges connect pipes, valves, pumps and other equipment in a piping system. Flanges are usually welded or screwed into the systems and then joined with bolts. The eight types of pipe flanges are available in round, square and rectangular shapes.Blind FlangesA blind, or blanking, flange is a round plate with no center hold (but with bolt holes) that closes the ends of piping systems.Lap Joint FlangesPiping fitted with lapped pipe or with lap joint stub ends often use lap joint flanges.

TP310s seamless/welded stainless steel pipe/tube for Instrumentation Stainless steel pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transmission pipelines as well as mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used to manufacture mechanical parts and engineering structures.

The grade of austenitic stainless steel is versatile and is widely used stainless steel. It is exhibiting high corrosion resistance for the wide range of highly corrosive environments. The type 304 and 304L stainless steel grade pipe is also exhibiting good machinability and is also having excellent weldability feature without or by adding the filler metals.Stainless Steel 304/304L Pipe & Tube is versatile stainless steel which is popularly used for making the tools or the parts that require excellent performance (formability and corrosion).

The Stainless Steel 904L Pipe & Tube is one great austenitic stainless steel alloy which is renowned for its amazing corrosion resistant properties. Moreover, it features some low carbon, and thus, it is the updated version of the same 904 range. It offers numerous benefits to the users; therefore, it is seen applied in various industries.

Super Duplex 2507 PipeSuper Duplex 2507 Pipe is a exquisite duplex cloth made steel pipe. The high-quality duplex is an alloy of chromium, molybdenum and nickel. The fabric has very excessive corrosion resistance houses and is resistant to pitting corrosion, crevice corrosion and uniform corrosion as well. The Alloy 2507 Seamless Pipes are produced via a technique referred to as the cold drawing. Cold drawn pipes are seamless or have clean surfaces. They are proper to be used in aesthetic searching and unique applications.

Stainless steel pipe are light weight and are widely used in the manufacture of mechanical parts and engineering structures.

This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded pipe (seam pipe) two categories.According to the different manufacturing process can be: hot rolling, extrusion, cold drawing and cold rolling these basic types, according to the shape of the section and can be divided into round pipe and special-shaped pipe, widely used is circular steel pipe, but there are some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal special-shaped stainless steel pipe.Shaped Stainless Steel Pipe1.Not easily rust, acid resistance an

Duplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel whose structure is a balance of ferritic and austenitic.

Stamping elbow is a kind of connecting pipe commonly used in pipeline installation.

Elongation :60 to 80%2. Tensile stiffness :100,000 to 180,000 psi3. Elastic modulus :29,000,000 psi4.

Butt welding ring loose flangeThe purpose of using butt welding ring loose flange is to save materials. The flange plate is made of low-grade material, and the pipe part is made of the same material as the pipe, so as to save material.Butt weld ring loose flange:1. Cost saving. When the pipe material is special and expensive, the cost of welding flanges of the same material is high.2. It is inconvenient for welding or processing or requires high strength. Such as plastic pipes, glass steel pipes and the like.3. Easy to construct.

s31803 Duplex stainless steel is a kind of  Medium alloy stainless steel,it's PREN value is 32-33, and its corrosion resistance is between AISI 316L and 6%Mo+N austenitic stainless steel.Duplex stainless steel has the characteristics of both austenitic stainless steel and ferritic stainless steel because it has austenite + ferrite dual-phase structure, and the content of the two phase structures is basically the same. The yield strength can reach 400Mpa ~ 550MPa, which is twice that of ordinary austenitic stainless steel.

Threaded flange refers to a flange that uses threads to connect to pipes. When designing, it can be handled as loose flange. The advantage is that there is no need for welding, and the additional moment to the cylinder or pipe when the flange is deformed is very small. The disadvantage is that the flange thickness is large and the cost is high.
