Straight seam elbow is a long - term customer order pipe fittings

Straight seam pipe bend performance good or bad in addition to the material and parts, manufacturing precision, heat treatment and so on, and the relationship between the assembly quality is also very important, so should according to the production and assembly method: according to customer's requirement on commonly used equipment to cut off the pipe length, also can manual cutting, the plane perpendicular to the center line of the pipe shall not be greater than the pipe diameter tolerance system and a half.Remove inner and outer burrs, metal shavings and dirt from tube ends.Remove anti-rust oil and dirt from the parts of pipe joints.Apply a small amount of lubricating oil to the thread and the contact parts of the blank clamp sleeve for the manufacture of straight seam elbow. Put the nut clamp sleeve on the pipe in order, and then insert the pipe into the bottom of the taper hole in the joint body and put the clamp sleeve straight.Tighten the nut while turning the pipe until it does not move. Tighten the nut again 1-1.25 turns.

The advantages of straight seam elbow are: in the installation process, the sealing performance can be done without leakage.Pressure resistance can not be damaged.Compensating performance The displacement performance of the pipe joint under nominal pressure should meet the standard requirements.Impact resistance: pipe joint under nominal pressure, continuous impact 7*10 times, no leakage, parts shall not be damaged.High temperature performance: under nominal pressure, the medium temperature is 90℃, the leakage is not allowed for 30 consecutive days, and the parts are not allowed to be damaged or residual deformation.The above briefly introduces the performance of straight seam elbow.

Straight seam elbow is divided into long radius elbow and short radius elbow, straight seam elbow material is divided into: carbon steel, alloy steel, stainless steel.The Angle of the straight seam elbow is divided into 45 degrees, 90 degrees 180 degrees and 60 degrees as required by the customer.Our company mainly according to the needs of customers to produce a variety of different types and materials and angles of different wall thickness of different straight seam elbow pipe fittings.All the purchase of our company's straight-seam elbow pipe fittings our company to provide a reasonable price to each customer, customer satisfaction, so that customers and our company has a long-term relationship of cooperation.

There are also many processing methods of carbon steel elbow fittings.Within the categories of machining, stamping, forging, rolling, rolling, bulging, stretching, bending and combined machining are used more frequently.Piping is a combination of machining and metal pressure machining.Forging: Use a forging machine to press the end of a pipe or part to reduce the outside diameter.Common forging machines include rotary, connecting rod and roller types.Stamping method: use a conical core in the carbon steel elbow to extend the tube end to the desired size and shape.Roller method: put the iron core into the carbon steel punch elbow, and use the roller to push the outer circumference of the round edge processing.
