Material: Carbon Steel Pipe Fittings, Stainless Steel Pipe Fittings, Alloy Steel Pipe Fittings

Product: Seamless Steel Pipe, Seamless Pipe Fittings, Flange

Type: Butt Weld Fittings and Socket Weld Fittings

Weld Neck Flange

Weld Neck Raised Face Flange is usually used with pipes which is suitable to apply high pressure, extreme temperatures, shear impact and vibratory stresses. Why Flange WN RF A182 Gr 304L 6″ 150lb is very common used for project?  Because the Weld Neck Type, 6 inch size and 150lb pressure

Butt Weld Fittings

Item 2,4 and 5 are butt weld seamless pipe fittings. They are 90 Deg Elbow and Equal Tee. For Butt Weld Elbow, it has LR and SR. LR means R=1.5D and SR means R=1D. Without mention, then we will take it as LR. When the R=3D, 5D, etc. There will be another name which is steel bend. For Butt Weld Tee, there are equal tee and reducing tee. The Pipe Elbow and Tee are play a important role in the direction of pipeline and usually used in high pressure compressed air, water, oil systems, steam, and natural gas.

Alloy Steel Socket Weld Fittings

A182 F22 Full Coupling SW is alloy steel socket weld coupling. To some extent,  A182 F22 CL3 is not normal as ASTM A105N Coupling and SS 316 Coupling in the industry.

Pipe coupling is a more effective alternative applicable to industries working at a lower speed. It is economical and have a high torque capacity, and are ideal to use with pumps.

Seamless Pipe and Fittings Package

The full couplings are packed with environmental poly bags. Then put them together with seamless pipe fittings and flanges in a free fumigation wooden case.

6” Stainless Steel 304L Seamless Pipes are packed in bundle.

What is MTC for Seamless Pipe Fittings

MTC is Mill Test Certificate that should be released to buyer after sent the goods. It contains all the specification. Including dimensions, sizes, weight, chemical composition, mechanical strength, state and used of delivery, standards, tensile test, etc. These information is to make sure the quality of ordered steel pipe and fittings, informs the buyer what situations suits engineering purposes.

This batch of goods has Inspection Certificate to BS EN10204-3.1.

What is BS EN10204-3.1

EN 10204 is European standard for the inspection documents for the steel products including steel line pipe, fittings, steel plate, valves, sucker rods etc. For certifying the results of the specific test is complied with client’s order.

It requires the manufacturer to show the actual test result for the steel pipe or seamless pipe fittings on sale. According the related standard sampling methods.

In this order, A403 WP304 90 Degree Elbow, Equal Tee and A182 F304L Flange were solution treatment and  A234 WPB Elbow and A182 F22 Full Coupling were normalization.

Stainless Steel Pipe Fittings Solution Treatment

Solution treatment refers to the heat treatment process in which the alloy is heated to a constant temperature in the high-temperature single-phase region, and the excess phase is fully dissolved into the solid solution and then rapidly cooled to obtain the over-saturated solid solution.

Carbon Steel Pipe Fittings Normalizing

Normalizing is a heat treatment for improving the toughness of steel.

Cooling process refines the crystallization grain of steel, which not only optimizes strength, but also improves toughness and cutting performance, reduces cracking tendency of components .
