Schedule 40 Erw Steel Pipe, welding pipe with ordinary welding technology is not the same, the weld is made of the base material of the steel body melting, mechanical strength better than the general pipe. Smooth appearance, high precision, low cost welding seam height, favorable 3PE anti-corrosion coating. High-frequency welded steel pipe and...

ASTM A53 Erw Steel Pipe is hot-rolled coil through the molding machine, the use of high-frequency current skin effect and adjacent effects, so that the edge of the tube heating and melting, in the role of pressure extrusion welding to achieve production. Erw Steel Pipe  wall thickness classification table...

Seamless Stainless Steel Tubing Stainless steel tube is a hollow round steel tube, mainly used in petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial pipes and mechanical structural components. In addition, bending, torsional strength of the same, lighter, so it is widely used in the manufacture of...

Steel Pipes And Fittings  Low Carbon Steel Pipe According to the use of different sub-three supply: a, according to the chemical composition and mechanical properties of supply; b, according to the mechanical properties of supply; c, according to the hydraulic test supply. According to a, b class supply of steel pipe, such as for the use...

Class 1500 Lb Blind Flange, ANSI B16.5 Class marked with 6 pressure levels Respectively: Class 150; Class 300; Class 600; Class 900; Class 1500; Class 2500 High-quality products    Blind Flange sealing surface in the form of more types, FF, RF, MF, TG, RJ. It is the middle of the flange without...

From the production process to distinguish between casting flange and forging flange different, such as centrifugal flange is a kind of casting flange. Centrifugal flange is a precision casting method to produce the flange, the kind of casting more common sand casting organization is much thinner, improve the quality of many, less prone to...

Production process is divided into forging, casting, cutting, these three. Casting flange and forged flange Casting out of the flange, rough shape size, processing capacity is small, low cost, but there are casting defects (pores. Cracks. Inclusions); casting internal organization streamlined poor (if the cutting parts, streamlined) Forging...

Procurement of raw materials and re-inspection 3.1, all for the manufacture of forging flange raw materials procurement pipeline must be identified to the supplier. 3.2, after the purchase of raw materials must be re-inspection, qualified before put into production. Check the project is not less than the following: 3.2.1 Raw materials must have a...

Large flange production process features: large flange products are all welded products, no silk buckle. Large flange production process forging and rolling and splicing three. First cut into the appropriate sliver plate, the length of the sliver according to the specifications of large flanges. And then made with a roll ring made of a circle,...

Forging flange production process there are two Free forging the basic process: free forging, the shape of the forging is through some basic deformation process will gradually forging the blank. The basic processes of free forging are upsetting, drawing, punching, bending and cutting. The forging die is forged as a model forging and the...
